A method for synthesizing di-tert-butyl dicarbonate by adopting a phase transfer catalysis method belongs to the technical field of organic synthesis technology. Using triphosgene and tert-butanol as raw materials to synthesize di-tert-butyl dicarbonate under the conditions of adding alkali and phase transfer catalyst, avoiding the use of dangerous phosgene as raw materials, the reaction conditions are mild, and the reaction time is greatly shortened. Larger application value.
