Изобретение относится к области химической технологии, точнее к способам получения незамещенных амидов карбоновых кислот, в частности к способу получения формамида. Предложен способ получения формамида путем взаимодействия муравьиной кислоты и аммиака при 30 - 110oС в присутствии добавок воды, взятых в массовом соотношении вода : кислота 1 : 1 - 20 с последующим разложением образующегося формиата аммония при 150 - 180oС в присутствии аммиака, взятого в молярном соотношении кислота : аммиак 1 : 0,1 - 1.The invention relates to the field of chemical technology, more specifically to methods for producing unsubstituted amides of carboxylic acids, in particular to a method for producing formamide. A method for producing formamide by reacting formic acid and ammonia at 30-110 ° C in the presence of water additives taken in a mass ratio of water: acid 1: 1-20, followed by decomposition of the formed ammonium formate at 150-180 ° C in the presence of ammonia taken in a molar ratio acid: ammonia 1: 0.1 - 1.
