摘　　要：正戊醛是合成香料双氢茉莉酮酸甲酯的重要原料。目前为止,大多数厂家均采用钴、铑催化剂进行羰基合成,但由于我国铑资源短缺,而钴催化法则不大适合用来合成醛。文中介绍了以2-丁烯为原料,用铁钴簇催化剂羰基合成法制正戊醛的新方法,与用贵金属铑、钴催化剂法相比,可降低产品成本。N-amyl aldehyde is a main raw material in the synthesis of methyl dihydrojasmonate fragrance. By now most of the producers have adopted oxo reaction based on Co or Rh as catalysts. But Rh resource is in short supply in China and the technology using Co catalysis is not suitable for synthesis of aldehydes . This article introduces the new method of producing n - amyl aldehyde with 2-butene as raw material and Fe-Co as catalyst via oxo reaction. It can decrease the cost comparing with the method of using noble metals Co or Rh as catalyst.
