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 .

In organic chemistry, the desulfonation reaction is the hydrolysis of sulfonic acids: [1] RC 6 H 4 SO 3 H + H 2 O → RC 6 H 5 + H 2 SO 4. The reaction applied to aryl and naphthylsulfonic acids. It is the reverse of sulfonation. [2] The temperature of desulfonation correlates with the ease of the sulfonation.
In the most common route benzene is alkylated by long chain monoalkenes (e.g. dodecene) using hydrogen fluoride as a catalyst. [9] The purified dodecylbenzenes (and related derivatives) are then sulfonated with sulfur trioxide to give the sulfonic acid. [10] The sulfonic acid is subsequently neutralized with sodium hydroxide. [1]
The compound is prepared by the chlorsulfonation of benzene: C 6 H 6 + 2SHO 3 SCl → C 6 H 5 SO 2 Cl + HCl + SO 3. Benzenesulfonic acid is an intermediate in this conversion. Diphenylsulfone is a side product. Benzenesulfonyl chloride can also be prepared by treating benzenesulfonate salts with phosphorus oxychloride. [2]
Trinitrobenzenesulfonic acid (C 6 H 3 N 3 O 9 S) is a nitroaryl oxidizing acid. Due to its extreme oxidative properties, if mixed with reducing agents including hydrides , sulfides , and nitrides , it may begin a vigorous reaction that culminates in almost immediate detonation.
By measuring the pK a at various ionic strengths and extrapolating to zero ionic strength, the pK a of phenylsulfinic acid was determined to be 2.76. [1] This makes phenylsulfinic acid a stronger acid than its corresponding carboxylic acid, benzoic acid (pK a = 4.2), but weaker than its corresponding sulfonic acid, benzenesulfonic acid (pK a ...
Assisted by Lewis acid catalyst, Friedel-Crafts methylsulfonation of aryl ring can be achieved by Ms 2 O. In contrast to MsCl, either activated or deactivated benzene derivatives can form the corresponding sulfonatesin satisfactory yields with Ms 2 O. [ 8 ]
