4,5-DICHLOROPHTHALIC ACID Usage And Synthesis

Purification Methods

Crystallise the acid from water. It has been purified by converting to the anhydride, reacting it with boiling EtOH to form the monoethyl ester (m 133-134o) and hydrolysing it back to the diacid (see next entry). [Beilstein 9 III 4205.]
