摘要： A process for the continuous splitting of polycarbonates into dihydroxy compounds and carbonic acid esters is disclosed. Accordingly there are reacted in a distillation column a polycarbonate resin and a monohydroxy compound in the presence of a transesterification catalyst. The polycarbonate, in molten form or as a solute, is continuously fed into the upper part of the column and the monohydroxy compound in vapor phase is continuously fed into the lower part of the column. The resulting carbonic acid ester and dihydroxy compounds are continuously being removed from the column. The process is eminently suitable for the recycling of polycarbonate waste.

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.
