Abstract

PURPOSE: To obtain the titled compound useful as a raw material for preparing an ω-aminoalkanecarboxylic acid, etc. effectively, by hydrolyzing a lactam in the presence of water and a carbonate of Li, Ca, etc. under heating, and discharging CO2 which is emitted.
CONSTITUTION: A lactam(5W13 membered ring lactam, its oligomer, or its polymer through ring opening) is hydrolyzed in the presence of water and a carbonate of a metal selected from Li, Ca, and Ba at 60W350°C, and CO2 which is emitted is discharged to give the titled compound. Lithium carbonate is especially preferably as the metallic carbonate.
EFFECT: A raw material, a lactam, which is not high quality, can be used, and a recovered lactam in the production of polyamide is sufficient. A metallic carbonate prepared as a byproduct in the production of an ω-aminoalkanecarboxylic acid or amino Schiff base from the titled compound can used in circulation.
