Paragraph 0026, (2020/12/30)
The invention discloses a production process of ethyl bromodifluoroacetate. The production process comprises the following steps: 1, bromination reaction; 2, elimination reaction; 3, oxidation reaction; 4, esterification reaction. Compared with other methods, the bromination addition reaction only needs to be carried out at normal pressure and under the catalysis of infrared light, so that the cost is saved compared with other catalysts, other impurities are not introduced, and the utilization rate of bromine is increased. The elimination reaction adopts a dropwise adding mode, so the reactionrate can be effectively controlled, and the flooding phenomenon which is easy to generate is avoided. The purity of the prepared finished product is greater than or equal to 99.0%, and the yield is greater than or equal to 80.0%.
