Reaction Conditions

Reaction Steps

The following are added successively at room temperature with stirring to a flask of contents 1 dm3 which is equipped with a stirrer, a reflux condenser and a contact thermometer and is surrounded at its bottom by an electrically heatable jacket which is controlled by the contact thermometer: 145.3 g (0.6 mol) of N-tetradecyl-N,N-dimethylamine, 249.3 g (6.07 mol) of acetonitrile and 104.0 g (0.63 mol) of 1-bromohexane. While stirring is continued, the mixture is heated to a temperature of 85° C. and kept at this temperature for 4 hours, then it is cooled to room temperature, a sample is taken and the residual amine content in this is determined. On the basis of this determination, the amine conversion is 99%. The contents of the flask are then added to a rotary evaporator and the liquid constituents, essentially acetonitrile, are distilled off in a water bath at a temperature rising from 50° to 80° C. and a pressure falling from 9.6 to 1.8 kPa at 320 revolutions per minute during the course of 4 hours. The N-tetradecyl-N-hexyl-N,N-dimethylammonium bromide (1) thus obtained is then dried at room temperature under a pressure of 40 Pa generated by an oil vacuum pump and used for the viscosity determinations described below. The product is analysed, the following values being determined:
