[Chemical Knowledge]：Difference Between Phenol and Benzyl Alcohol

Read： 713 Time：19months ago Source：Transform the World with Simplicity

Phenol and benzyl alcohol are two common chemicals, which are widely used in industrial production and scientific research. Although they are all derivatives of benzene, there are some obvious differences in chemical structure and properties. Next, we will distinguish between phenol and benzyl alcohol by chemical structure, physical properties and uses.

chemical structure
Phenol, whose chemical structure is C6H5OH, is an organic compound, also known as hydroxybenzene. Its molecule contains a benzene ring and a hydroxyl group. The chemical structure of benzyl alcohol is C6H5CH2OH, which is also an organic compound containing a benzene ring and a hydroxyl group. It can be seen that the difference is that the hydroxyl group in phenol is directly attached to the benzene ring, while the hydroxyl group in benzyl alcohol is attached to one methyl group of the benzene ring.

physical properties
phenol is a white crystalline solid, has a special phenol taste, insoluble in water, soluble in ethanol and ether and other organic solvents. It has a low melting point and is a transparent liquid after melting. Benzyl alcohol is also a white crystalline solid, but it has good solubility and can be dissolved in water and most organic solvents. Its melting point is relatively low, transparent liquid.

USES
Due to the different chemical properties of phenol and benzyl alcohol, they have different uses in production. Phenol is mainly used in the preparation of phenolic resins, dyes, pharmaceuticals and pesticides, and can also be used as an industrial preservative. Benzyl alcohol is mainly used in medicine, spices, dyes and cosmetics, and has a certain bactericidal effect.

To sum up, although phenol and benzyl alcohol are somewhat similar in chemical structure, they have obvious differences in physical properties and uses. Therefore, in actual use, it is necessary to select appropriate chemical substances according to specific requirements and application scenarios. I hope this article can help you better understand and distinguish between phenol and benzyl alcohol, and provide some help for your work and study.
