Abstract:

3,4,5,6-Tetrabromophenolsulfonephthalein was synthesized by the reaction of 2-sulfobenzoic acid cyclic anhydride suffered from bromination with phenol. The crude product was purified by solvent extraction and recrystallization with a purity of the product of 97.45% and a yield of 36.5%, respectively.

Key words: 2-sulfobenzoic acid cyclic anhydride, 3,4,5,6-tetrabromophenolsulfonephthalein, purification
