Abstract
This invention pertains to novel multiple quaternary ammonium salts and their derivatives represented by the formula:wherein each R1, R′1, R2, R′2, R3, R′3, R4 or R5 is independently selected from the group consisting alkyl, aryl, aralkyl and —CH2—CH(OR6)—CH2N+R1R2R3;wherein one or more R6 group is selected from the group consisting of:and wherein An− is an anion.This invention also pertains to novel multiple quaternary ammonium salts and their derivatives represented by the formula:wherein each R1, R′1, R2, R′2, R3 or R′3 group is independently selected from the group consisting of alkyl, aryl, aralkyl and —CH2—CH(OR4)—CH2N+R1R2R3;wherein one or more R4 group is selected from the group consisting of:and wherein An− is an anion.
