本发明公开了一种隔板蒸馏分离提纯二元酸二甲酯的方法,所述蒸馏分离在相互串联的三个蒸馏塔内依次完成,第二蒸馏塔的底部垂直设有隔板,将其下部空腔分割成第一塔室和第二塔室,第二蒸馏塔的物料进口位于隔板顶部下方,包括以下步骤:将原料混二酸二甲酯进入第一蒸馏塔,轻组分自第一蒸馏塔塔顶分离出来,塔底物料进入第二蒸馏塔,
The invention discloses a method for separating and purifying dimethyl dicarbonate by a separator, the distillation separation is completed in three distillation columns in series with each other, a separator is vertically arranged at the bottom of the second distillation column, The lower cavity is divided into a first column chamber and a second column chamber, and the material inlet of the second distillation column is located below the top of the partition plate. The method comprises the following steps of: feeding the raw material dimethyl carbonate into a first distillation column, The top of the first distillation column is separated, the bottom material enters the second distillation column,
