Mystery Oil in butane

Recommended Posts

A brother posted on facebook, that he found a mysterious residue in canned butane, so we decided to investigate. 

 

We fractionally distilled 21.3 liters of butane under vacuum and recovered .158 grams of mystery oil, or about 12 ppm. 

 

I then sent that sample off to a third party lab, with a mass spectrometer attached to their gas chromatograph, and picked up the results yesterday afternoon.

 

I 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 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 millionth, with a Permissible Exposure Limit of 2 ppm TWA for 8 hours.    That is only 56 times lower than PEL, so of more concern.

 

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.

Interesting data GW...

 

Might I question: Although you state the levels are not close to exposure limits per 1x, are any retained within tissue as a base that could build to toxic levels over time?

A very good question.  None that they have identified, but I am concerned about carcinogens and mutagens at really low levels, so I plan to take them out before using the butane.

I LOVE IT!   I always thought Butane was overall stupid idea, despite the "evidence" it is safe.    Glad to see someone using their knowledge to clean things up and get the bottom of this!   Great job Greywolf!  HIgh Five.

Here is the parts per billionth summary, as well as a summary of all the constitutes at both ppm and ppb levels, replete with CAS #'s.

 

We will continue the experiment by expanding to more brands and orienting the experiments toward total PPM as opposed to contents, continuing to use a third party lab. 

 

We've ordered a new clean 50# recovery tank for that purpose, and will resume after it arrives and I return from vacation.

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.

More to be revealed...................... .

 Ohhh this is like a good book, keeps getting more and more interesting!  Thanks for sharing this as you go Greywolf, I am fascinated in your scientific studies of this!

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.
