A new heterogeneous catalyst system for the cross-metathesis of methyl oleate with ethylene was investigated based on methyltrioxorhenium (MTO) grafted on the spinel-type mesoporous ZnAl₂O₄ in the absence of chloride for the first time. NH₃ TPD spectra revealed that the number of Lewis acid sites of ZnAl₂O₄ decreased significantly after MTO grafting, thereby demonstrating that the Lewis acid sites of the ZnAl₂O₄ support are involved in the binding to MTO. Notably, the MTO grafted on ZnAl₂O₄ catalyst exhibited a good catalytic activity, producing only the desired cross-metathesis products of 1-decene and methyl 9-decenoate.

基于在不存在氯化物的情况下，在尖晶石型介孔ZnAl ₂ O ₄上接枝的甲基三氧or（MTO），研究了一种新的非均相催化剂体系，用于油酸甲酯与乙烯的交叉复分解。NH ₃ TPD光谱表明，在MTO接枝后，ZnAl ₂ O ₄的Lewis酸位明显减少，从而表明ZnAl ₂ O ₄载体的Lewis酸位参与了与MTO的结合。值得注意的是，MTO接枝在ZnAl ₂ O _4上 催化剂表现出良好的催化活性，仅产生所需的1-癸烯和9-癸烯酸甲酯的交叉复分解产物。
