Colorless liquid; [ICSC]

Sources/Uses

Used to make linear alkylbenzenesulfonate surfactants, dodecylnitrobenzene, dodecylaniline, and dodecylbenzyl chloride; as vehicle and solvent for polynuclear aromatics in carcinogenesis studies; as solvent for organophosphorus insecticides; to make arylalkyl sulfonates in soap and detergent industry; [HSDB] Not produced in commercial quantity as pure substance, rather as mixtures of long-chain linear alkylbenzenes with alkyl group containing from 10 to 16 carbon atoms; The detergent surfactant LAS uses more than 98% of all linear alkylbenzenes; [eChemPortal: SIDSUNEP]
