Phenyldodecan - Preparation Method
Open Data Verified Data
- Direct synthesis of a-olefin and benzene in the presence of aluminum trichloride catalyst, alkylation reaction, reactants by alkali washing, water washing, and then by benzene removal, rectification, that is, refined alkylbenzene.
- chloride method Cl0 ~ C13 n-alkanes are chlorinated to form chlorinated alkanes, and then condensed with benzene to obtain linear alkylbenzene using aluminum trichloride as a catalyst.

Phenyldodecan - Application
Open Data Verified Data
It is mainly used as an intermediate of washing powder, such as sodium dodecylbenzene sulfonate, and also used in the preparation of pesticide emulsifier calcium dodecylbenzene sulfonate.

Phenyldodecan - Safety
Open Data Verified Data
- aromatic hydrocarbons are generally toxic, and benzene has the strongest effect on central nervous system and blood. When with alkyl side chain, the stimulation of the mucosa and narcotic enhancement, but in vivo, because the side chain is first oxidized into alcohol and then into carboxylic acid, so the hematopoietic function is not damaged. During the production process, attention should be paid to protection, and the operator should wear protective equipment.
- the container shall be packed with a tank car or iron drum, and be stored and transported according to the regulations for toxic and combustible products.
