Thiazolium, 3-methyl-2-[2-(1-methyl-2-phenyl-1H-indol-3-yl)diazenyl]-, chloride (1:1) Use and Manufacturing

Methods of Manufacturing

Using 2-aminothiazole and N-methyl-2-phenylindole as the main raw materials, first diazotize 2-aminothiazole with sodium nitrite and sulfuric acid at -5- -4℃, and then diazotize it with N-methyl -2-phenylindole is coupled, finally methylated with dimethyl sulfate, filtered, washed, and dried to obtain the finished product. . Add 408L of water, 330kg of sulfuric acid (93%) to the reaction pot, cool to 3°C, add 36kg of 2-aminothiazole (100%), continue to cool to -3- -4°C, add dropwise sodium nitrite solution (containing Sodium nitrate 30kg), add it within 1.5-2h, and keep it for 40min. Add 600L of water and 1.5t of ice to another reaction pot, and then suck in the above diazotized material, cool to 0-3℃, and slowly add the prepared N-methyl-2-phenylindole solution [from 300L of water , 6kg emulsifier OP, 69kg N-methyl-2-phenylindole and 555kg sulfuric acid (93%)], add it within 40-60min, and the reaction will reach the end. Then it was heated to 23°C and filtered. Add 75L of water and the above-mentioned dye matrix filter cake to the reaction pot, adjust the volume to 420L, add 27kg of magnesium oxide below 26°C, and add 57kg of dimethyl sulfate below 15°C, react at 33-35°C for 3h, and heat up to 90 ℃, adjust the volume to 2200L, filter at 60℃, salt out the filtrate, filter and dry to obtain the finished product.

Uses

Mainly used for dyeing acrylic loose fibers, fiber strips and acrylic fleece
