| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Dimethyl Carbonate | HCID 12021 | — |
| Reactant | Phenyl acetate | HCID 31229 | — |
| Catalyst | Titanium tetra(methanolate) | HCID 164767 | — |
| Product | Diphenyl carbonate | HCID 7597 | — |

Reaction Steps
In the aforesaid apparatus, at 145° C., were charged 74 g of phenyl acetate and, gradually, 90 g of dimethyl carbonate and 1 g of titanium tetramethoxide. Methyl acetate being continuously distilled, after 4 hours there were obtained 80% by mole of diphenyl carbonate and 18% by mole of phenyl methyl carbonate, at selectivity higher than 98% and 97% conversion of methyl acetate.
