Brief introduction
Formamide is an important organic solvent and organic chemical raw material used mainly for pharmaceutical intermediates, fragrances, dyes, paper conditioning agent, fiber softening agent, and gelatin softener.
Technical features
Methyl formate obtained through methanol dehydrogenation takes a continuous amination reaction with liquid ammonia and, after dealcoholization and rectification of the reaction liquid, product formamide is obtained.
