Infobox references

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.[2]

## Preparation

Cerium acetate can be prepared by reacting cerium(III) carbonate and 50% acetic acid in an aqueous solution:[3]

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.[4] 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.[2]
