| titleOfInvention | Improved process for the manufacture of 3-hydroxy-4-amino-phenyl-arsinic acid |
| abstract | 309,249. Balaban, I. E., and May & Baker, Ltd. Jan. 24, 1928. 3-Hydroxy-4-aminophenylarsinic acid is prepared by hydrolyzing 3-chloro-4-nitrophenylarsinic acid and reducing the resulting oxy-compound under mild conditions. The 3-chloro-4-nitrophenylarsinic acid is obtained in known manner from 3 chlor-4-nitraniline by diazotization fol. lowed by heat treatment with an arsenite such as copper arsenite. Examples are given of its hydrolysis with an alkaline hydroxide and the further reduction by means of glucose, sodium hydrosulphite or ferrous sulphate. |
