Dodecylbenzene is an organic compound with the formula C12H25C6H5.Dodecylbenzene is a colorless liquid with a weak oily odor. Floats on water.
This colourless waxy solid consists of a dodecyl group (C12H25) attached to a phenyl group (C6H5). Dodecylbenzene is a precursor to sodium dodecylbenzenesulfonate, a surfactant that is a key ingredient of household laundry detergents, such as detergent powder.
This compound and some related alkylbenzene are produced industrially by alkylation of benzene with the corresponding alkenes in the presence of hydrogen fluoride or related acid catalysts. 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. The resulting sulfonic acid is then neutralized with base to give sodium alkylbenzenesulfonate, which is subsequently blended with other components to give various cleaning products.
