Reaction equation

S([O-])([O-])(=O)=O.N[C:7]1[CH:14]=[CH:13][C:10]([CH:11]=[O:12])=[CH:9][CH:8]=1.S(=O)(=O)(O)[OH:16]>>[OH:16][C:7]1[CH:14]=[CH:13][C:10]([CH:11]=[O:12])=[CH:9][CH:8]=1

Participants

Reactant 3

HCID 1117Sulfate Ion

HCID 1118Sulfuric Acid

HCID 111584-Aminobenzaldehyde

Product 1

HCID 1264-Hydroxybenzaldehyde

Procedure

The procedure of Example 8 was followed except that the production of the sulphate of p-aminobenzaldehyde by reaction with sulphuric acid in 40% aqueous solution was effected at 40° C. for one hour, to obtain 2.0 g (0.016 mol) of p-hydroxybenzaldehyde. The yield thereof was 41%, based on the weight of p-aminobenzaldehyde used.
