N-(1-HYDROXYETHYL)CARBOXAMIDE COMPOUND AND PROCESS FOR PRODUCING SAME

The present invention relates to an N-(1-hydroxyethyl)carboxamidecompound represented by formula(1) (in the formula, RA and RB represent independently from each other a hydrogen atom or an alkyl group having 1 to 4 carbon atoms except for a case where RA and RB represent a hydrogen atom at the same time) and a method for producing the same; a method for producing an N-(1-alkoxyethyl)carboxamide compound; a method for producing an N-vinyl carboxylic acid amide compound; and a method for producing an N-vinyl carboxylic acid amide (co)polymer. An N- (1-alkoxyethyl) carboxamide compound can be obtained by reacting N-(1-hydroxyethyl)carboxamide compound with alcohol in the presence of an acid catalyst, and an N-vinyl carboxylic acid amide compound, which is a monomer of the N-vinyl carboxylic acid amide (co)polymer, can be obtained by thermally decomposing or catalytically decomposing the N-(1-alkoxyethyl)carboxamide compound.

Gas-phase vinylation of N-methylacetamide

Catalysts for selective gas-phase vinylation of N-methylacetamide with acetylene were studied. These catalysts were obtained by applying to wide-pore silica gel of the CdO-K2O-ZnO system or applying to commercial Al2O3 of the CdO-K2O and CdO-K2O-ZnO systems.

Catalyst for production of tertiary N-alkenyl carboxylic acid amide, and process for production of tertiary N-alkenyl carboxylic acid amide using said catalyst

The present invention provides a catalyst which is an oxide comprising silicon and at least one element selected from the group consisting of alkali metals and alkaline earth metals and which is used for gas-phase intramolecular dehydration of a tertiary N-(2-hydroxyalkyl) carboxylic acid amide to synthesize a tertiary N-alkenyl carboxylic acid amide. This catalyst enables continuous and efficient production of a tertiary N-alkenyl carboxylic acid amide from a tertiary N-(2-hydroxyalkyl) carboxylic acid amide without using any auxiliary raw material, and consequently allows for simple and safe production of a tertiary N-alkenyl carboxylic acid amide without generating any by-product (waste product) derived from the auxiliary raw material.
