摘要： This invention relates to preparing formamide compounds in a process which comprises reacting an amine with a formylalkanolamine in the presence of carbon monoxide in which the mole ratio of amine to formylalkanolamine ranges from 0.2:1 to 5:1. The reaction is conducted at a temperature ranging from about 50.degree. to 300.degree. C. and a pressure ranging from about 100 to 10,000 psig. The amine employed in the reaction has the formula: ##STR1## wherein R' is hydrogen, an alkyl group of 1 to 10 carbon atoms, cyclohexyl, or --R"--O--R'", wherein R" is a divalent alkylene group of 2 to 4 carbon atoms and R'" is an alkyl group of 1 to 3 carbon atoms; and R is hydrogen or an alkyl group of 1 to 10 carbon atoms. The formylalkanolamine employed in the reaction has the formula: ##STR2## wherein R is an alkylene group of 1 to 3 carbon atoms, z is 0 or 1 and y is 1 or 2 and the sum of y and z is 2.
