| titleOfInvention | Process for production of aromatic carbonate |
| abstract | The present invention provides a process for the production of an aromatic carbonate, comprising the steps of: continuously feeding an aliphatic carbonate represented by following general formula (1) as a starting material, an aromatic monohydroxy compound represented by following general formula (2) as a reactant, and a metal-containing catalyst into a stage above the bottom of a first multi-stage distillation column so as to bring about reaction; continuously withdrawing from the reaction system in a gaseous form a low boiling point component containing an alcohol by-produced in the reaction; and continuously withdrawing from a lower portion of the column in a liquid form an aromatic carbonate represented by following general formula (3) obtained from the starting material and the reactant (see formula 1) Ar1OH (2) wherein R1 in general formulae (1) and (2) represents an aliphatic group having 4 to 6 carbon atoms, and Ar1 represents an aromatic group having 5 to 30 carbon atoms (see formula 3) wherein R 2 and Ar2 in general formulae (3) are the same as R1 and Ar1 in the starting material and the reactant, respectively. Wherein said metal-containing catalyst is an organic titanate having at least one TiO-Ti linkage therein. |
