Procedure

Example 1 was repeated at 140° C. with 14.1 g of a granular (4 to 5 mm diameter) titanium dioxide, Calsicat 20503, from the Calsicat company. After 2 h reaction time, the phenol conversion was 7.2%, whereby 0.8 g phenyl chloroformate and 11.0 g diphenyl carbonate were formed. The selectivity to carbonate esters was >99%.
