synthesis method
1. introduction to production methods
originated from the reaction of m-nitrobenzoic acid and phosgene. mix m-nitrobenzoic acid, benzene and a small amount of dimethylformamide and heat to 40-50℃ , to dissolve them all. then, phosgene is passed through until the acyl chloride is complete, and then nitrogen is introduced to drive away the remaining phosgene. distill the reaction product, recover the solvent benzene, and distill it twice under reduced pressure to obtain m-nitrobenzoyl chloride. in addition, m-benzoic acid and thionyl chloride were heated to reflux3h, recover excess thionyl chloride, distill under reduced pressure, yield153-154℃（ 1.6kpa) fraction to 90-98%the yield of m-nitrobenzoyl chloride is obtained.
