[Chemical Knowledge]：Difference between benzoic acid benzene alcohol and phenol

Read： 577 Time：18months ago Source：Transform the World with Simplicity

Benzoyl benzoate and phenol are two common compounds, which have certain differences in structure and properties.

from the chemical structure point of view, the molecular structure of benzoic acid benzene alcohol contains benzene ring and hydroxyl (-OH) group, while the molecular structure of phenol contains only benzene ring and hydroxyl (-OH) group. This is one of their most striking differences. Benzoyl alcohol contains carboxyl (-COOH) and hydroxyl (-OH) groups in its structure, which makes its molecule more complex.

in terms of physical properties, benzoyl alcohol is a solid with a higher melting point, while phenol is a liquid with a lower melting point. This is because the molecular structure of benzoic acid benzene alcohol is more complex, the interaction force between molecules is strong, resulting in its solid state properties are more stable.

again, from a chemical point of view, benzoic acid and phenol have some different reaction characteristics. Benzoyl alcohol can react with alkali to produce the corresponding benzoate, while phenol can react with acid to produce the corresponding phenolate. In addition, benzoic acid benzene alcohol can also be esterified, and phenol can be electrophilic substitution reaction.

In addition, the differences in application are also significant. Phenol is commonly used as an industrial raw material and solvent due to its lower melting point and volatile nature. Because of its high melting point and stable properties, benzoic acid benzene alcohol is commonly used in the field of medicine preservatives, antioxidants and so on.

sum up, benzoic acid and phenol in the structure, physical properties, chemical properties and applications have obvious differences. Understanding these differences helps us to choose the right compound in the right scenario and to understand its properties and uses.
