Procedure

An apparatus as described in Example 1 is used. The following are added successively to the flask with stirring: 164.8 g (0.6 mol) of N-hexadecyl-N,N-dimethylamine, 268.8 g (6.55 mol) of acetonitrile and 104.0 g (0.63 mol) of 1-bromohexane. The mixture is heated to 85° C. with stirring in the course of 4 hours and is then cooled to room temperature, and the residual amine content is determined in a sample and an amine conversion of 99.1% is determined from this. Working-up by means of a rotary evaporator and subsequent treatment in an oil pump vacuum is carried out as described in Example 1. The N-hexadecyl-N-hexyl-N,N-dimethylammonium bromide (2) thus obtained is used for the viscosity measurements described below. The following contents are determined analytically:
