| Use | methacrylamide is a weight gain improver after silk degumming and before dyeing and finishing. Because the pigment, fat, wax and other impurities are removed from the raw silk during degumming, there is a weight loss of 20-30% of the degumming amount, it can not only make up for the weight loss of white factory silk caused by degumming, but also can obviously improve the appearance of white factory silk and improve the application effect of silk fabric. Graft polymerization of methacrylamide in elastic exterior wall coatings and raw silk industry. methacrylamide is an intermediate for the production of methyl methacrylate. organic synthesis. Synthesis of polymer compounds. |
| production method | sodium cyanide is used as raw material to react with sulfuric acid to prepare hydrocyanic acid, which reacts with acetone to generate acetone cyanohydrin, it is reacted with concentrated sulfuric acid to form methacrylamide sulfate, and then neutralized with ammonia water to obtain finished methacrylamide. Hydrogen cyanide was prepared by the reaction of sodium cyanide with sulfuric acid. Methacrylamide sulfate is prepared from hydrocyanic acid, and the production method is the same as that of methacrylic acid. The obtained methacrylamide sulfate is neutralized with ammonia, extracted, crystallized, filtered and dried at low temperature to obtain a finished product. Production of methacrylamide with sodium cyanide as raw material, consumption of 821kg of sodium cyanide, acetone (≥ 98.5%)883kg, sulfuric acid 3440kg, liquid ammonia 650kg per ton of product. |
