Abstract
1,2-Bis(3,4-dimethylphenyl)ethane was synthesized from alkylation of o-xylene and 1,2-dichloroethane in ionic liquids at room temperature.The ionic liquids were formed from anhydrous AlCl_3 with low-carbon-chain quaternary ammonium salt such as ethylpyridine chloride or n-butylpyridine chloride.The results indicated that reaction mixture was easily separated,and inorganic phase containing ionic liquid could be recycled under optimized reaction conditions:temperature 70℃;n(o-xylene)/(1,2-dichloroethane)=9∶1,reaction time:7h,production yield was 56.7%.
