2-Hydroxy-3-Naphthoyl-O-Anisidine - Reference Information

chemical properties rice brown powder. Soluble in ethanol. The solution dissolved in caustic soda is fluorescent yellow. Insoluble in water, slightly soluble in soda ash solution.
use tryptopol AS-OL is mainly used for cotton dyeing. its performance is similar to that of tryptopol AS. it can be used in combination and can improve dyeing fastness. It is also used for dyeing vinylon, viscose fiber, silk, nylon and diacetate fiber. Used for cotton printing base, combined with different color bases to obtain orange, red, sauce, and blue colors. It is also used to make fast pigments, fast amines, fast sulfonates and lake pigments.
It is mainly used as a primer for dyeing and printing of cotton fabrics. It can also be used to make fast pigments and as an intermediate for organic pigments.
Mainly used in the production of insoluble dyes and for dyeing cotton fiber and viscose fiber
production method 2,3-acid is salted and dehydrated with chlorobenzene and sodium carbonate, then condensed with o-amino anisole in the presence of phosphorus trioxide, neutralized with sodium carbonate, evaporated chlorobenzene, and then filtered and dried to obtain the finished product. Raw material consumption (kg/t)2,3-acid 710 o-amino anisole 470 phosphorus trichloride 270 sodium carbonate (98%) 570 chlorobenzene (98%) 150 hydrosulfite 8
using 2,3-acid and o-methoxyaniline as raw materials, 2,3-acid is first prepared into sodium salt in chlorobenzene medium, then condensed with o-methoxyaniline in the presence of PCl3, neutralized, distilled, filtered and dried to obtain the finished product..
