1, 5-PENTAMETHYLENE DIAMINE AND METHOD FOR PRODUCING SAME

摘要

A biomass resource-derived 1,5-pentamethylene diamine that gives a polyamide resin composition having a good color tone and a production method therefor are provided. A 1,5-pentamethylene diamine in which a total of the contents of acetamide, 2,3,4,5-tetrahydropyridine, 2-piperidone, ±-amino-µ-caprolactam, lysine, and ornithine that the 1,5-pentamethylene diamine contains as impurities is less than or equal to 150 weight ppm is made.
