Mô tả

Caesium carbonate (or cesium carbonate in the US) is a white crystalline solid compound. Caesium carbonate has a high solubility in polar solvents such as water, alcohol, Et₂O, and DMF. Its solubility is higher in organic solvents compared to other carbonates like potassium carbonate. It is important base for organic chemistry to synthesize various compounds. Caesium carbonate is insoluble in most other organic solvents such as toluene, p-xylene, and chlorobenzene.
