ДОДЕЦИЛБЕНЗОЛ

Химические свойства

Colorless, odorless liquid. Insoluble in water, soluble in organic solvents.

Использование

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.

Подготовка

n-Dodecylbenzene was prepared by lauroyl chloridation, Friedel-Crafts acylation and Huang Minglong deoxidization, followed by purification with vacuum distillation and recrystallization procedures.

прикладной

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.

Общее описание

Dodecylbenzene is a colorless liquid with a weak oily odor. Floats on water. (USCG, 1999)

Реакции воздуха и воды

Insoluble in water.

Профиль реактивности

Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as DODECYLBENZENE, 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.

Угроза здоровью

Liquid causes mild irritation of eyes and may cause allergenic responses on repeated contact with skin. Ingestion causes nausea.

Пожароопасность

DODECYLBENZENE is combustible.
