Abstract
Official abstract text for this publication.
A biomass resource-derived 1,5-pentamethylene diamine produces a polyamide resin composition having a good color tone. The 1,5-pentamethylene diamine in which a total of the contents of an acetamide, 2,3,4,5-tetrahydropyridine, 2-piperidone, α-amino-ε-caprolactam, lysine and ornithine that the 1,5-pentamethylene diamine contains as impurities is less than or equal to 150 weight ppm.

1 - 4 . (canceled) 5 . A 1,5-pentamethylene diamine having a total content of acetamide, 2,3,4,5-tetrahydropyridine, 2-piperidone, α-amino-ε-caprolactam, lysine and ornithine contained as impurities less than or equal to 150 weight ppm. 6 . The 1,5-pentamethylene diamine according to claim 5 , wherein the content of the acetamide is less than or equal to 70 weight ppm. 7 . The 1,5-pentamethylene diamine according to claim 5 , produced by a biomass resource-derived lysine. 8 . A method of producing the 1,5-pentamethylene diamine according to claim 5 , comprising rectifying the 1,5-pentamethylene diamine at a temperature greater than or equal to 40° C. and less than or equal to 200° C. and a pressure greater than or equal to 0.2 kPa and less than or equal to 1200 kPa and with a theoretical plate number greater than or equal to 5. 9 . The 1,5-pentamethylene diamine according to claim 6 , produced by a biomass resource-derived lysine. 10 . A method of producing the 1,5-pentamethylene diamine according to claim 6 , comprising rectifying the 1,5-pentamethylene diamine at a temperature greater than or equal to 40° C. and less than or equal to 200° C. and a pressure greater than or equal to 0.2 kPa and less than or equal to 1200 kPa and with a theoretical plate number greater than or equal to 5. 11 . A method of producing the 1,5-pentamethylene diamine according to claim 7 , comprising rectifying the 1,5-pentamethylene diamine at a temperature greater than or equal to 40° C. and less than or equal to 200° C. and a pressure greater than or equal to 0.2 kPa and less than or equal to 1200 kPa and with a theoretical plate number greater than or equal to 5.
