On the analysis of the boiling point of ethyl acetate and water azeotrope
The nature of the material is related to the image of azeotrope. The study of the boiling point of the azeotrope formed by ethyl acetate and water is the gist of chemistry.
Guanfu ethyl acetate has unique characteristics. Water is also the source of all things. The two are mixed, and the azeotropic state is different. For azeotrope, at a specific temperature, the composition of the liquid phase and the gas phase is constant, and its boiling point is different from that of pure ethyl acetate and water.
The reason is that the force between molecules is the key. The molecule of ethyl acetate interacts with water molecules, or there is a hydrogen bond, or it has a change of van der Waals force. This interaction changes the gas-liquid equilibrium and leads to the emergence of azeotropic phenomenon.
After many experiments, the boiling point of the azeotrope of ethyl acetate and water is determined and different from the pure boiling point of the two. This boiling point value is important in the fields of chemical industry, scientific research and other fields. In the separation and purification of boiling points, according to this boiling point, subtle methods can be devised to effectively separate ethyl acetate from water.
Or distillation, the temperature is controlled near the azeotropic boiling point, the gas phase enriches the azeotrope composition, and after condensation, the two can be divided one by one. Or supplemented by other methods, such as adding specific reagents, changing the intermolecular interaction, adjusting the azeotrope property, and then optimizing the separation effect.
In short, the study of the boiling point of ethyl acetate and water azeotrope has far-reaching implications in the theory of chemistry and the technology of industry.
