| titleOfInvention | Process for producing aromatic carbonates |
| abstract | The present invention relates to a process for the preparation of an aromatic monohydroxy compound, an alkylaryl carbonate and mixtures thereof, in the presence of a metal-containing catalyst, with a starting material selected from the group consisting of dialkyl carbonates, alkylaryl carbonates and mixtures thereof Wherein the transesterification reaction is selected from the group consisting of an aromatic polyhydroxy compound and a residue thereof on the metal of the metal-containing catalyst, wherein the aromatic polycarbonate is selected from the group consisting of aromatic polyhydroxy compounds and residues thereof Wherein the weight ratio (WR) is measured for the catalyst-containing liquid mixture in the system of the transesterification reaction, wherein the weight ratio (WR) of the aromatic group-containing material Quot; means that the starting material, the reactants of the transesterification reaction and / The. According to the process of the present invention, the transesterification reaction can be carried out without adverse phenomena such as precipitation of the catalyst from the catalyst-containing liquid mixture and deposition of the catalyst precipitated on the inner wall of the reactor, pipe, etc., and the desired aromatic carbonate And can be manufactured stably for a long period of time. |
