| uses | tryptopol AS-BS is mainly used as a cotton-dyed red primer, which is matched with a red base R to obtain rose red, and with a red base G to obtain a gorgeous pink with blue light. It can also be mixed with tryptopol AS or tryptopol AS-OL, and then matched with big red base G to obtain a very red color. It can also be used to dye vinylon, viscose fiber, silk, and to make fast pigments and neutrals. It is mainly used as a primer for dyeing and printing of cotton fabrics. It is generally used together with tryptopol AS, showing red, rose red and other colors. It can be used as an intermediate for fast pigments and organic pigments. The organic pigment toluidine purplish red can be prepared from chromophenol AS-BS. Mainly used as printing and dyeing primer for cotton fabrics, and used to make fast pigments |
| production method | the raw material is heated and dehydrated by chlorobenzene, in the presence of phosphorus trichloride and chlorobenzene, 2,3-acid and m-nitroaniline Condensation, then neutralize with sodium carbonate, and evaporate chlorobenzene, and then filter and dry to obtain. Raw material consumption (kg/t)2,3-acid 670 m-nitroaniline 530 phosphorus trichloride 220 chlorobenzene 170 sodium carbonate 170 Using 2,3-acid and m-nitroaniline as raw materials, 2,3-acid is first made into sodium salt in chlorobenzene medium, then condensed with m-nitroaniline in the presence of PCl3, neutralized, distilled, filtered, and dried to obtain the finished product.. |
