실험 절차

494 kg (5606 mol) of ethyl acetate and 244 kg (1000 mol) of 1,6-dibromohexane were charged into a reactor with stirring and simultaneous heating to 60° C. 64 kg (1080 mol) of trimethylamine were metered in at 1 bar in the course of 3 hours. After an after-reaction time of a further 3 h, the reaction mixture was cooled and filtered through a suction filter and the crystallizate obtained was washed with ethyl acetate. After drying had taken place, 288 kg (95.1%) of (6-bromohexyl)trimethylammonium bromide of 99.8% purity were obtained.
