Abstract
4-Bromomethyl-benzonitrile was prepared with p-methyl-benzonitrile and bromine by photochemical bromination.The crude product was washed and recrystallized by solvent and mixed solvent.The reaction conditions were explored and the optimal conditions were as follows.n(4-methyl-benzonitrile) ∶n(bromine)=1 ∶1.1,reaction temperature was 145~150 ℃.Ethanol and mixed solvent consisting of ethanol and ethyl acetate were selected as washing and recrystallizing solvent respectively.IR and MS were employed for qualitative analysis.The product was analyzed by GC and the purity was above 99%.The total yield was 68.6%.
