Steps:

1; 2; 3; 4 Example 3 A method for preparing dimethylcarbamoyl chloride, using a microreactor as a reaction device,The dimethylamine and phosgene are simultaneously introduced into the microreactor to carry out a reaction to obtain dimethylcarbamoyl chloride. Includes the following steps:

A microreactor with 8 reaction templates is used as a reaction device, wherein each reaction module in the microreactorThe temperature is controlled at 200 °C. 136.4 g of dimethylamine (99.0%, by gas mass flow meter at a rate of 27.3 g/min3.0 mol) was passed into the microreactor while 371.3 g of phosgene (80%, 3.0 mol) was passed into the microreverse at a rate of 74.3 g/min.In the reactor, mixing and reacting; after the reaction is completed, the obtained gas material is cooled to room temperature by a cooling device, and condensed.The cooled liquid material was collected to obtain 326.7 g of crude dimethylcarbamoyl chloride; after rectification, 313.4 g of dimethylaminomethyl was obtained.The acid chloride product, wherein the dimethylcarbamoyl chloride content was 99.0%, and the yield was 96.2% (based on dimethylamine).
