Product Name:4-Hydroxybenzenesulfonic acid
CAS Number:98-67-9
Molecular formula:C6H6O4S
Molecular Weight:174.17

The synthesis of 4-Hydroxybenzenesulfonic acid is as follows：Phenol (25 kg) and 96% sulfuricacid(28 kg) are heated to 50 ℃; then1.25 kg additional sulfuric acid is added and the reaction mixture is heated at 110 ℃ for 5 – 6 h. Reaction water, together with about 5% of the phenol, is distilled off during this period. Yield 95%.
