water+lye contamination in the naphtha after extraction? normally it's easy to spot because the mimosa is so dark, but well, who knows. Did you perform a sodium carbonate wash?

Your condition sounds pretty bad. I would definitely give my lungs an extended recovery time. I know a person who fucked their lungs over from a chemistry experiment gone wrong (in the university) and this person will never be able to work in a lab again, let alone inhale cleaning agents or any other solvents that we take for granted. So take care you don't make the situation worse and do permanent damage. It's not fun.

I find it hard to believe that your naphtha is clean if stuff freezes out straight out of the jar. Are you using a closed jar so that no moisture can get in? it's never happened to me or anyone I know of. Plus what you describe doesn't sound like the effects I would imagine one would get from inhaling fuel or fuel residue.

The question is - can this be reproduced by an independent party? Someone else using the same solvent ever have these problems or can test a clean batch in the freezer? I know for certain my naphtha doesn't do what you described. I'd be interested to know what really happened. it just doesn't seem like it could be -> it leaves nothing when evapped but when frozen something falls out? which then turns to liquid and evaps but leaves a residue? sounds like something got into the naphtha during its stay in the freezer or somewhere inbetween.

anyway, I might be wrong. Do take care, and I hope your lungs heal well.

much love
