You can buy nearly anything submerged in ACN from Sigma Aldrich
Think Iām joking
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
Cough cough āVHS head cleanerā
And for those attending the GLG meetup after their lab work, the poppers may come in handy later too
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 Iāve never done any equipment designs that use pressure swing principles.
Iāll 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 isnāt anything especially tricky about the fundamentals of pressure swing systems other than the pressure requirement.
Obviously youāll want stainless instead of glass, unless youāve got access to a very meticulous, trustworthy, and slightly crazy glass artisan.
Doing a batch mode system seems easiest - itās possible that getting a proper two stage system working together might be difficult from an optimization perspective.
Even the most modern distillation systems Iām aware of are pretty inefficient from various perspectives, but pretty much all of them can be built with 1930ās 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. Iād happily put a fair bit of pressure into a triclamp system at ambient temperature. Iād think carefully about it if the temperatures and the pressures were going to be elevated.
