METHOD FOR PRODUCING N-SUBSTITUTED (METH)ACRYLIC AMIDE

Japanese Patent JP2016074620

A

PROBLEM TO BE SOLVED: To provide a method for simply and inexpensively producing an N-substituted (meth)acrylic amide without need of heat treatment for decomposing a Michael adduct by-produced in an amidation reaction of an ester nor protection-deprotection treatment of a double bond and to provide a method for producing an N-substituted (meth)acrylic amide-containing polymer.SOLUTION: The method for producing an N-substituted (meth)acrylic amide includes reacting a (meth)acrylic acid ester represented by Formula (1) with an amine represented by Formula (2) in the presence of a catalyst while maintaining a temperature of a reaction mixture at 50°C or lower to produce an N-substituted (meth)acrylic amide represented by Formula (3). Formula (1): CH=CRCOOR(R is a hydrogen atom or a methyl group; and Ris a lower alkyl group; Formula (2): R-NH-R(Rand Rare each independently a hydrogen atom, an alkyl group or an alkyl group having a substituent); and Formula (3):CH=CRCON(R)-R(R is the same as that in Formula (1); and Rand Rare the same as those in Formula (2))SELECTED DRAWING: None
