BHO Mystery Oil
Posted by Skunk Pharm Research,LLC.
A brother recently posted on Facebook he had injected around 6 cases of butane into a container and when he evaporated it off to see what was left, there was a heavier
residual oil that he described as smelling like a tire factory.
There are a number of possibilities offered on what it is, but no definitive analysis as yet, so we decided to run an experiment ourselves, with us in control of the variables such as cleanliness.
There are of course things that we know are in butane, such as
sulfur in the low ppm to ppb range, and longer chain oleaginous waxes, which is what all the XXXXXX refining is to remove, as they clog the small orifices of expensive butane lighters.
If you concentrate enough butane, you would expect to see a measurable amount of those left behind and they may explain the Mystery Oil.
As far as the smell, tires are mostly made of synthetic rubber formulated out of styrene and butadiene, so the butane present could explain a butyl rubber odor, if mixed with sulfur and longer chain alkane waxes.
All conjecture of course, so until we can get a clean sample into a lab for a HPLC/MS analysis, all speculation is conjecture.
I tried to conduct the experiment yesterday, but alas we only had one case of butane on hand and the
wholesale house was closed. One 12 can case turned out not to be enough, so I will repeat today.
I ran the one case of Lucienne through a brand new cold trap that I assembled out of new Mk III components, kindly loaned to us by Specialized Formulations, so that I had a pristine and uncontaminated unit for the tests. To remove any existing contamination beforehand, I first boiled in hot soapy water and wiped down with 190 proof ethanol. I did get some
light oil from this trial, but not enough to filter and send out for analysis.
I say filter, because the first thing that I saw was paint
chips from the outside of the can in the oil. What a tasty thought for those who can tap their butane and don’t subsequently clean the pot before running, or winterize or filter the oil.
While the sample was larger than the .05 grams needed for GC, it was small and full of paint chips, so I decided to rerun the experiment with more butane and add a coffee filter section to my test sled.
The oil didn’t smell like an old
tire factory, but like a light petroleum fraction (distillant), with a hint of butane odor, so the tire factory odor may come with a larger sample.
It readily dissolved in 190 proof ethanol.
Ethanol is a simple alkane alcohol, and simple alkane hydrocarbons do readily dissolve in it.
Just to make sure my memory was correct, I dumped some hexane in the beaker of mystery oil and ethanol, to verify that it did mix, because all alcohols don’t mix with simple alkanes like hexane. It did.
I also cut apart all of the cans and felt inside for lubricity. There was none.
I inspected all the welds for quality and the welds were all sound and unoxidized.
I also cut apart the valve to better understand why lubricant would be required. It is is a simply made plug valve and needs no lubricant.
PS: Don’t cry ya’ll! The spill in the picture of alcohol is actually water from taking the cold trap out of the hot pot, not $37/1.75L 190 proof.
Today I will pick up a long case of Lucienne and try again.

Well, 72 cans were enough to get a good sample and I will drop it off at a HPLC/MS lab today. I added a filter section this time, so the sample was paint chip free and appears to be a light petroleum fraction, with a light petroleum odor. There was no tire factory odor, nor the smell of sulfur at this concentration level and I will refrain from conjecture until I see the analysis.

OK, I picked up the test results and am still going through it a line at a time, pulling up the MSDS sheets, starting with the items of concern.
The first thing to keep in perspective, is that the total oil was 12 ppm from 21.3 liters, so the PPM in the study should be divided by 1,000,000 and multiplied by .000,012, to get the concentration.
That concentration number X 1,000,000 will give you parts per millionth.
In summary, there were simple Alkanes present as long as C-16, which are not of health concern at the levels present.
In addition there are aromatic Alkenes present, that are of serious concern, but not at levels remotely close to exposure limits.
The concern with those Alkenes is really not reaching toxic limits, but the fact that some are known carcinogens, mutagens, teratogens, etc.
IE: Cyclohexane, isocyanato, which most likely came from the gaskets and seals used in the cans and process, because it isn’t found naturally in butane.
Nasty bad shit, with an no exposure limits established and an intravenous LD-50 mouse of 13 ppm and present at the level of .000000001728 concentration, or .001728 parts per millionth. That is about 7500 times lower than the LD-50.
Another bad nasty present was Benzenamine, 3,5, at the levels of .035778 parts per billionth, with a Permissible Exposure Limit of 2 ppm TWA for 8 hours. That is 56000 times lower than Permissible Exposure Limits.
Benzene 1,1 showed up at a concentration of .000000003678, or .000003678 PPM, with a Permissible Exposure Limit of 110 ppm TWA 8 hours.
I could go on, but it will take me awhile to pull MSDS sheets for the whole list, so I’ve attached the raw data. Sorry the quality isn’t better, but the original is barely readable and this was copied at 1200 bit resolution
Even if nothing is present at levels of serious health concern, I would prefer to not have any of that stuff in there, so in addition to fractional distillation using vacuum, we will be experimenting with Bentonite filters.
Here is the parts per billionth summary: You will note that there are redacted lines of scary stuff. Those were redacted by the lab itself, as it is their carrier solvents used for the tests and were not present in the original sample.

I’m not clever enough to outsmart this edit program, and it continues to thwart my adding anything at the end, so here it is in the middle, and I’ll let Joe sort it out later.
This experiment was designed to determine the contents of the mystery oil to the ninth decimal place, and I believe has accurately done so.
It was not designed to accurately determine the weight to the ninth decimal place, so that will be the next round of experiments. For that purpose, I’ve ordered a fresh 50# refrigerant tank, as all of ours have had both n-Butane and lighter butane in them, so can’t be relied upon to be un-comtaminated themselves.
I’ve decided to rely on a third party lab to determine exact weights, after which we will have our in house chemistry brain trust The lab technician that I work with, is on vacation and I’m fixing to be, so it may take a couple weeks to come up with a formal plan.
My intent is to determine actual total ppm as compared to advertized ppm, and infer that the components are the same as the first detailed sample.
Readers have commented on having found more oil in other brands, and even in the same Lucienne brand that I tested, at levels that are triple the 50ppm limits they are certified to contain. If that is the case, I plan to make that information public and a third party documentation will be cleaner and come in handy in case of lawsuits.
It would be prohibitively expensive to test all butane sources, but we will test the half a dozen or so primary ones used for extraction, including Airgas, Praxair, and Matheson.
I’ve also picked up a couple of cases of specialty butane typically used for cooking, at the suggestion of Skyhighler, and will be fractionally distilling them, to see what the relative oil content is and if mercaptans are detectable.
A point that I hope ya’ll keep in perspective, and that is that even at the higher ppm that others are discovering the oil, the ppm of the evil spirits in the finished product, would still be under limits set by NIOSH.
Having said that, as I would personally rather not have them there at all, we will hence forth vacuum distill all butane, regardless of source, before using it in our extraction process.

It is taking awhile to sort through to these items, so for those of you who wanted the complete names and a more legible copy, here are the legible names and CAS#’s at the bottom of the page:

OK, I dropped off a new sample of Lucienne in the can at Specialty Analytical, as well as two cans each of Skyhighler’s Iwatani and Gasone brands for ppm testing. I expect the results by Friday, which will be third party and should cut through any concerns about my accuracy.
Cost per run was $75/ea, so I limited it to these three brands, with double tests on the Lucienne. We will test other brands of interest at a later date, after we see what we get with these tests.
I discharged a can of Gasone and Iwatani into a bain marie for a sniff test, and they both definitely have mercaptans added, so even if they are ultra low residual, our sensory threshold for ethyl mercaptan is 2.8 parts per
billionth., and the final oil would taste and smell of it.
Damn nice flame though! I also ordered a Iwatani creme brulee torch head on sale, and it works better than my propane plumbers torch.
Hee, hee, hee thanks Skyhighler for setting me up with a slick new dabbing torch and more than a years supply of butane for it!
Although I wasn’t able to get the same lot of Lucienne that I tested before, because I picked up the last 6 pack at the distributor, I was able to get two different lots of Lucienne from a store shelf, so we can test for control. If they are all significantly different, it will support an out of control process theory.
I also talked to Marty about how we could further refine the tests on the items of interest, specifically just the compounds that that are considered evil spirits, despite their low levels. He is reviewing the list and costs for individual standards and we will discuss further later this week.
Still nothing on the list remotely close to established permissible exposure levels, so far thousands or millions of times below if calculated for the residuals in the extracted oil itself, but still looking and listening for input.
More to be revealed…………………..
9-23-2013
As ya’ll may have noticed, there is considerable controversy on this project, so I would like to put the conflict in perspective, as I see it.
We analyzed a sample of the residual oil from butane fractional distillation to the Parts Per Billion level and have a GC/MS printout. That means that in addition to retention time in the GC column, we have the component peaks from the mass spectrometer.
The argument has been made that isn’t accurate enough, even though the residuals of the evil spirits in the extracted oil, would be thousands to millions of times below published permissible exposure levels.
It is absolutely true that we can buy individual standards and refine our breakdown of the peaks of aromatics, where there are minute differences in the molecule, but surprises on the order of 1000, or 1,000, 000 are highly unlikely.
We are more likely to find that although some of the benzene peaks on the parts per million list, do break down into other benzene compounds, not all benzene compounds are listed as a carcinogen, so the levels in the oil may actually be reduced further.
We are continuing to work with Specialty Analysis to identify compounds worthy of refined examination, and they’ve expressed special interest in this project, as well as willingness to purchase the individual standards for evil spirits in sufficient quantity to bear closer examination.
The project is advancing in an orderly manner, without MO Jack’s participation, and the results will be all third party from a certified forensic lab, so I will be just another spectator and hopefully above reproach this time.
I disconnected communications with MO Jack, because the hoopla was greater than the project itself, and he was becoming confrontational. He seemed fine with questioning my empirical results, but not with me questioning him.
Some of his statements were also directly refuted by the individuals whom he quotes, leaving me to choose between their statements and his.
I also found bits and pieces of my statements on other forums, without the rest of my qualifying statement, which I consider to be stacking the deck and misleading.
If you read the comments column, you will also find that he has a SCFE CO2 system on order from Eden Labs, and will be in direct competition with BHO extraction, so I have other reasons to be concerned about his impartiality.
Regardless whether those issues are my error or not, there is no question that we can resolve what is in the butane without spending an even greater amount of time nit picking details at the parts per trillion levels and bickering amongst ourselves.
Best wishes to MO Jack with his own experiments, wherever they may lead him.

Still awaiting lab results for the last three, but did get the results for two different lots of Lucienne, as well as Gasone and Iwatani.
The nice lady in the office and I miss-communicated earlier in the week, and I incorrectly reported the last Iwatani results as Lucienne. Even the ppm is incorrect, as the Iwatana cans are 394 ml instead of 300 ml.
That aside, and cutting to the chase, here are the correct Parts Per Millionth residual contamination, after evaporating away the butane, as reported by a certified third party analytical lab, for the first three brands.
The, balance of the information on other brands to follow, ostensibly Monday:
On the subject of refining our search, Marty ordered the standards required to further investigate the aromatics detected in the ppm range, as well as the cyanide compound in the ppb range. More on that after the standards arrive and more experiments are conducted.

The moment some of ya’ll have been waiting for has arrived, with the actual ppm residual contaminants in butane, by some of the common brands, as well as a couple not commonly used for butane extraction for comparison.
No hoopla or fanfaronade, just the actual ppm residuals by brand, as measured by a certified third party analytical lab.
Note that the ppm in the Gasone and Iwatani include Thiol mercaptans for leak detection. Thiols are alcohol analogs, where the oxygen atom is replaced by a sulfur atom and adds a garlic odor.
Note that the highest ppm found in any brand was 7% of their certified maximum of 50 ppm.
Also note that except for Lucienne, these were single can grab samples, and Lucienne is only two different lots, so the differences between brands, especially by the same refiner, may even out. IE: Lucienne and Newport.
They may not too, as the same refiner doesn’t necessarily mean the same refinery, which could also account for the differences.

So now that we have two bits of empirical scientific data, derived by a certified third party lab, instead of the anecdotal information on Facebook and the web that we started with, lets do the math to put this in perspective.
The previous part per billionth analysis showed 1,4 Dichlorobenzene at a combined total level of 55 parts per billionth, or .000,000,055. We all agree that we want no part of 1,4 Dichlorozenzene, because it has been declared a carcinogen, and given a low TWA CEIL of 110ppm by NIOSH.
http://www.sciencelab.com/msds.php?msdsId=9923722
55 parts per billionth in the concentrated residual itself, is 2000 times smaller than 110 parts per millionth TWA Ceiling imposed by NIOSH.
It will in addition be further diluted in an extract, considering that at the worse case total residual contaminant found was 3.5 ppm, besides being dilute in the extracted oil itself. Lets look at that math.
.000,000, 055 X .000, 0035 = .000,000,000,000,192 or 200 parts per quadrillion in the butane used for extraction.
Assuming a 40 gram trim extraction, using 300 ml of butane, and yielding only 10%, 300 ml butane would deposit .000,000,000,058 ml of 1,4 Dichlorbenzene in 4 grams of concentrate.
.000, 000, 000, 058 ml X 1.2475 gms per ml = .000,000,000,072 grams of 1,4 Dichlorobenzene in 4 grams of concentrate.
.000,000.000,072 grams divided by 4 grams =.000,000,000,018 or 18 parts per trillion.
110 ppm TWA Ceiling (.000, 110) divided by residual 1,4 Dichlorobenzene level of 18 parts per trillion (.000,000,000,018) = 6,111,111 or about one six millionth (1/6,000,000th) of maximum allowable exposure level.
4 grams of oil will produce about 20 200 mg hits, so each hit would be about 1/20th of 1/6,000, 000, so exposure per hit would be about 1/1,200,000,000 of the 110 ppm maximum.
Soooo, now that we have put things in perspective, where do we go from here?
We are planning some more testing of different brands and sources and further refined testing of all the evil spirits, but we have come far enough to know that while we would prefer to not have the unwanted contaminants in our butane, its presence is thousands, or even billions of times below published levels of concerns by health professionals.
We’ve also learned that it is easy to remove, using a cold trap and a refrigerant recovery pump, so those of you with the required equipment can take it out, making the point moot.
That is what we now do, because we can, but continue to use the oil we produced before we started fractionally distilling the butane.

The Colibri and Ronson sample results arrived and are as per the following chart:
Given the price and hoopla, I expected the Colibri to be lower. I wonder if it is the same product, after the company was bought out?
To consider, is that except for 2 sample lots of Luciene, all of these are single grab samples, so we don’t know what the median, mode, mean or standard deviation is.
More later, after we test Airgas, Matheson, and Praxair.
The lab asked for more time on the detailed component analysis, as well as the followup experiments for MO, to attempt to reconcile the differences between his PPM rates and theirs. More as that develops.
The good news, is that they’ve agreed to start running cannabis samples, and have more toys than any of the local cannabis labs, such as GC, MS, HPLC, etc.
