Can somebody take the trouble to provide any links to forum posts or anything else describing the process of defatting ? Thanks.

Gotta say, I don't really get that. Why choose between de-fatting and re-crystallizing? Why not do both? Defatting is the easiest way to rid yourself of (or minimize, anyway) these fats and oils, and it couldn't be any easier to do. Just three 200ml xylene pulls eliminate a coinsiderable amount of gunk, and you lose nothing from the yield. So where's the downside?
5-6 times of 200ml will do for defat. May have to do more if after the 6th time the solvent still cokes yellowish.omega-scar said:How much solvent should I use for 3600 ml of acidic liquid ? I understand the defat must be repeated until in comes clear, but what quantity is a good quantity to begin with ?
