Abstract
1320633 Alpha-hydroxy ketones CHEM SYSTEMS Inc 3 Sept 1971 [8 Sept 1970] 41211/71 Heading C2C Alpha hydroxy ketones are prepared by chlorinating a ketone having an alpha hydrogen atom and from 4 to 15 carbon atoms in the liquid phase in the presence of a solvent at 0‹ to 100‹ C., thereby forming a reaction product containing an alpha-chloro ketone and unreacted ketone and hydrolysing the alpha-chloro ketone in the presence of an alkaline material prior to or during the separation of the unreacted ketone. The ketone may by a cyclic ketone having from 5 to 12 ring carbon atoms. The chlorination reaction product may be hydrolysed in an aqueous solution containing an ammonium or alkali metal carbonate or bicarbonate. The chlorination may be carried out in an organic solvent capable of dissolving the ketone or in the presence of water.
