use	pharmaceutical intermediates.
Production method	It is prepared by the reaction of 2-amino-5-chlorobenzophenone and hydroxylamine hydrochloride. The -2-amino -5-chlorobenzophenone reactant obtained by ring-opening and reduction of isoxazole is added with liquid alkali to adjust the pH to 8, then activated carbon is added to reflux for 30min, and filtered while hot. The filtrate was refluxed with hydroxylamine hydrochloride for 10h. After ethanol (75%) is recovered, water is added to dilute the ethanol concentration to 4-5%. Cold to 30 ℃, add sodium carbonate saturated solution to pH9. Filter and wash the cake with hot water until neutral. Filter dry, dry below 80 ℃ to obtain 2-amino -5-chlorobenzophenone oxime.
