Method for producing arylpoly(oxalkyl)-benzyldimethyl-ammonium derivatives

   
   

The invention provides a process for preparing arylpoly(oxalkyl)benzyl-dimethylammonium derivatives of the formula (1) ##STR1## which comprises reacting compounds of the formulae (2) and (3) ##STR2## where X=Br, Cl, R--SO.sub.3 with R=alkyl, alkylaryl R.sub.1 =H, C.sub.1 - to C.sub.16 -alkyl or O--C.sub.1 - to O--C.sub.16 -alkyl in the ortho, meta or para position, R.sub.2 =H, C.sub.1 - to C.sub.4 -alkyl or O--C.sub.1 - to O--C.sub.4 -alkyl, R.sub.3 =H, C.sub.1 - to C.sub.16 -alkyl or O--C.sub.1 - to O--C.sub.16 -alkyl in the ortho, meta or para position, and n=1, 2, 3 or 4, at temperatures of from 60 to 160.degree. C. in a solvent under the autogenous pressure.
