PHENOLDISULFONIC ACID Chemical Properties,Usage,Production

Uses

In the manufacture of aminophenoldisulfonic acids which are intermediates in the dye industry.

Production Methods

Phenoldisulfonic acid is obtained by hydrolysis of the dichloride with ethyl alcohol and/or water. Nitration and reduction of this acid gives 5- amino-4-hydroxy-1,3-benzenedisulfonic acid. 4-Hydroxy-1,3-benzenedisulfonic acid accelerates the rearrangement of cumene hydroperoxide in the Hock – Lang phenol process.

Purification Methods

Crystallise the acid from EtOH/diethyl ether. [Beilstein 11 H 250, 11 I 58, 11 II 139, 6 III 522.]
