nature
Colorless odorless liquid, boiling point 260 ~ 320ºC, insoluble in water, soluble in organic solvents.
preparation
In the presence of aluminum trichloride catalyst, the alkylation reaction of a monoolefin and benzene is carried out, and the reactants are washed by alkali, water, and then debenzenized and rectified to obtain fine alkyl benzene.
Cl0 ~ C13 normal alkane is chlorinated to chloro-alkane, and then aluminum trichloride is used as catalyst to condense with benzene to obtain straight chain alkyl benzene.
use
It is mainly used as an intermediate of laundry detergent, such as sodium dodecyl benzene sulfonate, and is also used to make pesticide emulsifier calcium dodecyl benzene sulfonate.
security
General aromatic hydrocarbons are more toxic, among which benzene has the strongest effect on the central nervous system and blood. When there is an alkyl side chain, the irritation and anesthesia of the mucosa are enhanced, but in vivo, because the side chain is first oxidized into alcohol and then into carboxylic acid, there is no damage to the hematopoietic function. During the production process, attention should be paid to protection, and the operator should wear protective equipment.
Packed in tankers or iron drums, stored and transported according to regulations on toxic combustible products.
