研究了混合氧化物Cu1-xCo2+xO4作为丙烯氧化催化剂的结构和催化性能。在八面体和四面体中发现阳离子重分配。结果表明，当x < 0.70时，尖晶石呈正态分布，当x < 0.70时，尖晶石呈部分反态分布。用脉冲法测定丙烯醛的活性和选择性，则遵循相反的趋势。没有发现阳离子催化性能之间的可加性。表面Cu+浓度是通过烯丙基过程合成丙烯醛的原因的假设似乎是正确的。
The structural and catalytic properties of mixed oxides Cu1-xCo2+xO4, which are propene oxidation catalysts, have been studied. Cationic repartition in the octahedral and tetrahedral sites is found. The results indicate that, for x 0.70, the spinels are normal, and for x < 0.70, the spinels are partially inverse. Activities and selectivities for acrolein, determined by the pulse method, follow opposite trends. Additivity between the cationic catalytic properties is not found. The assumption that the surface Cu+ concentration is responsible for acrolein synthesis via an allylic process appears to be correct.
