Reaction Steps

A three liter three-necked flask equipped with an addition funnel was charged with 583 grams (2.73 moles) of lauryl dimethyl amine, 330 grams of water and 330 grams of ethanol. With agitation, 133 grams (1.35 moles) of 37% hydrochloric acid was added to produce an equipmolar solution of lauryl dimethyl amine and lauryl dimethyl amine hydrochloride. The resulting exotherm brought the temperature to 60° C. 114.6 grams (1.24 moles) of epichlorohydrin was slowly added to the flask throught the addition funnel. The exothermic reaction brought the temperature of the contents of the flask to 71° C. The temperature of the reaction mixture was increased to 90° C. and maintained there for five hours.
