The functional group contained in ethyl acetate is an ester group (− COO −). The existence of the ester group endows ethyl acetate with unique chemical and physical properties. Its chemical properties are relatively active, and hydrolysis reactions can occur under certain conditions. During hydrolysis, in an acidic or alkaline environment, the ester group will break and react with water to generate corresponding acids and alcohols. In terms of physical properties, ethyl acetate has a special odor and shows different characteristics from other functional group compounds in terms of solubility. It is insoluble in water and miscible with most organic solvents. This special functional group structure determines that ethyl acetate has a wide range of applications in organic synthesis, fragrance preparation and many other fields.
