Procedure

In a 3-necked flask fitted with a thermometer and reflux condenser, a mixture of 9.4 g (0.1 mol) of phenol and 15.7 g (0.1 mol) of phenyl chloroformate was heated in the presence of 0.94 g (10 wt. % w.r.t. phenol) of powdered H-ZSM 5. After 2 h at 160° C. a phenol conversion of 72% to give diphenyl carbonate was found. The selectivity was>99%.
