Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Phenol | HCID 996 | — |
| Reactant | Phosgene | HCID 6371 | — |
| Reactant | Triphenylphosphine | HCID 11776 | — |
| Product | Phenyl chloroformate | HCID 15891 | 90.6% |
Reaction Steps
The distillation residue is re-used with 500 g of phenol and 540 g of phosgene, without the use of fresh triphenylphosphine. After a phosgenation time of 10 hours, 754 g of distilled chloroformic acid phenyl ester are obtained (purity 99.8%; yield 90.4% of the theoretical yield).
