Reaction Conditions

Reaction Steps

The procedure is as described in Example 1, but the following are added successively to the flask with stirring: 157.4 g (0.65 mol) of N-tetradecyl-N,N-dimethylamine, 240.0 g (5.85 mol) of acetonitrile and 82.6 g (0.683 mol) of allyl bromide. The contents of the flask warm up without external heating to 61° C. in the course of 20 minutes. The flask is then heated again to 70° C. by means of the external heating and kept at this temperature with stirring for 1 hour and then cooled to room temperature, and an amine conversion of 99.7% is determined in a sample of the contents of the flask by a residual amine determination. Working-up is carried out as described in Example 1. The N-tetradecyl-N-allyl-N,N-dimethylammonium bromide (3) thus obtained is used for the viscosity determinations described below. The following contents are determined analytically:
