General description. Benzenesulfinic acid sodium salt when treated with alkynylselenonium salts yields ( Z )-β-alkoxyvinylsulfones . It undergoes rhodium-catalyzed desulfinative coupling with aldehydes to yield ketones  .
Commercially, benzenesulfonic acid sodium salt is more common due to high deliquescence of the base material. 3-Nitrobenzenesulfonic Acid Sodium Salt is used as an intermediate for dyes and fluorescent brightening agent. It is used as an developing agent for electroplating and auxiliary for dying fabrics.

Benzenesulfonic acid (conjugate base benzenesulfonate) is an organosulfur compound with the formula C 6 H 6 O 3 S. It is the simplest aromatic sulfonic acid . It forms white deliquescent sheet crystals or a white waxy solid that is soluble in water and ethanol, slightly soluble in benzene and insoluble in nonpolar solvents like diethyl ether .
Sep 08, 2015· The filtrate is concentrated by evaporation and the solution, which contains the calcium salt of benzene sulfonic acid, is treated with just sufficient sodium carbonate solution to precipitate the calcium as carbonate and convert the sulfonic acid into the sodium salt. The liquid is again, filtered and concentrated, by evaporation, until a sample crystallizes on cooling.
