Phenol → 4-Hydroxybenzenesulfonic acid
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Phenol | HCID 996 | — |
| Reactant | Sulfuric Acid | HCID 1118 | — |
| Product | 4-Hydroxybenzenesulfonic acid | HCID 4765 | 60% |
Reaction Steps
Thus, using 1.8 mole % of sulfuric acid based on the phenol to form the phenolsulfonic acid to be the catalyst, a yield of 60% was obtained after 2 hours of reaction at a mole ratio of 2:1 of acetic acid to the phenol, and a 74% yield was obtained after 4 hours at a mole ratio of 2.5:1.
