ABSTRACT:
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.
