Process for the preparation of a mixture of 3-chloro-anthranilic acid alkyl ester and 6-chloro-anthranilic acid alkyl ester |
| abstract |
Preparation of a mixture of 3-chloroanthranilic acid alkyl ester and 6-chloroanthranilic acid alkyl ester in a certain molar ratio of the components by a) reacting 3-chlorophthalic anhydride with ammonia, alkali metal hydroxide and alkali metal hypochlorite or b) reacting 3-chlorophthalic acid anhydride to 3-chlorophthalamide and alkali metal chloride with alkali metal chloride and alkali metal chloride followed by reaction with alkali metal chloride and alkali metal chloride with subsequent reaction with alkali metal chloride and finally esterification of the mixture of 5-chloroisatoic anhydride and 8-chloroisatoic anhydride obtained according to a) or b) with alkanols.n n n The compounds which can be prepared by the process of the invention are valuable starting materials for the production of dyes, crop protection agents and fragrances. |
