讨论了镧的置換度和稀土元素对含氧有机化合物在杂多酸催化剂上的氧化反应的影响,并与催化剂的结构进行了关联。镧的引入不影响氧化脱氢反应,而明显削弱插入氧反应。其它稀土元素的影响与镧相同。
The effects of the substitution degree of lanthanum and rare earth elements on the oxidation reaction of the oxygen-containing organic compounds on the heteropolyacid catalysts are discussed, and the relationship between them and the structure of the catalysts is also discussed. The introduction of lanthanum does not affect the oxidative dehydrogenation reaction, but significantly weakens the insertion oxygen reaction. Other rare earth elements have the same effect as lanthanum.
