Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Sulfuric Acid | HCID 1118 | — |
| Reactant | 4-Aminobenzaldehyde | HCID 11158 | — |
| Solvent | Dimethylformamide | HCID 6228 | — |
| Product | 4-Hydroxybenzaldehyde | HCID 126 | 23% |
Reaction Steps
The procedure of Example 1 was repeated except that the N,N-dimethylformamide was not added and p-aminobenzaldehyde was reacted with sulphuric acid in 40% aqueous solution at 40° C. for one hour, to obtain p-hydroxybenzaldehyde in a yield of 23%, based on the weight of p-nitrotoluene used.
