CaOEt2

CaOEt2, also known as calcium ethoxide or calcium ethylate, is an organometallic compound with the chemical formula Ca(OC2H5)2. It is a salt formed from the reaction of calcium and ethanol. In its pure form, it is a white solid. It is sensitive to moisture and air, readily hydrolyzing in the presence of water to form calcium hydroxide and ethanol. This reactivity necessitates storage under an inert atmosphere.

Calcium ethoxide is primarily used as a catalyst in organic synthesis, particularly in transesterification reactions, which are important in the production of biodiesel. It can also serve as a source of calcium ions in various chemical processes. Its solubility in organic solvents depends on the specific solvent and the presence of any co-solvents. Due to its basic nature, it can also act as a strong base in certain organic transformations. Care should be taken when handling CaOEt2 as it is an irritant and should be kept away from moisture.
