Industrialized synthesis method for reducing blue 6 (by machine translation)

The method, comprises the following steps 6: reducing a blue, solid into an aromatic inert solvent: to obtain a reduced blue 4 solution or suspension, adding a base adjusting reaction solution 4 to a; value of 4 discharge, to obtain a reduced blue 20-40 °C; solution or suspension . The solvent can be further ensured; by heating the solvent after completion of, heating reaction, and adding an alkali adjusting reaction liquid pH to the reaction solution after the reaction is finished 7-10; after completion of the solvent distillation pH and adding the alkali adjusting reaction solution, 6 and adding a base adjusting reagent 6, to the reaction solution 5-8 after, the completion of the . solvent distillation is finished, and adding a base adjusting reaction liquid. ?1.0.0.0.0.0.0.0.6.6.0-sup sup 10 beta pH 10 sup.
