Ethyl acetate and ethyl alcohol are two common organic compounds, which are widely used in chemical industry, medicine, coating and other fields. So, what is the difference between the two?

from the chemical structure, the chemical formula of ethyl acetate is CH3COOC2H5, while the chemical formula of ethyl acetate is C4H10O2. It can be seen that their molecular structures are not the same, ethyl acetate contains an ester group, while ethyl acetate contains an ether bond.

In terms of physical properties, ethyl acetate is a colorless and transparent liquid with a pungent odor, flammable, soluble in organic solvents such as ethanol and ether, and insoluble in water. Ethanol ethyl ester is also a colorless liquid, but has a fruity taste. It is a low-toxic alcohol ether exchange solvent and can be miscible with water. Therefore, in storage and use, special attention should be paid to fire and explosion prevention.

In addition, from the use point of view, ethyl acetate is mainly used for the preparation of coatings, glue, ink, paint and other chemical products, can also be used as an organic solvent. Ethanol ethyl ester is mainly used in medicine, flavors, plastics and other fields, and can also be used as a solvent and extractant.

in chemical properties, the vapor of ethyl acetate and air will form an explosive mixture, flammable. The vapor of ethyl alcohol is lighter, volatile, and has an alcohol smell. Therefore, it is necessary to pay attention to ventilation during use to prevent vapor accumulation from causing an explosion.

To sum up, ethyl acetate and ethyl alcohol have obvious differences in chemical structure, physical properties, uses and chemical properties. When choosing to use, it is necessary to distinguish according to the specific situation to ensure the safe and effective use of these two chemicals.
