| Hazard Information | Back Directory | [Chemical Properties]
Colorless, odorless liquid. Insoluble in water, soluble in organic solvents. | [Uses]
n-Dodecylbenzene, is a precursor to sodium dodecylbenzenesulfonate, a surfactant that is a key ingredient of household laundry detergents, such as Tide. It is a widely used cleaner, dyeing assistant in textile industrial, degrease agent in electroplate, leather, de- inking agent in papering, rubber and plastic, break emulsion agent in oil industry, artesian well foaming agent in oil well. | [Application]
Dodecylbenzene is used as a raw material for synthetic laundry detergents and production of biodegradable detergents.
1-Phenyldodecane acts as a pseudo-stationary phase (PSP) marker in the preparation of microemulsion. | [Preparation]
n-Dodecylbenzene was prepared by lauroyl chloridation, Friedel-Crafts acylation and Huang Minglong deoxidization, followed by purification with vacuum distillation and recrystallization procedures. | [General Description]
Dodecylbenzene is a colorless liquid with a weak oily odor. Floats on water. (USCG, 1999) | [Air & Water Reactions]
Insoluble in water. | [Reactivity Profile]
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as Dodecylbenzene(123-01-3), and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction. | [Health Hazard]
Liquid causes mild irritation of eyes and may cause allergenic responses on repeated contact with skin. Ingestion causes nausea. | [Fire Hazard]
DODECYLBENZENE is combustible. | [Biochem/physiol Actions]
1-Phenyldodecane was degraded to phenylacetic acid by an oil-degrading bacterium. |
