Just bought a Kontes distillation apparatus for fractional distillation. I want to distill under vacuum, but can't figure out how to calculate temp difference that the vacuum pressure will change. Like 157* C to boil off THC, but under pressure using ethanol, changes the temp to....? Anyone?

HolySeed Reviewed by HolySeed on . Vacuum and fractional distillation I just love it when a plan comes together! Here is my new rig for vacuum and fractional distillation undergoing shakedown boiling water this morning. I followed by removing the hexane from an hops oil extraction and then washing it in ethanol and vacuum distilling that off to leave an absolute. I also picked up an Alhin condensor and a soxhlet, for refluxing, isomerizing, and soxhlet extractions from hash. Tomorrow I will try it on a cannabis oil run. Hee, hee, hee, snicker, Rating: 5
