Ethylene ether and diethyl ether are two common organic compounds, which have a wide range of applications in the chemical industry. But many people tend to confuse the two substances or even think they are the same compound. In fact, diethyl ether and diethyl ether have obvious differences in chemical structure and properties. The chemical name of

ethyl diether is ethyl dioxide, the chemical formula is C4H10O2, the molecular weight is 90.12, is a colorless flammable liquid, with a low boiling point and ignition point, widely used in organic synthesis and solvent extraction and other industrial fields. The chemical name of diethyl ether is 1,1-diethyl ether, the chemical formula is C4H10O, and the molecular weight is 74.12. It is also a colorless liquid, but it is different from ethyl ether in structure and properties.

ethylene ether is a symmetrical glycol ether, its molecule contains two oxygen atoms, and the bond between oxygen atoms and carbon atoms is two C- O-C bonds, the structure is relatively stable. Diethyl ether, on the other hand, is an asymmetric glycol ether that contains only one oxygen atom and one C- O-C bond and is relatively unstable in structure. This also allows ethyl ether to provide double oxygen atoms in chemical reactions, while diethyl ether can only provide single oxygen atoms, so the scope of application in chemical production is different.

In addition, ethyl ether is more toxic, flammable and explosive, and has certain hazards to the human body and the environment, so it needs to be used with caution. Diethyl ether is relatively good in toxicity and stability, and is less harmful to human body and environment. Therefore, in industrial production, diethyl ether is also more valued.

To sum up, there are obvious differences between ethyl ether and diethyl ether in chemical structure, properties and applications. Understanding these differences not only helps us to better select and use these two compounds, but also effectively avoids safety incidents caused by confusion. It is hoped that this article can help readers to better understand ethyl ether and diethyl ether and avoid unnecessary risks in work and life.
