    • A process is provided for preparing ceric alkoxides, which comprises reacting ceric ammonium nitrate complexed with and in solution in ethylene or propylene glycol ether or tetrahydrofuran with an anhydrous alkali metal alkoxide at a temperature within the range from about -30.degree. C. to about 200.degree. C., preferably from 0.degree. to about 150.degree. C., until ceric alkoxide and the nitrate salt of the base are formed; the nitrate formed during the reaction is insoluble in the glycol ether and tetrahydrofuran and can be separated from the reaction mixture, and the cerium alkoxide when soluble in the glycol ether or tetrahydrofuran can be isolated from the solution pure, or as the complex with the alcohol or with the solvent, or in some cases the alkoxide can be used without separation from the reaction mixture in the presence of the nitrate.
    • 提供了一种制备二氧化铈的方法,其包括使与乙烯或丙二醇醚或四氢呋喃中的溶液中的和硝酸铈配合的硝酸铈铵与无水碱金属醇盐在约-30℃至约200℃的温度下反应 优选0℃至约150℃,直到形成了铈醇盐和碱的硝酸盐; 反应过程中形成的硝酸盐不溶于乙二醇醚和四氢呋喃,可与反应混合物分离,可溶于乙二醇醚或四氢呋喃中的醇盐可以从溶液中纯化,或作为与醇的络合物 或在一些情况下,在硝酸盐存在下,可以不用分离反应混合物使用醇盐。
