A process is proposed for production of formamides by reaction of carbon dioxide with hydrogen in a hydrogenation reactor I in the presence of
a catalyst comprising an element from group 8, 9 or 10 of the periodic table,
a tertiary amine comprising at least 6 carbon atoms per molecule, and also
a polar solvent,
to form formic acid-amine adducts as intermediates, which are subsequently reacted with ammonia or amines in a reactor to obtain a two-phase liquid reaction effluent from which the liquid phase enriched with the formamides is distillatively separated to recover the formamide.
提议了一种生产甲酰胺的过程,通过在氢化反应器I中将
二氧化碳与氢在存在来自周期表第8、9或10族元素的催化剂、每分子至少含有6个碳原子的三级胺和极性溶剂的情况下反应,形成
甲酸胺加合物作为中间体,随后在反应器中与
氨或胺反应,以获得含有甲酰胺的液相反应产物,从中通过蒸馏分离液相富集的甲酰胺以回收甲酰胺。
