APPLICATIONS

Sulfonic acid is a compound with general formula RSO2OH, where R is an aliphatic or aromatic hydrocarbon. It is a derivative of sulfuric acid (HOSO2OH) where an OH has been replaced by a carbon group or a compound where a hydrogen atom has been replaced by treatment with sulfuric acid; for example, benzene is converted to benzenesulfonic acid (water-soluble). Sulfonic acid has a sulfur atom bonded to a carbon atom of a hydrocarbon and bonded also to three oxygen atoms, one of which has been attached to a hydrogen atom.

Sulfonic acid is acidic due to the hydrogen atom, stronger than a carboxylic acid. Sulfonic acid is one of the most important organo sulfur compounds in organic synthesis. Sulfonic acids are used as catalysts in esterification, alkylation and condensation reactions. Sulfonates are salts or esters of sulfonic acid. Sulfonic salts are soluble in water. Sulfonic acid and its salts present in organic dyes provide useful function of water solubility and or improve the washfastness of dyes due to their capabiltity of binding more tightly to the fabric.

They are widely used in the detergent industry. Alkylbenzene sulfonic acid is the largest-volume synthetic surfactant because of its relatively low cost, good performance, the fact that it can be dried to a stable powder and the biodegradable environmental friendliness. Sulfonate cleaners do not form an insoluble precipitates in hard water. Sulfonic acid salts and esters are intermediates widely used in organic synthesis and particularly phenolic compounds and cation exchange resins. They are synthetic intermediates for a number of biologically active compounds and pharmaceutical candidates such as sulfa drugs.

Benzenesulfonic acid consumption is linked mostly to phenol and resorcinol production with sodium hydroxide. It is used as a catalyst for dehydration and used in solidifying resins. It is a base material for electroplating solutions. Benzenesulfonic acid, or a derivative thereof, is used as a synthetic intermediate for a number of chemical families of pharmaceuticals, pesticides, dyes, pigments, fluorescent brighteners, and other organic compounds. 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.

OTHER INFORMATION
The prefix nitro- indicates the presence of NO2- radical, while nitrate refers to any salt or ester of nitric acid or the NO3- anion. Nitroso- is the prefix indicating presence of the group -NO and azo- is for -N=N- group. Some range of  organic compounds containing nitrogen include nitro compounds (RNO2 ), nitroso compounds (RNO), amines (R3N ), amino acids, and natural alkaloids or nucleotides. The nitrogen ion in nitro compounds is trigonally planar with 120° angles. There are two resonance bonds so that the two oxygens are equivalent. Nitro compounds are strongly basic due to electron withdrawing both inductively and mesomerically. Historically, they are abundant in dyes and explosives. Nitro compounds, organic hydrocarbons having one or more NO2 groups bonded via nitrogen to the carbon framework, are versatile intermediate in organic synthesis.
