So, if one is working in a second floor apartment, I assume attempting to evap. naphtha indoors is a terrible idea. It even seems like it wouldn't be advisable to evap partially until super-saturated then freeze precip either, as fumes would still be heavy. So my question is, how would one go about doing this with naphtha in a closed environmen? A window could be opened, especially at night time, I guess, but I'm not sure how much that would help. Is it possible to just freeze precipitate out of the full amount of naphtha used for the pull?

Perhaps there is a different, more friendly solvent that should be used to pull?

Also, when working with naphtha at all, would you guys recommend using a respirator?

Thanks in advance...

If you are worried about naphtha stinking out your apartment, then just freeze precipitate rather than evaporating the solvent. I have never had any problems with naphtha smelling out my home after freeze precip.

I hope that helps some.

The trick is to use the minimum amount of naphtha possible for each pull. If extracting 100g of bark I use 50ml per pull and as the alkaloid content of the aqueous phase becomes less and less, reduce the amount of naphtha. Make sure the vessel is thoroughly agitated several times over the course of 2-3 hours for every pull and there will be no need to do a partial evap before each freeze precipitation.

That's right. Many small pulls are always more efficient than fewer big ones.



Swim uses even less - around 20 ml per pull. A sep funnel helps her to work with very small amounts of naphta.



A more radical solution would be to assemble a simple distillation setup. It's an easy and fun weekend project. While reducing your pulls you will be recovering most of your solvent and cleaning it at the same time. Just make sure there is no open flame anywhere close to your setup.

How would you go about doing that?

I wouldn't trust something I made up myself to to distill solvents. But I love the idea. I'd save a hell of a lot of cash for starters.

SWIM needs to redistill about 600 mL xylene in his apt.
he will do a vac distillation to speed up the process, and pack an inline vac filter with AC to help eliminate the smell.

lol

d-Limonene

and it pulls soooooo much more than naphtha!

Do you just replace the naphtha with d-limonene in a STB tek? Or is there something else that needs to be done to make d-limonene effective?

With d-limo you will have to salt out the DMT and then freebase it again. Two different ways of doing this: FASA method and BLAB Jazz. There are more, but those came to mind most quickly.

this is about 250 mL of it distilling. no smell of it whatsoever
