Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Phosgene | HCID 6371 | — |
| Reactant | P-Toluic Acid | HCID 7470 | — |
| Solvent | Chlorobenzene | HCID 7964 | — |

Reaction Steps
81.4 g (0.6 mol) of p-toluic acid and 892 g of monochlorobenzene are introduced into the reactor and 582 g (5.9 mol) of phosgene are then added. The set pressure is adjusted to 11.2 bar relative and the reaction medium is heated. The reaction is complete after 3 hours. Analysis of the final reaction medium is carried out by gas chromatography. The level of residual acid is 0.3 mol % and the level of toluoyl chloride obtained is 99.7 mol %.
