Evaporating naphtha
#16388251 - 06/15/12 11:55 PM (11 years, 8 months ago) |

I pulled my pan out of the freezer and poured off the excess naphtha so I could let the x-tals dry. After 7 hours of letting the x-tals sit, there was still some naphtha in the pan! I thought this stuff was suppose to evaporate in a few hours. Do I need to pour off the excess naphtha then fan dry the x-tals?

Maybe flip the dish or point a fan on them, avoid doing this indoors where you can blow shit up but ya sometimes you gotta push the naptha to leave unless you might have got some of the lye solution in the final product =\ Try heptane next time it treats me so much better

lye in the final product? sounds shitty.. but a man once said; skip the freezer and use fanz you can refine the final product once evap is done

I didnt use lye, i did an A/B tek. But with heptane, do you use it the same as naphtha and does it evaporate easier? And where do you buy it?

The liquid in the pan is WATER. Evaporation is a cooling process. Water from the atmosphere condensed onto the surface of the thin layer of cool naphtha left behind in the pan. This is an unavoidable but tiny source of water and a common cause and complaint of wet and/or disappearing crystals, as I've repeatedly advised.
The vast majority of the water in your pan was the result of setting out the freezer-cold pan. Think glass of iced tea in summer time. Next time try draining your crystal containing vessel back into the jar until it is nearly room temperature. Once the container is WARM, condensation stops. THEN and only THEN can you lay the pan flat and not have this problem crop up. Use a small fan. It will solve your problem.

Naph is not easy to evap Could use a double boiler set up to warm it and add some extra ventilation
Don't get it to warm... Why I suggest the double boiler set up

i'd disagree  i still think freeze-evap is unnecessary, altogether.

I disagree... Freezer evap works just fine, the only problem being the water in the pan

I don't do any "straight evaporation" presay.
I just precip, then dump through a filter and just fan dry it in the filter and it comes out fantastic =]
