Abstract β-bromoethyl benzene(β-BEB) was synthesized by anti-Markovnikov addition of hydrogen bromide to styrene.The reaction conditions such as the reaction time,the amounts of solvent and radical initiators,and the reaction temperature were studied.Finally,the product was analyzed by gas chromatographic analysis.Under the optimum reaction conditions that HBr was 1.2 mole of styrene,the volume of heptane was 5 times of styrene,the mass percentage of azobisisobutylnitrile(AIBN) was 0.5% of styrene,the reaction temperature was(80 ℃) and the reaction time was 60 min,the yield of β-BEB ≥92.0% and the purity ≥96.8%.
