How to extract and refine salvinorin using just acetone and 99% isopropyl with a minimum amount of verbage and no photos. This method does not use naphtha and goes strait to the use of isopropyl. Add Comment (3 total) "Isn't Salvinorin considerably less soluble in naptha than in isopropyl AND the lipids are more soluble in naptha than in isopropyl? As such, I'd have thought you'd get a more efficient wash of a crystal extract using naptha? 25% loss sounds like rather a lot!" --Ian, 01/08/07 "The microscopic leaf particles are easily removed by mechanical filtration through a fine poured filter paper. Toilet paper even!" --Ian, 01/08/07 "The first comment above is not clear - naptha is a broad label for a mid-stage crude oil extract; some lipids (another broad label) are plenty soluble enough in naptha and petroleum spirits. It is possible to speed up naptha washes by getting the temperature right." --Ian, 01/08/07
