Disperse yellow 231 synthetic method (by machine translation)

The invention discloses a disperse yellow 231 of the synthetic method, the concentrated sulfuric acid, nitrosyl sulfuric acid and phosphoric acid in the reactor, the opening stirring, frozen brine cooling to - 5 - 0 °C after, slowly adding to the amino benzoic acid benzyl ester, throws after thermal insulation reaction at the temperature for a period of time, made diazonium fluid; the N - butyl - 3 - cyano - 4 - methyl - 6 - hydroxy - 2 - pyridone and soft water added in the reactor and stir, then adding amino sulfonic acid, glacial acetic acid and lignin, temperature control in 0 °C following, at the same time dropping heavier gases and liquid caustic soda, dropping time control in the 2 - 3h, pH control in 5 ± 0.2, the completion of the dropping, after treatment to obtain the target product. The right amount of nitrosyl sulfuric acid and sulfuric acid substituted sodium nitrite and hydrochloric acid as a reducing agent to ensure the complete reaction of the raw material, and also to avoid the occurrence of diazonium fluid autoconnected and reaction, to ensure that the reaction smoothly diazonium fluid, the whole reaction process is rarely caused by tar, thus there is almost no solid waste of the environmental pressure.
