In our daily life, we often hear the words alcohol and glycol. Although the two are pronounced similarly, they actually refer to different substances. Next, we will detail and compare the difference between alcohol and glycol to help readers better understand the difference between the two.

alcohols are a class of organic compounds that contain one or more hydroxyl (-OH) functional groups in the molecule. According to the number of hydroxyl groups, alcohols can be divided into monoalcohols, diols, triols, etc. Diols, on the other hand, are a specific type of alcohol that contains two hydroxyl functional groups in the molecule.

alcohols and glycols have some differences in chemical structure. The hydroxyl functional group in the alcohol molecule is attached to the carbon chain, while the two hydroxyl functional groups in the diol molecule can be attached to the same carbon atom or to different carbon atoms. This structural difference leads to differences in the properties of the alcohol and the diol.

alcohols and glycols differ in physical properties due to structural differences. In the case of alcohols, for example, since monoalcohols, diols and triols contain different amounts of hydroxyl functional groups, their physical properties such as boiling point, melting point and solubility will vary. For diols, the physical properties may be somewhat different from those of monoalcohols due to the presence of two hydroxyl functional groups in the molecule. For example, the boiling and melting points of ethylene glycol are relatively low, and it has a high solubility.

In addition, alcohols and glycols also differ in chemical properties. Alcohol is a kind of widely used organic solvent, which plays the role of dissolution, solvent and catalyst in chemical reaction. The glycol is widely used in industrial production, such as ethylene glycol is often used as a solvent, pigment, paint and so on. There are also differences in reactivity between alcohols and diols. Because the diol molecule contains two hydroxyl functional groups, they may exhibit special chemical properties in some reactions.

In summary, alcohols and glycols have some differences in chemical structure, physical properties and chemical properties. Alcohols are a class of organic compounds, and glycols are a specific class of alcohols. For us, understanding the difference between alcohol and glycol helps us to better understand the differences and characteristics of the two in practical applications. It is hoped that this article can provide readers with some valuable information to increase their understanding of alcohols and glycols.
