Application	1-methyl-1-ethylpyrrolidine bromide is a quaternary ammonium salt. As an important chemical raw material, quaternary ammonium salt is widely used in various fields such as chemistry and chemical industry and shows a growing trend, especially as electrolyte and quaternization reagent, its dosage and quality requirements are also increasing. The production of quaternary ammonium salts is generally obtained by an alkylation reaction, and can also be obtained by replacing an anion of an existing quaternary ammonium salt.
preparation	a process for synthesizing quaternary ammonium salt, comprising the following steps, the raw material and solvent metering valves are respectively opened, and raw material A, raw material B and solvent are added to the reaction kettle; Wherein, raw material A is N-methyl-pyrrolidine; Raw material B is bromoethane; And solvent is acetone; according to the parts by weight, the amount of raw material A is 1 part, the amount of raw material B is 1 part, and the amount of solvent is 5 parts; S2, start heating, when the temperature in the reactor reaches the set temperature of 35 ℃, stop heating; Control the inlet cut-off valve of the condenser so that the pressure in the reactor reaches the set pressure of 30kPa; Start the reaction and control the metering valve of the raw material B, adjust the amount of raw material B, and then control the temperature in the reactor; Control the condenser outlet cut-off valve, the raw material B condensation reflux; S3, reach the Reaction Time 1h after the end of the reaction, close the inlet condenser cut-off valve, the surface pressure in the reaction kettle is controlled to be 30kPa, and the reaction liquid enters the reaction liquid storage tank to complete the solid-liquid separation through the steam pressure; The solid product is discharged directly, and the liquid is recycled. The yield of the obtained product was 95.47%, and the conversion of the raw material was 99.5%.
