| description | The invention relates to the technical field of chemical products, and discloses a method for synthesizing di-tert-butyl dicarbonate ester by adopting a phase transfer catalysis method, which comprises the following steps: S1, reacting sodium tert-butoxide with carbon dioxide to generate mono-tert-butyl sodium carbonate; s2, reacting the generated mono-tert-butyl sodium carbonate with phosgene, solid phosgene and aliphatic/aromatic sulfonyl chloride to generate di-tert-butyl tricarbonate; s3, the generated di-tert-butyl tricarbonate reacts with a catalyst triethylamine or N, N-tetramethylethylenediamine, one molecule of carbon dioxide is released, and the tert-butyl dicarbonate is generated. Compared with a traditional technology, the method for synthesizing the di-tert-butyl dicarbonate is stable, and the yield of the generated tert-butyl dicarbonate is high.
