| titleOfInvention | Process for producing 4-methyl-3-nitrobenzenesulphonic acid and its soda salt |
| abstract | (57) [Summary] [Objective] In a method for sulfonating O-nitrotoluene, 4-methyl-3-nitrobenzenesulfonic acid and its soda salt, in which waste sulfuric acid is not discharged and unreacted O-nitrotoluene is not left, A method of manufacturing is provided. [Structure] O-nitrotoluene containing an inert gas SO The content of unreacted O-nitrotoluene and SO 3 is reduced by sulfonation with 3 gas and then aging. Then, the obtained reaction product is subjected to residual O- by any one of distillation in the presence of water and steam distillation. Remove nitrotoluene. Sulfuric acid is reduced to the extent that it does not interfere with the next reaction, and no particular purification is required. |
