Dodecylbenzenesulphonic acid Usage And Synthesis

Chemical Properties

brown or tan solid

General Description

Dodecylbenzenesulphonic 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 Reactions

Soluble in water.

Reactivity Profile

Dodecylbenzenesulphonic 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 Hazard

EYES 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 Hazard

Special Hazards of Combustion Products: May give off SO 3 , SO 2 and H 2 S

Agricultural Uses

Insecticide, 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.
