Linear alkylbenzenes (sometimes also known as LABs) are a family of organic compounds with the formula C 6 H 5 C n H 2n+1. Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C 12 -C 15 , C 12 -C 13 and C 10 -C 13 , for detergent use. [ 1 ]
An alkylbenzene is a chemical compound that contains a monocyclic aromatic ring attaching to one or more saturated hydrocarbon chains. [1] Alkylbenzenes are derivatives of benzene , in which one or more hydrogen atoms are replaced by alkyl groups .
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]
The resulting linear alkylbenzene compounds are sulfonated to give the corresponding sulfonic acids. This sulfonation can be highly specific to place the sulfonic acid group across the ring, in the 4-position.

Linear alkylbenzene sulfonate (LAS) with the formula of C 12 H 25 C 6 H 4 SO 3 Na, also known as sodium dodecylbenzene sulfonate, is the most widely used anionic surfactant in laundry detergent because it has minimal environmental impact for its readily biodegradation.
Detergents. A detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. [1] There are a large variety of detergents. A common family is the alkylbenzene sulfonates, which are soap-like compounds that are more soluble than soap in hard water, because the polar sulfonate is less likely than the polar carboxylate of soap to bind to calcium and other ...
