On reusing non polar solvents

[indydude19]

i recently reused naptha in a AB ACRB extraction for the second time, certainly a good amount of plant fat suspended in the Naptha, but it produced a nice yield of white fluffy DMT

Did you freeze precip? What vessel did you use?

Good to hear, regardless.

Yea both times, but the second time i used it i reduced by about 1/5 before freeze precipitating. I used a real wide glass jar, about 8 in. diameter. I also reused it again and got a good amount of slightly yellow crystals that im going to re-x.

Bump.

It should be mentioned here that using reused solvents is not about pulling backsalted liquids, it would defeat the purpose of backsalting.

That is why in Earthwalkers's
Simple clean-up for NPS pulled from ACRB ( mini AB )
the backsalted liquid is pulled with fresh NP, not reused NP.

Step 5
Now you can pull just like with the extraction mixing and let seperate x 4 now pull with fresh hot naphtha I usually mix ( approx 50ml - 70ml ) for the first 2 pulls ...

I'd like to add that I have some naphta that I have used quite a bit over the years, but I am going to dispose of (in a proper manner).
It seems to exist in a permanent state of emulsion, it doesn't clear up even with vinegar and base washes. It is still usable for extractions, but it is frustrating to have to deal with emulsions every time I salt out the DMT with vinegar.

Newer naphta doesn't have this problem when used in the same extraction.

The naphta I have is slightly heavier one (sold as Terpentine in the Netherlands), with a small percentage of aromatics; hence the saltings.

Here is a way that works for me to reuse ethyl acetate. It can dissolve acids and absorbs some water, so there are a couple extra steps.

Wash used ethyl acetate with sodium carbonate saturated water shaking vigorously. Acid removal can be optionally checked with a strip of pH paper. Separate water layer. Put solution in freezer overnight and filter out ice crystals.
