Title: PROCESS FOR PRODUCTION OF AROMATIC ALDOXIMES
Abstract:
A process for preparing an aromatic aldoxine, such as benzaldehyde oxime, by reacting the corresponding α.α-dihalide, such as benzal chloride, with a hydroxylamine salt in the presence of an excess of an aqueous base sufficient to maintain the product oxime in solution. Organic impurities may be phase separated from the reaction mixture. Thereafter, the aqueous solution containing product oxime is neutralized to separate an oxime phase, which may be recovered by decanting or solvent extraction.
