Method for controllably synthesizing 2-bromo-1, 2-diphenyl perfluoroheptanoate by composite emulsion cascade microreactor

The invention discloses a method for controllably synthesizing 2-bromine-1, 2-diphenyl perfluoroheptanoate by using a composite emulsion cascade microreactor. According to the method, different reactants, intermediates and catalysts are dissolved in a multi-chamber micro-area high-selectivity mode in composite emulsion liquid drops, existence and generation of reaction substrates, reaction intermediates and products which are sensitive to water are protected, a controllable phase interface sequence and an interface area are utilized, the addition-esterification cascade reaction sequence is achieved, and the yield of the product is improved. Therefore, efficient and controllable cascade reaction is realized in a water dispersion system. In the reaction process, an intermediate does not need to be separated and purified, efficient synthesis of the 2-bromo-1, 2-diphenyl perfluoroheptanoate is achieved under the conditions of no stirring and room temperature, and 100% conversion of an addition reaction and 87% co
