Hazard InformationBack Directory
[General Description]

Sodium dodecylbenzenesulfonate is a white to light yellow flakes, granules or powder. SODIUM DODECYLBENZENESULFONATE (BRANCHED CHAIN)(25155-30-0) is soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. SODIUM DODECYLBENZENESULFONATE (BRANCHED CHAIN)(25155-30-0) is used as a synthetic detergent.
[Reactivity Profile]

SODIUM DODECYLBENZENESULFONATE is incompatible with strong oxidizers.
[Air & Water Reactions]

SODIUM DODECYLBENZENESULFONATE (BRANCHED CHAIN) is soluble in water.
[Health Hazard]

Minor skin and eye irritant. INGESTION: May cause vomiting, diarrhea, and intestinal distension.
[Description]

Sodium dodecyl benzene sulfonate is a series of organic compounds with the formula C12H25C6H4SO3Na. It is a colourless salt with useful properties as a surfactant. It is usually produced as a mixture of related sulfonates. It is a major component of laundry detergent.
[Chemical Properties]

white or light yellow flakes
[Uses]

A surfactant used in proteomics research.
[Uses]

Anionic detergent.
[Industrial uses]

These frothers are mixtures of alcohols containing 6–8 carbon atoms. They were at one time marketed by DuPont and they are tailored frothers for specific ore types. The bestknown frother from this group is methyl isobutyl carbinol (MIBC) and 2-ethyl hexanol.
Aliphatic alcohol frothers are used as mixtures of different carbon lengths and as a mixture of hydrocarbon oils.
[Purification Methods]

It crystallises from propan-2-ol or H2O. [Gray et al. J Org Chem 20 515 1955, Beilstein 11 IV 514.]
[Environmental considerations]

Biodegradability has been well studied , and is affected by the isomerization (branching). The salt has an LD50 of 2.3 mg / liter for fish , about 4x more toxic than the branched tetra propylene benzene sulfonate. It is however biodegraded more rapidly. Oxidative degradation initiates at the alkyl chain.
[Alkyl benzene sulfonates]

Most sodium dodecyl benzene sulfonates are a member of the linear alkyl benzene sulfonates, meaning that the dodecyl group (C12H25) is un branched. This dodecyl chain is attached at the 4- position of the benzene sulfonate group. Linear dodecyl-4-benzene sulfonate anions can exist in six isomers (ignoring optical isomers), depending on the carbon of the dodecyl group that is attached to the benzene ring. The isomer shown below left is 4-(5-dodecyl ) benzene sulfonate (4 indicating the position of the benzene ring, 5 indicating the position on the dodecane chain). Branched isomers, e.g. those derived from tetramerized propylene, are also known (below right) but are not as widely used because they biodegrade too slowly.
Production
Trillions of kilograms are produced annually. Given the large scale of the application, the alkyl benzene sulfonates have been prepared by many methods. In the most common route, benzene is alkylated by long chain mono alkenes (e.g. dodecene) using hydrogen fluoride as a catalyst. The purified dodecyl benzenes (and related derivatives) are then sulfonated with sulfur trioxide to give the sulfonic acid. The sulfonic acid is subsequently neutralized with sodium hydroxide.
