Cerium acetate is an inorganic compound with the chemical formula of Ce(CH3COO)3. It is a white powder that is soluble in water. Its 1.5 hydrate loses water at 133°C to obtain an amorphous anhydrous form, and the amorphous phase changes to crystal at 212°C, and phase changes again at 286°C.
Preparation
Cerium acetate can be prepared by reacting cerium(III) carbonate and 50% acetic acid in an aqueous solution:《无机化合物制备手册》.朱文祥 主编. 化学工业出版社.第十四章 碳族元素.P512.XIV-124 醋酸铈(III)
: Ce2(CO3)3 + 6 CH3COOH → 2 Ce(CH3COO)3 + 3 H2O + 3 CO2↑
Properties
Cerium acetate is soluble in water and ethanol in its anhydrous form (its hydrate is insoluble in ethanol), easily soluble in pyridine, and insoluble in acetone.《无机化合物合成手册》.第二卷.日本化学会 编. 曹惠民 译. 化学工业出版社. 1988.7第一版.【1260】稀土元素的乙酸盐.P582 Its thermal decomposition at 310 °C will generate basic cerium(III) acetate, which will be further decomposed to obtain Ce2O2CO3 (a basic carbonate), and continued heating generates CeO2 and CO.Arii T, Kishi A, Ogawa M, et al.
