Synthesis process of dialkyl dimethyl ammonium chloride

The invention discloses a synthesis process of dialkyl dimethyl ammonium halide, which comprises the following steps: mixing primary alkyl halide R1X and long-chain alkyl dimethylamine R2(CH3)2N, heating to 130-150 DEG C in a closed container, keeping the temperature to react for 4-6 hours, cooling, and diluting with an ethanol water solution to obtain dialkyl dimethyl ammonium halide, wherein thereaction temperature is determined by the number of carbon atoms of R1 and R2, and the formula is 130 DEG C+2.5(CR1+CR216)DEG C. Primary alkyl halide and long-chain alkyl dimethylamine directly reactto generate dialkyl dimethyl ammonium halide, so that the use of flammable and combustible gaseous raw materials is avoided, and the production safety is improved, the production process flow and equipment are simple, the production cost is low, industrial popularization is facilitated, no acid or salt byproduct is generated, and the product is high in purity, free of three wastes and environmentally friendly.
