Introducing Refine Cannabis Extract - RxCE

You can buy nearly anything submerged in ACN from Sigma Aldrich :eyes:

Think Iā€™m joking :stuck_out_tongue_closed_eyes:

This is indeed the main reason I keep quiet of its powers to who ever works with ACN have poppers close at hand
If deu to labor you have been around it a lot in a short time frame take a Whiff from a popper every once in a while

Your first popper experience should be
Seated since it s a muscle relaxer and your legs can get wobbly

And for those attending the GLG meetup after their lab work, the poppers may come in handy later too :melting_face:

Althou membranes will probably outperform distillation to purge your Acetonnitril I am seriously looking at setting up a pressure swing distillation rig Ro kill the azeotrope
Acetonenitril pulls water from biomass and the surroundings so the water content picks up fast and the azeotrope is gnarly with a very high content of water
Calcium hydrate has thus far been my solution but the kg s needed are becoming an isseu as is the drying of the calciumhydrite after use so a solution needs to be figured out
Pressure swing distillation seems a solution and althoug the concept seems easy made from triclamp parts is a thingy
If anyone has made a unit or has better diagrams than the usual from papers I would be very interested

Pressure swing distillation is something I looked into a while ago but never had a reason to explore it beyond reading some papers on it, and Iā€™ve never done any equipment designs that use pressure swing principles.

Iā€™ll take a poke around the topic and see if anything jumps out at me.

After a quick review of common designs it looks to me that there isnā€™t anything especially tricky about the fundamentals of pressure swing systems other than the pressure requirement.

Obviously youā€™ll want stainless instead of glass, unless youā€™ve got access to a very meticulous, trustworthy, and slightly crazy glass artisan.

Doing a batch mode system seems easiest - itā€™s possible that getting a proper two stage system working together might be difficult from an optimization perspective.

Even the most modern distillation systems Iā€™m aware of are pretty inefficient from various perspectives, but pretty much all of them can be built with 1930ā€™s technology, and anything that can handle the pressure should get the job done for you.

Do keep in mind that the pressure ratings of things tends to go down with heat. Iā€™d happily put a fair bit of pressure into a triclamp system at ambient temperature. Iā€™d think carefully about it if the temperatures and the pressures were going to be elevated.
