N2 - Doping Li/MgO with Sn leads to an active, selective and stable catalyst. The formation of Li2Mg3SnO6 seems to be responsible for the improved properties. Li2Mg3SnO6 has a cubic structure like MgO. This paper shows that doping Li/MgO with Zr can result in the formation of various mixed oxides with different catalytic properties. The results indicate that Li2CO3 is essential to obtain a good selectivity and activity when Li2MgZrO4 is present in Li/Zr/MgO catalysts. When Li2Mg3ZrO6 is present, without detectable amounts of Li2CO3, the activity and selectivity remain at a high level, resulting in relatively high yields, like the results for the Li2Mg3SnO6 containing Li/Sn/MgO catalyst.
