Benzenesulfonic acid reaction. The reaction rate constant for the reaction of hydroxyl radicals with benzenesulfonic acid was experimentally determined to be 176X10-9 Lmole-sec2. Photolysis of benzenesulfonic acid in an aqueous solution gave sulfurous acid SO2 andor sulfuric acid in a total yield of 3863. A sulfonic acid or sulphonic acid refers to a member of the class of organosulfur compounds with the general formula RSO 2 OH where R is an organic alkyl or aryl group and the SO 2 OH group a sulfonyl hydroxide.
As a substituent it is known as a sulfo groupA sulfonic acid can be thought of as sulfuric acid with one hydroxyl group replaced by an organic substituent. Benzenesulfonic acid p-Toluenesulfonic acid. Except where otherwise noted data are given for materials in their standard state at 25 C 77 F 100 kPa.
What is Infobox references. Sulfanilic acid 4-aminobenzenesulfonic acid is an organic compound with the formula H 3 NC 6 H 4 SO 3. It is an off-white solid.
It is a zwitterion which explains its high melting point. It is a common. The Lewis acid FeBr 3 as a catalysta reaction occurs in which one bromine is substituted for a ring hydrogen.
Because iron reacts with Br 2 to give FeBr 3 iron filings can be used in place of FeBr 3 An analogous chlorination reaction using Cl 2 and FeCl 3 gives chlorobenzene. This reaction of benzene with halogens differs from the reaction of alkenes with halogens in two important ways. The most characteristic reaction of aromatic compounds is substitution at a ring carbon.

The conditions commonly used for the aromatic substitution reactions discussed here are repeated in the table on the right. The electrophilic reactivity of. Sulfonation of benzene is a process of heating benzene with fuming sulphuric acid H2SO4 SO3 to produce benzenesulfonic acid.
The reaction is reversible in nature. The mechanism for Sulfonation of benzene. Due to higher electronegativity oxygen present in sulphuric acid pulls an electron towards itself generating an electrophile.
This attacks the benzene ring leading to the formation of. 16 benzenesulfonic acid sodium salt isomers 17 Dodecylbenzenesulfonate sodium salt isomers 18 Sodium dodecylbenzene sulfonate 2-19 dodecylbenzenesulfonic acid sodium. 2-20 dodecylbenzenesulfonate 3-21 dodecylbenzenesulfonic acid sodium.

Cumulatively these species along with peroxynitrous acid ONOOH nitrogen dioxide NO 2 dinitrogen trioxide N 2 O 3 and others are referred to as reactive nitrogen species RNS.
The increased formation of RNS and the generation of additional ROS equivalents are particularly harmful to the cell as the reaction products are in many.
