Zusammenfassung: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. 本发明涉及化学制品工艺领域,且公开了一种采用相转移催化法合成二碳酸二叔丁酯的方法,包括以下步骤:S1:由叔丁醇钠与二氧化碳反应生成单叔丁基碳酸钠;S2:将生成的单叔丁基碳酸钠与光气、固光、脂肪族/芳香族磺酰氯反应生成三碳酸二叔丁酯;S3:将生成的三碳酸二叔丁酯与催化剂三乙胺或N,N-四甲基乙二胺反应,
