Reaction Steps
About 125 parts 1,4-dichlorobutene-2 and 60 parts trimethylamine are mixed with 700 parts 2-hexanone in a stainless steel pressure reactor. The mixture is allowed to react for 5 hours at a temperature of about 75°C. to about 80°C. Next, 60 parts of water are added to the cooled reaction mixture. This mixture yields about 93.5% 4-chloro-2-butenyltrimethylammonium chloride. The 2-hexanone is removed either by vacuum distillation or separated by decantation from the reaction mixture. About 95% of the 2-hexanone is recovered for reuse.
