new umsetzungsprodukte of epsiloncaprolactam with alkandiaminen

摘要

Reaction products of epsilon -caprolactam with N-alkylalkylene diamines of the formula WHEREIN R denotes a straight- or branch-chained, saturated or unsaturated aliphatic hydrocarbon substituent with 10 to 18 carbon atoms, R1 denotes hydrogen or an aliphatic hydrocarbon substituent with 1 to 4 carbon atoms, where n is an integer of from 2 to 6, preferably 3, and where the molar ratio of the reaction partners N-alkylalkylene diamine: epsilon -caprolactam is 1:1 to 1:10, and the reaction is carried out for 3 to 20 hours in the liquid phase at temperatures above 180 DEG C, preferably at about 250 DEG C. These reaction products are useful in compositions to prevent the growth of microorganisms, such as bacteria, fungi and algae.
