PHENOLDISULFONIC ACID Chemical Properties,Uses,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.]
