| Abstract: | 4-nitrophenyl ethyl bromide was synthesized from β-bromophenyl ethane with acetic acid, acetic anhydride and fuming nitric acid as nitrating agent. The influence of reaction factors on the yield of product 4-nitrophenylethyl bromide was studied. It is showed that the yield of product ean be 69.2% with the reaction temperature -5℃; 0.15mol fuming nitric acid and 0.12mol acetic anhydride being need for 0.1mol β-bromophenyl ethane and the reaction time 4 hour. |
