I still don't get why bother with the freeze precipitation?
I mean, the naptha is completely evaporated within 30 mins, and then you scrape up the product. How is this different to freezing, pouring off excess naptha and letting the rest evaporate, in terms of what your left over with. Freezing takes at least 12hrs
