摘要： A process for the prevention of the growth of microorganisms, especially in industrial water, comprises contacting these microorganisms with an effective antimicrobial amount of a reaction product of Epsilon -caprolactam and an N-alkylalkylene diamine with the reaction being carried out in the liquid phase for 3 to 20 hours at a temperature above 180*C. The process further comprises incorporating into said industrial water an effective amount of a sequestering agent comprising a watersoluble phosphonic acid which forms a complex with a divalent metal, a water-soluble salt of the acid and the mixtures thereof, with the weight ratio of sequestering agent to reaction product being 1:10 to 10:1.
