How do you make cerium oxide?

Synthesis of Cerium−Oleate Complex (1). The cerium−oleate complex was prepared by reacting sodium oleate (12.2 g, 40.5 mmol) with cerium chloride heptahydrate (5.0 g, 13.5 mmol) in mixture solvent (40 mL of ethanol + 30 mL of water + 70 mL of hexane) at 70 °C for 4 h.
