HCID 7597Diphenyl carbonate

Procedure

Example 1 was repeated using 14.1 g of powdered H-ZSM 5 at 160° C. After 2 h reaction time the phenol conversion was 8.3%, wherein 0.5 g of phenyl chloroformate and 12.4 g of diphenyl carbonate were formed. The selectivity to give the carbonate and phenyl chloroformate was ca. 96%.
