Abstract

The present application provides a preparation method of a formamide compound, the preparation process includes: uniformly mixing raw material of methanoic acid and an amine compound selected from a primary amine or a secondary amine to prepare a homogeneous reaction system; the above homogeneous reaction system is heated to 160-230° C., allowing carbon monoxide to be decomposed from the homogeneous reaction system and participates in the reaction, and collecting the reaction product to obtain a formamide compound. The present application provides a new technology using a homogeneous method to synthesize a formamide compound, the reaction process needs no use of a catalyst, the operation process is simple and controllable, and the raw material of the amine compound has a high selectivity.
