Abstract

PURPOSE:To obtain the title compound useful as an intermediate for the synthesis of high polymers in high yield readily in a short time, by dry distillation of epsilon-caprolactam, its ring opening polymer, or epsilon-aminocaproic acid in the presence of LiOH in a specific temperature range. CONSTITUTION:epsilon-Caprolactam, its ring opening polymer nylon 6, or epsilon-aminocaproic acid is dried up by distillation in the presence of LiOH(a strong basic decarboxylating agent) at 300-400 deg.C while distilling the reaction product amino- Schiff base. The LiOH is used in a molar amount of 1 to 2.5 times that of carbonyl groups in the raw material, and preferably monohydrate. USE:An intermediate of raw materials, e.g. alpha, omega-undecamethylenediamine, for the synthesis of high polymers.
