Anyone have any methods of evaporating it indoors that are safe? I live in a small room with poor ventilation and am trying to be creative. Any chemicals that will absorb the solvent vapors?

Not really. Evaporating without ventilation is very dangerous! Try using a fan maybe?

Wouldn't that just blow the fumes around the room? So there are no chemicals that can absorb solvents?

With the window open it will blow fumes outside. Is there no window?

But about the chemical to absorb organic solvents in short there is no simple way to do it thats practical for most people. Ah yes I forgot to add distilling would work. But again most people don't have that kind of stuff set up.

Carbon filters absorb lots of solvent fumes. Get an air purifier that has a carbon filter in it. It will help, but not completely.

I recommend putting your solvent in a container that is air tight that has two vinyl tubes connected to it. One tube goes out the window; the other tube is connected to an air pump. The pump pushes air really fast through the container and out the window. The fast air movement will quickly evaporate the solvent. This is how SWIM did it before he had a still. Now he distills the solvent instead.

I think I will try the carbon filter. Might try to distill though. What temp does the solvent come over at and what solvent do you use? Also, do those temperatures damage the goods at all?

Depends on the solvent. Usually on the bottle it sais their boiling point. Also depends on whether or not you distill under vacuum. As low pressure means lower boiling point.

SWIM only evaporates acetone, which he can keep on top of a cabinet without even a hint of odor. SWIM used to evaporate naphtha on top of a crock-pot next to a bathroom window with the bathroom's fan running and the door closed, and he never smelled it anywhere else in the house. SWIM would never dream of evaping xylene or toulene, however.

Yeah evaporating xylene or toulene without proper equipment will make your whole house smell like a gas station! YUCK!

How do you do an acetone extraction? I thought the salts weren't soluble in acetone?

The FASA Method

Basically, if one uses standard STB or A/B with toulene or xylene, one could precipitate the salt form right out of the NPS using fumaric acid and acetone, which would then only require drying of the salts, which could be done in an oven. One could then use washing soda or lime to basify and pull with acetone. This is the only point at which evaporation is necessary. Acetone dries very fast and its odor, though quite powerful, does not travel far at all.

if you need to evaporate for some reason.. NEVER DO IT INDOORS! get yourself a hotplate (like the ones to keep food warm on) and a long extension cord and do it on your balcony. if the extension cord is thin enough you can even close the door so no fumes will get in. a friend of mine does it that way. works like a charm. you should watch out for rain and kamikaze insects tho. kamikaze insects usually commit suicide by jumping into the pool of solvent

and then they will take their last crap in your spice. insect crap is an impurity which is hard to remove.

but I also cannot stress enough to go the FASA way!
