摘    要:制备了SO_4~(2-)/(ZrO_2-TiO_2-SnO_2)催化剂。以乙酸和乙醇的酯化为探针反应,试验表明,焙烧温度、焙烧时间和Zr:Ti:Sn原子比对催化活性有显著影响,其催化活性基本介于超强酸SO/TiO_2和SO/ZrO_2-TiO_2之间。(FT-IR)表明,SO以螯合状双配位的方式吸附在金属离子上,没有形成硫酸盐。XRD表明SO/(ZrO_2-TiO_2-SnO_2)呈非晶态。经研究推断SO/(ZrO_2-TiO_2-SnO_2)是超强酸。

关 键 词:SO_4~(2-)/(ZrO_2-TiO_2-SnO_2),超强酸制备,性能

Abstract:Aseries of (ZrO_2-TiO_2-SnO_2)catalysts that have not been reported are prcpared.Theiractivities for esterification reaction and physical properties are measured and tested in corre-lation with conditions of preparation. Results show that catalystic activities of well preparedcatalysts are comparable with that of and and can be affectedby calcination temperature and time as well as Zr:Ti:Sn atomic ratio,Results of XRD andFT-IR indicate that catalysts are non-crystalline and that iscombined with metal ions of catalvsts in a bidentate state instead of sulphates.So we inferthat the catalysts are solid superacids.
Keywords:superacid preparation  property
