-
Paragraph 0041-0045; 0056; 0061, (2020/02/27)
The invention discloses a method for preparing 3-nitro-4-fluorophenylacetate by using a microreactor, and belongs to the technical field of organic matter synthesis, the microreactor comprises precooling modules and a mixing module, and the method specifically comprises the following steps: (1) preparing raw materials: preparing a mixed solution of 4-fluorophenylacetate and concentrated sulfuric acid and a nitric acid solution; (2) pre-cooling: cooling the pre-cooling modules and the mixing module to a reaction temperature in advance, and then respectively adding the mixed solution of 4-fluorophenylacetate and concentrated sulfuric acid and the nitric acid solution into different pre-cooling modules; (3) mixing: after the raw materials are pre-cooled, adding the pre-cooled raw materials into the mixing module for mixing reaction; and (4) performing quenching and post-processing. The method provided by the invention can effectively control the heat release problem of the nitration reaction, and is high in safety; and the 3-nitro-4-fluorophenylacetate can be prepared with high selectivity, the conversion rate of the 4-fluorophenylacetate can reach 98.4%, and the selectivity can reach99: 1.
