摘要

The invention relates to bisquaternary ammonium compounds of the formula (I) <IMG> (I) and their preparation, where: R1, R2, R3 are, for example, identical or different (C1C12)alkyl which can also contain oxygen atoms or N-R4 moieties, where R4 is (C1-C4)alkyl, in the chain and A is a chlorine, bromine, iodine atom or a OSO3R5 radical, where R5 is (C1-C4)alkyl or aryl.
