Wal fornicate!!! The sample size was too small, so I get to do it over again today.........
On the other hand, I did learn a few thangs I can share.
I ran the only case of Lucienne we had on hand through a brand new cold trap that I assembled out of new Mk III components, which I first boiled in hot soapy water and wiped down with 190 proof ethanol. I did get some light oil, 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), 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.
