So this means that the hydroxy group can only move around when it is next ... 4-11-2008 at 18:02 by: Baphomet Chromatography materials Thanks for the information guys! Good point about reproducability, Klute. I will mostly be using TLC ... 2-11-2008 at 19:52 by: Baphomet Isomerisation of alcohols This may be a dumb question.. How can one determine if an alcohol is prone to spontaneous isomeri ... 2-11-2008 at 17:17 by: Baphomet Chromatography materials - If I make silica by adding HCl to waterglass, and then roasting and grinding the silica, will it b ... 2-11-2008 at 16:38 by: Baphomet Replacement of GAA in bleach oxidations Oops, the byproduct would be HCl. That explains the buffering then.. 31-10-2008 at 20:37 by: Baphomet Replacement of GAA in bleach oxidations There is an American patent related to the method specified by Nicodem: http://www.patentstorm.us/p ... 31-10-2008 at 20:15 by: Baphomet Replacement of GAA in bleach oxidations That sounds like a good synthesis. I might try it myself! Interesting that you mention the o-chlo ... 29-10-2008 at 04:18 by: Baphomet Replacement of GAA in bleach oxidations Regarding phosphoric acid, it can be deprotonated more than once and it's pKa is lower than acetic a ... 29-10-2008 at 03:24 by: Baphomet The short questions thread (1) Regarding GAA, has anyone tried gassing Sodium Acetate with dried HCl instead of mixing with aqueous ... 28-10-2008 at 22:55 by: Baphomet Oxidation of a phenolic derivative with ammonium persulfate What can I say? Some people get mole envy. 16-10-2008 at 17:58 by: Baphomet Oxidation of a phenolic derivative with ammonium persulfate Thanks chemeleo. That makes sense. Especially in light of the fact that the persulfate radical wants ... 16-10-2008 at 15:40 by: Baphomet Oxidation of a phenolic derivative with ammonium persulfate I have no problem with people answering my questions.
