QUATERNARY AMMONIUM SALTS OF THE FORMULA Z(+)-CH(-R'')-O-R-SI(-Q)(-Q'')-Q" X(-) WHERE Q, Q'' AND Q" ARE HYDROGEN, HALOGEN, HYDROXYL, MONOVALENT HYDROCARBON AND HALOHYDROCARBON RADICALS THAT ARE FREE OF ALIPHATIC UNSATURATION, $O-, $COO-, $2C=N-O, $=C=N-O- OR R"O(CH2CH2O)M-, $ IS HYDROCARBON OR HALOHYDROCARBON RADICALS, R" IS AN ALKYL, M IS 1 TO 2, R IS DIVALENT ALIPHATIC OR CYCLOALIPHATIC HYDROCARBON RADICALS, R'' IS HYDROGEN OR MONOVALENT HYDROCARBON RADICALS, Z IS A TERTIARY AMINE RADICAL, AND X IS A HALOGEN ATOMS AS DISCLOSED. AN EXAMPLE OF A QUATERNARY AMMONIUM SALT IS 1-(CH3-SI(-CL)2-(CH2)3-O-CH2-)PYRIDINIUM X(-) THE QUATERNARY AMMONIUM SALTS ARE USEFUL AS WATER REPELLENTS AND AS INTERMEDIATES IN MAKING SILOXANES WHICH ARE USEFUL AS WATER REPELLENTS ESPECIALLY FOR CELLULOSIC FABRICS. |
