DMF是优良的有机溶剂和重要的化工原料。可广泛用作聚氨酯、聚丙烯腈和聚氯乙烯等具有强大分子引力的聚合物的溶剂。在医药中用于合成磺胺嘧啶、可的松和维生素B6等。农药中用于合成杀虫脒等。在石油化工中用于抽提丁二烯等组分。一、DMF的生产方法及国内外生产情况1、甲酸酯化二步法先由甲酸与甲醇酯化生成甲酸甲酯,再将甲酸
DMF is an excellent organic solvent and an important chemical raw material. It can be widely used as a solvent for polymers with strong molecular attraction, such as polyurethane, polyacrylonitrile and polyvinyl chloride. It is used in the synthesis of sulfadiazine, cortisone and vitamin B6. Pesticides are used to synthesize insecticidal cockroaches. Used in petrochemicals to extract butadiene and other components. First, the DMF production methods and domestic and foreign production conditions 1, formic esterification of two-step method for the first esterification of formic acid and methanol to produce methyl formate, and then formic acid
