Alas Mercaptan, recently I got sprayed with liquid propane one evening when
the filling person overfilled my 7 gallon propane tank and I was next to
it, my clothes smelled like propane all evening, actually ethyl mercaptan,
neat propane, is odorless.
The book 'Ignition' talks about burning mercaptans as test fuels. It says
flies were attracted to the test facility during the program.

A bit off topic except for the thio part.

Right you are on the smells. I've occasionally crossed paths with some
I used to consult at a chem plant that made mercaptans. My clothes would
reek at the end of the day; I always felt bad for my seatmates on that
Amarillo to Albuquerque flight. My wife made me strip off my clothes in the
garage.
During my jr year at Northwestern I did a year independent study project
with an org chem prof. James Marshall, has over 220 pubs in the J. of Org
Chem. At one point I did a reaction with some mercaptan. When finished, as
was SOP for the 70's) I poured the residue down the drain. A while later a
couple of chem lab TA's show up and wonder if we have any idea what that
horrible smell might be. My labmate, a 1st yr grad student who was my
supervisor and I denied any knowledge of it. Ah, the good old days.
Sorry off topic...Brian
