Phenolsulfonic acid has three isomers: o-hydroxybenzenesulfonic acid, p-hydroxybenzenesulfonic acid, and m-hydroxybenzenesulfonic acid. It is easy to absorb moisture and crystallize when placed in the air. Products are generally formulated into aqueous solutions. It has a strong irritating effect on skin and mucous membranes. No fixed melting point. Soluble in water and ethanol. The aqueous solution is strongly acidic. O-hydroxybenzenesulfonic acid is produced by sulfonation of phenol with concentrated sulfuric acid at low temperature; p-hydroxybenzenesulfonic acid is produced by sulfonation of concentrated sulfuric acid at 90-100℃. The ortho, para and meta isomers can transform into each other under certain reaction conditions. Phenolsulfonic acid is the most important additive in the acidic tin plating process. It can also be used for acidic resin foaming, organic synthesis, and is an intermediate for pharmaceuticals and dyes.
