【摘要】 结合稀土盐在乙二醇单乙酸醋酸酯合成反应中的催化特性和反应的动力学行为，利用Ｘ—射线衍射（ＸＲＤ）。程序升温分解（ＴＰＤＥ），程序升温脱附（ＴＰＤ）等手段，对稀土盐催化剂的结构特征进行了系统的研究，将所得结果与催化反应动力学规律相关联，对稀土盐在酯化反应中的催化作用进行了分析。更多还原

【Abstract】 Catalytic characteristic of rare-earth salt in the synthesis or 2-ethoxyethanol acetate and the kinetic behavior of the synthesis have been investigated. In addition,the structural characteristic of rare-earth salt catalyst is systematically studied by X-ray diffraction(XRD), temperature programmed decomposition(TPDE) and temperature programmed desorption(TPD). By correlating the results from structural analysis with the activity of catalytic reaction and kinetic rule of reaction, the catalysis of rare-earth salt in the esterificayion is discussed.更多还原
