Ethyl acetate and ethyl acetate are two common organic compounds, which have some differences in chemical structure, properties and applications. Below we will compare these two compounds in detail in terms of structure, physical properties, chemical properties and applications.

1. structural differences
the chemical name of ethyl acetate is vinyl acetate, the molecular formula is C4H8O2, and the structural formula is CH3COOCH2CH3; while the chemical name of ethyl acetate is ethyl acetate, the molecular formula is also C4H8O2, and the structural formula is CH3CH2OOCCH3. From the structural point of view, the structure of ethyl acetate contains a vinyl group, and the structure of ethyl acetate contains an ethyl group, which is the key to the difference between the two.

2. physical properties
1. Appearance: ethyl acetate is a colorless liquid with a special smell. ethyl acetate is also a colorless liquid, but the smell is slightly different.
2. Boiling point: the boiling point of ethyl acetate is 77 ℃, and the boiling point of ethyl acetate is 77.1 ℃.
3. Density: The density of ethyl acetate is 0.93 g/cm and that of ethyl acetate is 0.90 g/cm.

3. chemical properties
acetic acid ethyl ester and acetic acid ethyl ester also have some differences in chemical properties. Due to the different molecular structure of the two, they are different in solubility, acid and alkali, and then have an impact on their characteristics and uses in practical applications. Ethyl acetate is generally used in ink, paint, dye, plastic and other industries, while ethyl acetate is mainly used in solvents, drugs and spices. This is also the difference between them.

4. Applications
Ethyl acetate and ethyl acetate have different applications in industry and daily life. As an organic solvent, ethyl acetate is widely used in ink, paint, dye, plastic and other industries. The ethyl acetate is more used in medicine, spices and daily chemicals, such as pharmaceuticals, incense and so on.

To sum up, although ethyl acetate and ethyl acetate are somewhat similar in nomenclature, there are obvious differences in their structure, physical properties, chemical properties and application fields. Understanding these differences will help us to better select and use these two compounds, as well as obtain better application results in related fields.
