[Description]

Benzaldehyde-2,4-disulfonic acid is freely soluble in water. The sodium salt crystallizes with 2 mol of H 2 O and is freely soluble in water and poorly soluble in ethyl alcohol. It is made by reaction of 2,4-dichlorobenzaldehyde with sodium hydrogensulfite liquor or oxidation of 2,4- toluenedisulfonic acid with manganese dioxide in sulfuric acid. The acid is used in the production of triphenylmethane dyes and wetting agents.
[Uses]

Benzaldehyde-2,4-disulfonic acid is used in the production of acid dyes.
