Methacrylamide Use and Manufacturing

Methods of Manufacturing

Sodium cyanide is used as raw material to react with sulfuric acid to obtain hydrocyanic acid. Hydrocyanic acid reacts with acetone to generate acetone cyanohydrin, and then reacts with concentrated sulfuric acid to generate methacrylamide sulfate, which is then neutralized with ammonia to obtain product formaldehyde. Base acrylamide. Sodium cyanide reacts with sulfuric acid to obtain hydrocyanic acid. The 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. To produce methacrylamide with sodium cyanide as raw material, 821kg sodium cyanide, 883kg acetone (≥98.5%), 3440kg sulfuric acid and 650kg liquid ammonia are consumed per ton of product.

Uses

Organic Synthesis. Synthesis of polymer compounds.
