Study on the Rare Earth Solid Superacids SO₄^2-/TiO₂-Nd₂O₃ Catalyzed a-Pinene Isomerization

Abstract The preparation of the rare earth solid superacid SO₄^2-/TiO₂-Nd₂O₃ and a-pinene isomerization catalyzed by SO₄^2-/TiO₂-Nd₂O₃ were studied. The conditions for preparation of SO₄^2-/TiO₂-Nd₂O₃ and isomerization of a-pinene were optimized. It indicates that the catalyst has fair high catalytic activity and selectivity for a-pinene isomerization and the main product is camphene. The changes of structure and profile of SO₄^2-/TiO₂-Nd₂O₃ calcinated under different temperature were determined by IR, XRD and SEM.
Key words Rare earth solid superacid, a-Pinene, Isomerization

稀土固体超强酸催化a-蒎烯异构化反应

摘要 首次研究了稀土固体超强酸SO₄^2-/TiO₂-Nd₂O₃的制备及其催化a-蒎烯的异构化反应，得出最佳条件。结果表明，该催化剂对a-蒎烯的异构化反应具有很高的催化活性和选择性，主产物为莰烯。用IR、XRD、SEM等手段分析了不同焙烧温度的SO₄^2-/TiO₂-Nd₂O₃的结构和形貌变化。
