, (2018/11/27)
The invention discloses fluopyram and a synthesis method thereof. The fluopyram comprises the following raw materials: trifluoromethylbenzoic acid, thionyl chloride, ammonia water, water, potassium carbonate, paraformaldehyde, formamide, acetic anhydride, 5-trifluoromethyl-2-dimethyl malonate--3-chloropyridine, sodium chloride and hydrochloric acid. The content of fluopyram obtained in the invention is 98% or more, and the total yield of fluopyram is 63% or more. The synthesis method of the invention does not use cyano groups with high activity, and the yield of aminolysis can reach 93%; the raw materials are simple to treat and high in utilization rate; waste gas, waste water and industrial residues are not produced; and the synthesis method is simple in process and easy to operate and implement.
