The sulfonate ion. In organosulfur chemistry, a sulfonate is a salt, anion or ester of a sulfonic acid. Its formula is R−S(=O) 2 −O −, containing the functional group −S(=O) 2 −O −, where R is typically an organyl group, amino group or a halogen atom. Sulfonates are the conjugate bases of sulfonic acids.
Sodium dodecyl sulfate (SDS) or sodium lauryl sulfate (SLS), sometimes written sodium laurilsulfate, is an organic compound with the formula CH 3 (CH 2) 11 OSO 3 Na and structure H 3 C−(CH 2) 11 −O−S(=O) 2 −O − Na +. It is an anionic surfactant used in many cleaning and hygiene products. This compound is the sodium salt of the 12 ...
Sodium benzenesulfonate is an organic compound with the formula C 6 H 5 SO 3 Na. It is white, water-soluble solid, It is produced by the neutralization benzenesulfonic acid with sodium hydroxide. It is also a common ingredient in some detergents. The compound typically crystallizes from water as the monohydrate. [1]
Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na 2 SO 4 as well as several related hydrates. All forms are white solids that are highly soluble in water. With an annual production of 6 million tonnes, the decahydrate is a major commodity chemical product.
General structure of a sulfonic acid with the functional group indicated in blue. In organic chemistry, sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O) 2 −OH, where R is an organic alkyl or aryl group and the S(=O) 2 (OH) group a sulfonyl hydroxide.

An example of a linear alkylbenzene sulfonate (LAS) Linear alkylbenzene sulfonates (LAS) are prepared industrially by the sulfonation of linear alkylbenzenes (LABs), which can themselves be prepared in several ways. [2] In the most common route benzene is alkylated by long chain monoalkenes (e.g. dodecene) using hydrogen fluoride as a catalyst. [9]
Sodium polystyrene sulfonate is used as a superplastifier in cement, as a dye improving agent for cotton, and as proton exchange membranes in fuel cell applications. In its acid form, the resin is used as a solid acid catalyst in organic synthesis , [ 16 ] mostly commonly under the tradename Amberlyst.
Sodium lignosulfonate (lignosulfonic acid, sodium salt) is used in the food industry as a de-foaming agent for paper production and in adhesives for items that come in contact with food. It has preservative properties, and is used as an ingredient in animal feeds.
