Use | phenol AS-SR is mainly used as a priming agent for dyeing black and purple, such as GGS, RC et al coupling gave a purple color. Mostly used for cotton, vinylon, viscose fiber dyeing, rarely used for cotton printing. This product has high affinity for cotton. It can also be used to make neutral. Its performance is similar to that of phenol AS-SG, so it can be mixed with each other. mainly used in the manufacture of organic pigments |
production method | with 2,3-acid, phenylhydrazine and 2-methyl-4-methoxyaniline as raw materials, first, the 2,3-acid is sulfonated with fuming sulfuric acid, alkali-melted, and then condensed with phenylhydrazine to close the ring. The product is then condensed with 2-methyl-4-methoxyaniline to form a salt with sodium carbonate. After the recovery of chlorobenzene by distillation after filtration, drying, grinding to get the finished product.. |
