Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethanol | HCID 702 | — |
| Reactant | 4-Nitrobenzoic Acid | HCID 6108 | — |
| Catalyst | HCID 21655683 | HCID 21655683 | — |

| Product | Ethyl 4-nitrobenzoate | HCID 7457 | 94.4% |
Reaction Steps
700 g of toluene, 235 g of ethanol (5.2 mol), 350 g of 4-nitrobenzoic acid and 10 g of hexafluoropropanesulfonic acid hydrate are weighed into a 2-1 four-necked flask equipped as described in Example 1. The procedure described in Example 1 is then repeated. Using the work-up described in Example 1 gives 386 g of ethyl 4-nitrobenzoate and, after drying, 382 g of dry ethyl 4-nitrobenzoate, which corresponds to a yield of 94.4% of theory, in a purity of 99.2% by HPLC of solidification point 56° C.
