Update: If you use pentane to partition your cannabinoids to a non polar layer, you’re gonna have a BAD TIME
Update 2: Considering that EtOH has been acidified and enzymatically treated, it makes sense to neutralize the solution AFTER winterization, THEN recover the ethanol and THEN introduce hydrocarbon (heptane is the only hydrocarbon I will be using for LLE anymore).
If you do not do this, you’ll be fighting pH the whole time, because “pH change” of the hydrocarbon layer is going to be majorly reliant on agitation and will not be as completely neutralized as it would have been had pH steps been carried out in EtOH/water.
Update 2: Decided to skip degum, because this was a clean first pass 93% TAC.
Acid wash @ pH = 3 in Brine (Citric Acid)
Base wash @ pH = 8 in Brine (Sodium Bicarbonate)
Neutral Wash @ pH = 7 in Brine
T41 scrub @ 60C for 10 minutes, passed through a wetloaded column of MagSil and Silica.
I jumped from there to the roto without a neutralization wash and BAM purple…
I think I know why @Photon_noir suggests AGAINST pH washes unless absolutely necessary.
Anyways, reintroduce heptane, purple disappears completely, neutral wash with only distilled water and I lose 50% of initial yield to emulsions.
Recover heptane again, toss into a short path. Reflexed up to 205C at 250micron and it wouldn’t pull over—but in the BF it looked CLEAR—as soon as I reintroduced atmosphere, the walls of the flask turned purple again and streaks fell into the clear disty which looked red when poured into a jar.
Suggestions, pats on the backs and/or absolutely unfair ridicule accepted and appreciated.
I want to reiterate something I’ve said several times—a good chemical engineer does not a good chemist make. Know the difference and don’t assume you’re the best at both because you’re good at one of them.
Love,
Phil
P.S. Shoutout to all the homie that have been helping me out with this, I am absolutely relentless when it comes to reaching out to people and everyone in the community has responded graciously and with kindness.
Definitely noticed precipitated gums after an enzymatic degum. They’re in the crude regardless of cold extract, but they won’t destroy product quality in smaller quantities
