Anyone gotten pet. ether like this?


I just bought a bottle of a barbeque charcoal lighter fluid that I know is pretty clean petroleum ether, funny thing though, there was a sort of stale urine smell to it that seeped even through my gas mask, I can pin it down prescisely, it was the exact same musty stale piss smell that you get in mouse cages, or the dwelling of other small rodents.

Has anyone ever found pet. ether with that sort of a smell to it? or any idea of whats causing it?

Does it go away if you extract the petroleum ether with Na2CO3 solution (for example)?

Where do you store your gas mask? ;) Maybe it's already been contaminated?
Do you notice the smell when not wearing it? I would suspect the quality of BBQ lighter solvent to be just above kerosene, minus some sulfur compounds. BTW some illegal drug precursors are reputed to smell like stale mouse piss. This is a classic description the cops use to describe a Meth lab. I always thought petroleum ether was like lighter fluid not like the higher boiling point BBQ lighter fluid and paint thinner. BTW I use paint thinner or Stoddard solvent ( automotive parts solvent) to light my BBQ fires. They all have a flash point of over 100F and I can't tell them apart. It won't be the first or the last time I've been mistaken about something :)

I am just using the BBQ fuel as a nonpolar solvent for an acid/base alkaloid extraction, it is doing the trick fine, but for some reason, stinks of stale piss, it just happens to be one of the very few clean OTC nonpolar solvents right about my locale, apart from toluene, which for some reason, costs almost £45 PER CAN:o

Vulture, at the moment, I don't actually have any Na2CO3, so I cannot try your suggestion, it isnt a chemical I often use, so I don't happen to have any to hand.

Mr.Wizard, I believe it is phenylacetic acid that reeks of cat piss, that is used in meth labs, and I store my mask in a cupboard with the rest of my chemicals and various bits and pieces of ammunition, I know it isn't the mask, I can smell stale rodent-cage all around the room the naptha evaps in, even without my mask on.

Got any baking soda? Boil a solution for a few hours. Then add some lye to claim the rest of the CO2 that didn't boil out.

Or not bother, depending on how suitable bicarb is alone... usually just makes extra gas.

That's probably because your local motor factor has sussed that petrol-heads use this to raise their fuel octane rating and has upped the price according to the demand.

Phenylacetic acid is the mousey smelling precursor....but I seriously doubt its that.;)

Oh and when dilute it (PAA) smells of guess what?.......

Honey of course!:D
