Abstract
The invention discloses a synthesis method of 3-trifluoromethyl-1, 4, 2-dioxazole-5-one, and relates to the technical field of battery electrolyte additives. The synthesis method comprises the following steps: taking 2, 2, 2-trifluoro-N-hydroxyacetamide and phosgene, and carrying out a cyclization reaction to obtain the 3-trifluoromethyl-1, 4, 2-dioxazole-5-one. Compared with the prior art, the synthesis method of 3-trifluoromethyl-1, 4, 2-dioxazole-5-one has the advantages that the reaction process is milder and safer, the product yield and the product purity in the production process are ensured to be maximized by controlling the reaction conditions in each stage, the product yield is further improved by reasonably controlling the dosage of the reaction raw materials and the reaction process, the yield reaches 54.38% or above, and the purity reaches 99.5% or above.
