Benzene sulfonic acid. 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.
It is often stored in the form of alkali metal salts. Benzenesulfonic acid biodegraded with a lag time of 100-110 hours a rate of 0013-0034 per hour and a half-life of 170-180 hours using a electrolytic respirometer in water indicating that it is biodegraded partially in a long time by acclimatized microorganisms45. Benzenesulfonic acid degraded greater than 90 after 9 days with 2 days of acclimation and a degradation rate after.
Whereas benzene sulfonic acid hydrolyzes above 200 C most related derivatives are easier to hydrolyze. Thus heating aryl sulfonic acids in aqueous acid produces the parent arene. This reaction is employed in several scenarios.
In some cases the sulfonic acid serves as a water-solubilizing protecting group as illustrated by the purification of para-xylene via its sulfonic acid derivative. Alkyl benzene sulfonic acid labsa. US 165 Liter.

Here we present an updated version of a protocol we published in 2007 for key models of acute and chronic forms of colitis induced by 246-trinitro-benzene sulfonic acid TNBS oxazolone and dextran sulfate sodium DSS. This protocol update describes an adaptation of the existing protocol that modifies the technique.
