this product is in the form of beige powder with a melting point of 243-244°c. it is soluble in chlorobenzene, insoluble in water and soda ash solution, and turns yellow in sodium hydroxide solution.
storage method
none
synthesis method
first, 2,3-acid is salted with sodium hydroxide and chlorobenzene, and then condensed with tobaic acid and phosphorus trichloride, and then hydrolyzed, neutralized and post-treated with sodium dihydrogen phosphate to obtain the finished product. raw material consumption (kg/t) 2,3-acid (100%) 750 toburic acid (100%) 900 phosphorus trichloride (100%) 230 soda ash (98%) 388 chlorobenzene (98%) 410
purpose
mainly used as primer for dyeing and printing cotton fabrics. and can be used instead of chromic acid as.
