The method of one kind chloro-5-chloromethyl-thiazole avoid pyrolysis

The present invention discloses a method of avoiding 2-chloro-5-chloromethyl-thiazole pyrolysis, relates to 2-chloro-5-chloromethyl-thiazole distillation art. 2-chloro-5-chloromethyl-thiazole was added crude epoxidized soybean oil, and then to distillation under reduced pressure, the early cut fraction, the fraction is 2-chloro-5-chloromethyl-thiazole finished; ring the amount of oxygen added to soybean oil 5-20% 2-chloro-5-chloromethyl-thiazole oxazole quality crude 5-chloromethyl-2-chloro-thiophene. The main advantage of the method of the present invention is to avoid pyrolysis of 2-chloro-5-chloromethyl-thiazole, to give 2-chloro-5-chloromethyl-thiazole high content of the finished product, greatly improving the high-temperature rectification process 2- chloro-5-chloromethyl-thiazole yield and quality of the finished product, reduces the production cost and improve economic efficiency.
