Embodiment 1
[0024] A kind of benzalkonium chloride monomer synthesis technique, comprises the steps:
[0025] (1) Measure dodecyldimethyl tertiary amine, benzyl chloride and ethyl acetate respectively according to the formula, and the molar mass ratio of said dodecyl dimethyl tertiary amine and benzyl chloride is 1:1;
[0026] (2) Put ethyl acetate into a 300L glass-lined reaction kettle, pump dodecyldimethyl tertiary amine and benzyl chloride into the head tank respectively, turn on the stirring device of the reaction kettle, and Methyl tertiary amine and benzyl chloride are dropped into the reactor in the same proportion;
[0027] (3) Turn on the heating device, raise the temperature of the reactor to 85°C, and keep it warm for 10 hours;
[0028] (4) Turn on the circulating cooling water and cool the product to room temperature until the crystals are completely precipitated;
[0029] (5) Take out the precipitated crystals, filter under reduced pressure, wash the crystals with ethyl ac...
