Abstract:
The present invention relates to a process for the production of a high yield solvent red 149 dye, comprising the steps of:(a) sequentially adding cyclohexylamine, 4 Bromo N methyl 9,10 anthracopyridinone and 1 butyl sulfonic acid 3 methyl imidazole hydrogen sulfate are stirred and dissolved to obtain a first mixture; (B) the first mixture is heated to 80~150 °c for reaction, the end point of the reaction was determined by HPLC detection; Then the temperature was cooled to 50~70 °c, methanol was added for isolation, and the filter cake and filtrate were obtained by Suction filtration;(c) the filter cake was washed with methanol, the washing liquid and the filtrate were collected and recovered by distillation. The filter cake was washed with hot water until neutral and dried. This accelerates the progress of the reaction to obtain Solvent Red 99.0% having a yield of 149 or more and having an extremely high purity.

Abstract:
The present invention relates to a process for the production of a solvent red 149 dye, comprising the steps of:(a) sequentially adding cyclohexylamine, 4 Bromo N methyl 9, the anthracopyridinone and the auxiliary agent are stirred and dissolved to obtain a first mixture; (B) the first mixture is heated to 80-150 ° C. For reaction, and the end point of the reaction is determined by HPLC detection; subsequently, the temperature is cooled to 50-70 ° c., and the isolation solvent is added for isolation; The temperature is further cooled for Suction filtration to obtain filter cake and filtrate;(c) the filter cake is washed with the isolation solvent, and the washing liquid and filtrate are collected, distillation recovery is performed; The filter cake is washed with hot water to neutral and dried. The obtained Solvent Red 149 dye Delta E<0.5, Delta C is approximately brilliant, the pressure value <0.2, the product quality can meet the application requirements of high-end customers.
