ABSTRACT:
Active microbiocides prepared by reacting a long-chain N alkyl diamine such as cocodiamine in molar amounts with 0.5-3.0 moles of epichlorohydrin under controlled conditions and then terminating the active end groups by reacting with 0.5-3.0 moles of a tri lower alkylamine, such as trimethylamine. The poly quaternary nitrogen compounds produced are effective at 25 ppm levels in recirculating systems against bacteria, such as A. aerogenes. In inhibition tests these compounds have also proved effective against fungi, such as A. niger.
