Dodecylbenzenesulfonic acid
Dodecylbenzenesulfonic acid (DBSA) is an organic compound with the formula CH3(CH2)11C6H4SO3H. It is a colorless salt that is used in the laboratory as a strong acid that is soluble in organic compounds. It is the most widely produced sulfonic acid.
Production[edit | edit source]
Dodecylbenzenesulfonic acid is produced by sulfonation of dodecylbenzene (a alkylbenzene), which is derived from the polymerization of propylene, a byproduct of oil refining. The sulfonation is achieved with sulfuric acid. The resulting sulfonic acid is then neutralized with sodium hydroxide to give the sodium salt.
Uses[edit | edit source]
Dodecylbenzenesulfonic acid is used as a catalyst in the esterification of fatty acids. It is also used as a surfactant in detergents and cleaning products, and as an emulsifier in paints and coatings. In addition, it is used in the production of phenolic resins and polyurethane foams.
Safety[edit | edit source]
Dodecylbenzenesulfonic acid is a strong acid and can cause burns if it comes into contact with the skin or eyes. It is also harmful if swallowed or inhaled. Proper safety measures should be taken when handling this chemical.
