(57) [Problem] To provide a method for producing high-purity dimethyl carbonate by efficiently removing glycol ether by-produced in a transesterification reaction using ethylene carbonate and methanol as raw materials. A reaction product obtained by subjecting ethylene carbonate to a transesterification reaction of methanol is converted into a theoretical plate having 1 theoretical plate. Distillation is performed using a zero-stage or more distillation column to concentrate the by-product glycol ether in the column, extract it from the side stream, and distill high-purity dimethyl carbonate containing no glycol ether from the top of the column. Characteristic method for producing high-purity dimethyl carbonate. |
