So yeah as the title says, whilst extracting ,I had used up my last 50mls of escort camp fuel that I've had for several years. I figured that I would buy some fresh naphtha for final freeze precip and was having a seriously hard time finding a good naphtha (canada) so I settled for a lighter fluid called emzone lighter fluid....Well anyway the evap test seemed to come out clean although very very slow so I went ahead and did a freeze precip in a shot glass.

Now it has been several days and my product still smells like fuel which is a red flag...So I did another evap test using about 20ml in a shot glass and yeah it left some oily residue.

Is there anything that I can do to save my 350mgs? I would think that if I could find heptane or even better naphtha then do a few re-X and It would probably be salvageable.

Mini A/B - pull into vinegar, evap, base with sodium carbonate or lime, pull with acetone or an alcohol, evap for goo.

sure sounds like a good idea to me! Yeah thanks a lot for the tip downwardsfromzero
