Process for the continuous preparation of aryle carbonates |
| abstract |
Organic carbonates containing at least one aromatic ester group can be obtained in a continuous manner from carbonates containing at least one aliphatic ester group and a phenolic compound in the presence of a transesterification catalyst known per se by carrying out the reaction in a bubble column reactor or in a cascade at least two bubble columns is carried out in such a way that the phenolic compound is metered into the first bubble column and the carbonate containing at least one aliphatic ester group into each individual, but preferably only into the last bubble column. The carbonate containing at least one aromatic ester group is withdrawn in liquid form from the last bubble column. Volatile reaction products, e.g. alcohol or a dialkyl carbonate which has been split off are removed at the upper end of each individual column, preferably at the upper end of the first bubble column. <IMAGE> |
