Chemical Properties of ethyl acetate solvent
CAS 141-78-6 ethyl acetate chemical has a remarkable ability for solvent action on both polar and nonpolar substances. This material is very combustible and displays high rates of evaporation. In addition, it can be dissolved in almost all organic solvents, including alcohols, ethers, and ketones, while remaining nearly insoluble in water. These characteristics support numerous purposes of this solvent in the industrial and chemical fields.
