Abstract
Abstract Quarternary ammonium compounds have the formula R 1 R 2 R 3 N + (CH 2 ) m Y X - wherein R 1 is an alkyl containing 8-20 carbon atoms, R 2 is an alkyl containing 8-20 carbon atoms or methyl or ethyl, R 3 is methyl or ethyl, m is an integer from 1-6, X is an anion and Y is a group having the structure --Z, --OH, --OR 4 , --OC(O)R 5 , --CN, --O--S(O)(O)--OQ, --C(O)OR 6 , --C═CH, --SR 7 , --S(O)(O)R 8 , --S(O)R 9 , --NR 10 R 11 and --CH═CH 2 wherein R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 are alkyls containing 1-12 carbon atoms or are phenyl and Z is halogen and Q is hydrogen or a cation having been found to be very effective bactericides.
