Abstract
PURPOSE: To obtain the titled compound smoothly and efficiently useful as a raw material for high polymers and intermediate material for organic synthetis, by hydrolyzing a specific lactam, its oligomer, or its polymer through ring opening in the presence of water and lithium carbonate.
CONSTITUTION: A 5W13 membered ring lactam (e.g., α-pyrrolidone, etc.), its oligomer, or its polymer through ring opening, is hydrolyzed in the presence of water and lithium carbonate at 60W350°C to give an ω-aminoalkanecarboxylic acid (ACA). An amount of lithium carbonate is preferably at least half the molar quantity of the law material lactam and water in an amount about equimolar with the lactam is required.
EFFECT: ACA can be obtained by an extremely simple operation without using a strong acid or strong alkali at all. Since lithium carbonate is used in circulation, no byproduct is prepared.
