使用Cesium acetate is used in organic synthesis especially in Perkin reaction to prepare unsaturated cinnamic-type acids. It is used in petroleum drilling fluids as an alternative to cesium formate. In organometallic chemistry, it is an additive for metal-ctalyzed coupling reactions. It is also used in the inversion of stereo chemistry of secondary alcohols.

一般的な説明Cesium acetate is an inorganic salt. It has been reported to change the surface of kaolinite by undergoing intercalation under various reaction conditions. It modifies the catalytic activity of MCM (Mobil Composition of Matter) -41 and MCM-48-type mesoporous molecular sieves by undergoing ion exchange with cesium cations and impregnation on their surfaces.
