摘要： A process is described for working up liquid reaction mixtures such as are formed during dimethyl carbonate preparation by oxidative carbonylation of methanol in the presence of a copper-containing catalyst, which process permits a simple separation of the water of reaction from the dimethyl carbonate. In this process, in a first distillation column, the water of reaction is taken from the bottom of the column; the top product from the first column is separated in a second column, under increased pressure, into dimethyl carbonate as bottom product and into a top product which is predominantly composed of methanol. The top product from the distillative working-up in the second column, which is predominantly composed of methanol, is recycled to the reaction process.

摘要： Organic carbonates which contain at least one aromatic ester group can be obtained continuously from carbonates, which contain at least one aliphatic ester group, and a phenolic compound in the presence of a transesterification catalyst known per se in that the reaction is carried out in a bubble column reactor or in a cascade of at least two bubble column reactors 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 is metered into each individual bubble column, but preferably only into the last bubble column. The carbonate containing at least one aromatic ester group is taken off in the liquid state from the last bubble column. Volatile reaction products, for example eliminated alcohol or a dialkyl carbonate are taken off at the upper end of each individual bubble column, preferably at the upper end of the first bubble column.

摘要： The invention relates to a process for preparing a diaryl carbonate by oxidative carbonylation of the basic aromatic hydroxy compound, in which the aromatic hydroxy compound is the one which is eliminated during melt polycondensation of this diaryl carbonate with a bisphenol. Accordingly the invention also relates to the preparation of polycarbonates by melt polycondensation of diaryl carbonates with bisphenols in which the aromatic hydroxy compounds which is eliminated is used again to prepare the diaryl carbonate. In the event that the aromatic hydroxy compound eliminated is also the basic unit in the bisphenol used, proportions of it may be used to prepare both the diaryl carbonate and the bisphenol.
