(1,2-DICHLOROETHYL)BENZENE(CAS: 1074-11-9)

(1,2-Dichloroethyl)benzene has a crystalline form with a molecular weight of approximately 180.02 g/mol. It is slightly soluble in water but more soluble in organic solvents like ethanol and acetone. The compound shows low reactivity, but it can undergo substitution reactions and polymerization under certain conditions. It has a melting point of 43-44°C and a boiling point of 150-152°C.

(1,2-Dichloroethyl)benzene is typically synthesized by the chlorination of ethylbenzene using chlorine gas in the presence of a Lewis acid catalyst, such as ferric chloride. The reaction is carried out at elevated temperatures and proceeds with good selectivity to form the desired dichloro compound, yielding up to 90% product. The process requires proper handling of chlorine and the catalyst.

(1,2-Dichloroethyl)benzene finds applications in the pharmaceutical industry for the synthesis of certain intermediates, and in the polymer industry as a monomer or additive. It is also used in the production of sensors and as a raw material in the manufacture of semiconductors for electronic devices.

When handling (1,2-Dichloroethyl)benzene, it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and chemical-resistant clothing. Work should be carried out in a well-ventilated area or a fume hood. In case of skin contact, immediately wash the affected area with soap and water. Ingestion is highly unlikely as the compound is not used in food applications. Refer to the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
