Winterizing in isopropyl alcohol

[coppertop]

Any reduction in yields after the first extraction using the reclaimed solvent? I’m wondering how much water is retained with isopropyl by itself forming an azeotrope at 91%.

Just kidding. Found that info here.

Iso vs ethonal

@EndlessOps The ethanol:water azeotrope is an almost perfect solvent for cannabis resin, especially at low temperatures. It has the unique ability to pull only cannabinoids and other components of the resin without pulling epicuticular wax and vegetable oil. Isopropyl alcohol has a higher affinity for wax and some oils than ethanol does. It also has a higher boiling point and sticks around more readily than ethanol. Using an azeotrope, however, of 87% IPA to water may make it behave a littl…
