HCID 7597Diphenyl carbonate

Procedure

Example 1 was repeated at 140° C. using 14.1 g of γ-aluminium oxide spheres SPH-512 from Rhone-Poulenc. After 2 h reaction time the phenol conversion was 15.8%, wherein 0.4 g of phenyl chloroformate and 25.1 g of diphenyl carbonate were formed. The selectivity to give carbonate and phenyl chloroformate was greater than 99%.

Workup
