Dodecylbenzenesulphonic acid Usage And Synthesis
Chemical Propertiesbrown or tan solid
UsesDopant for conducting polymers strong acid catalyst for amino cross-linked coatings
DefinitionChEBI: 2-dodecylbenzenesulfonic acid is a member of the class dodecylbenzenesulfonic acids that is benzenesulfonic acid in which the hydrogen at position 2 of the phenyl ring is substituted by a dodecyl group. It has a role as an animal metabolite.
General DescriptionDodecylbenzenesulphonic acid is a colorless liquid. Dodecylbenzenesulphonic acid is soluble in water. Dodecylbenzenesulphonic acid is corrosive to metals and tissue. Dodecylbenzenesulphonic acid is used to make detergents.
Air & Water ReactionsSoluble in water.
Reactivity ProfileDodecylbenzenesulphonic acid is corrosive. When heated to decomposition or on contact with strong acids produces highly toxic fumes of oxides of sulfur. The toxicity and hazards of individual alkylbenzene sulfonic acids must be assessed individually [Kirk-Othmer, 3rd ed., Vol. 22, 1978, p. 45].
Health HazardEYES AND SKIN: A 0.5% to 1% concentration in water caused significant irritation. The technical grade is corrosive and may cause irreversible damage to eyes and skin. INGESTION: Irritation of the mouth, esophagus and stomach. Diarrhea, intestinal distention and occasional vomiting.
Fire HazardSpecial Hazards of Combustion Products: May give off SO 3 , SO 2 and H 2 S
Flammability and ExplosibilityNotclassified
Agricultural UsesInsecticide, Adjuvant, Biocide: Dodecylbenzenesulfonic acid and its salts are used as degreasers in meat-cutting rooms. Also used as a laboratory chemical, to make detergents, and in electronically cleaning and pickling baths. Not listed for use in EU countries. Approved for use in the U.S. and other countries. There are 30 global suppliers.
