METHOD FOR PRODUCING N-(ALPHA-HYDROXYETHYL)FORMAMIDE AND METHOD FOR PRODUCING N-VINYLFORMAMIDE

A method for producing N-(α-hydroxyethyl)formamide which comprises reacting formamide with acetaldehyde in a solvent in the presence of a basic catalyst in a reaction vessel, precipitating the obtained N-(α-hydroxyethyl)formamide in the reaction vessel, and collecting the precipitated N-(α-hydroxyet...

Zusammenfassung:A method for producing N-(α-hydroxyethyl)formamide which comprises reacting formamide with acetaldehyde in a solvent in the presence of a basic catalyst in a reaction vessel, precipitating the obtained N-(α-hydroxyethyl)formamide in the reaction vessel, and collecting the precipitated N-(α-hydroxyethyl)formamide from the reaction vessel. The production of N-(α-hydroxyethyl)formamide is conducted multiple times using the same reaction vessel so that an (n+1)th reaction is conducted in the reaction vessel in which crystals of the N-(α-hydroxyethyl)formamide obtained in the n-th reaction are present (n is a natural number).
