| Abstract: | A new technology for the preparation of p-nitrobenzylcyanide was studied by nitration of benzylcyanide using the mixture of H2SO4,H3PO4 and HNO3 as the orientation nitrating agent.The influences on the product yield of reaction temperature,reaction time and quantity of H2SO4,H3PO4 and HNO3 were investigated.Under the optimum conditions,parallel experimental results showed that the yield of p-nitrobenzylcyanide could reach 70.50%.IR,UV, 1HNMR and elementary analysis proved the structure of product. |
