Abstract
Quarternary ammonium compounds have the formula R.sup.1 R.sup.2 R.sup.3 N.sup.+ (CH.sub.2).sub.m Y X.sup.- wherein R.sup.1 is an alkyl containing 8-20 carbon atoms, R.sup.2 is an alkyl containing 8-20 carbon atoms or methyl or ethyl, R.sup.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.sup.4, --OC(O)R.sup.5, --CN, --O--S(O)(O)--OQ, --C(O)OR.sup.6, --C.dbd.CH, --SR.sup.7, --S(O)(O)R.sup.8, --S(O)R.sup.9, --NR.sup.10 R.sup.11 and --CH.dbd.CH.sub.2 wherein R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9, R.sup.10, R.sup.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.
Claims9
