摘　　要：用ＸＲＤ和ＩＲ对合成混合醇催化剂进行了物相分析．结果表明，催化剂中铜和钴分别以ＣｕＯ，Ｃｏ３Ｏ４的形式存在，它们之间无交互作用，但都与铁有交互作用．铜钴比和浸铁都影响催化剂的还原性质，浸铁不影响Ｃｏ３Ｏ４而影响ＣｕＯ，浸铁后催化剂中ＣｕＯ的还原要难于浸铁前，而α－Ｆｅ２Ｏ３的还原则恰恰相反．The phase of the catalyst for synthetising higher alchole is analysized by XRD and IR.The component Cu and Co in catalyst exists as CuO and Co 3O 4 respectively.Cu and Co do not effect each other,but both of them are effected by Fe.The ratio of Cu and Co and the soaking Fe effect the reductivity of the catalyst.Soaking Fe effects CuO but does not effect Co 3O 4.After soaking Fe,the CuO in the catalyst get more difficult to be reduced and the α Fe 2O 3 get easier to be reduced.
