What is benzenesulfonic acid?

Benzenesulfonic acid is a colorless needle shaped or leaf shaped crystal that is highly soluble in water and ethanol, insoluble in ether and carbon disulfide, and slightly soluble in benzene. It is strongly acidic, comparable to sulfuric acid, but non oxidizing. The dissociation Chemicalbook constant K=0.2 (25 ℃). The sulfonic acid group of benzenesulfonic acid can be replaced by various functional groups and fused with sodium hydroxide to form sodium phenolate; React with sodium cyanide to produce benzonitrile; React with bromine to produce bromobenzene;

Application

Benzenesulfonic acid is commonly used as a catalyst and water absorbent in esterification and dehydration reactions. Its advantage is that it has weaker oxidizing properties than sulfuric acid and can reduce side reactions. Benzenesulfonic acid is mainly used for alkali melting to produce phenol, as well as for the production of resorcinol, and is commonly used as a catalyst in esterification and dehydration reactions. Benzenesulfonic acid can also be used for oilfield water injection, which can relieve formation blockage and improve formation permeability. Benzenesulfonic acid is also used as a catalyst for esterification and dehydration reactions, and as a curing agent in the casting industry.
