Method for preparaing formamide compound

Abstract

The present disclosure provides a method for preparing a formamide compound. The method for preparing the formamide compound includes providing a reaction solution, exposing the reaction solution to a reaction pressure in a reaction gas and under a reaction temperature for a reaction time so as to form a mixed solution, and purifying the mixed solution so as to obtain the formamide compound. The reaction solution includes an amine compound, an aldehyde compound and a solvent. Therefore, it is favorable for increasing a yield rate of the formamide compound, and reducing the waste amount of the useless solvent and by-product.
