> But on fridge come back little later and it was one big white not freezing crystls but powdery crystals
when they separated into two layers, where did the powdery crystals go, up or down? if they went up, you are in the money dude, if they went down, so sorry.
couple pointers on that test, it needs be a saturated bisulfite solution, ei keep adding bisulfite to h2o until no more will dissolve and it starts to settle out on bottom of test tube. I often don't even remove the excess, as when the ketone reacts, the excess will go into solution and maintain saturation. If there are alot of contaminates in your 'ketone' you will require a small amount of alcohol in your mix, otherwise the contaminates will inhibit crystal formation. say 5mls EtOH for a 20ml saturated solution, MeOH works also. Prerefrigerate you saturated solution, and it needs shaking like hell, often sveral times, a little ketone reacting each time.
As far as directions go, try to follow in LabTops footsteps, he didn't delete half his posts on board like KRZ did, which may indicate a clearer conscience. If you notice that O2 is the shit thread, everyone who FAILED was following a recipe posted by KRZ (only falsly validated by Frost), but you wouldn't know that unless you were around before he deleted it, covering his tracks?
