Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethanol | HCID 702 | — |
| Reactant | Sulfuric Acid | HCID 1118 | — |
| Reactant | 4'-Hydroxy-4-biphenylcarboxylic acid | HCID 301556 | — |
| Product | Ethyl 4'-hydroxy-4-biphenylcarboxylate | HCID 4049156 | 97% |
Reaction Steps
1 ml of conc. sulfuric acid was added to an ethanol solution of 0.1 mole (21.4 g) of 4'-hydroxybiphenyl-4-carboxylic acid, and stirred for 18 hours. The reaction solution was concentrated, and then purified by column chromatography, to obtain 22.8 g of 4'-hydroxybiphenyl-4-carboxylic acid ethyl ester [m.p. 144.4°-145.6° C⟧ (yield: 97%)
