摘要： 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.
