A process for producing an unsymmetrical chain carbonic acid ester is described, which comprises reacting a first symmetrical chain carbonic acid ester with a second symmetrical chain carbonic acid ester or a monohydric alcohol in the presence of a catalyst comprising as an active catalyst component an oxide of at least one element selected from the Group IIIB elements of the periodic table.

Process for producing unsymmetrical chain carbonic acid ester

A method of continuously distilling off the components of a mixture containing phenols, water and methanol using a single distillation column, wherein methanol is recovered from the top of the column, water containing phenols is dragged as a side stream from a recovery section of the column, and phenols are recovered as a bottom product. The method permits efficient separation by the single distillation column of the three components with high purity and low utility energy.
