Boiling point of benzyl alcohol

The boiling point of benzyl alcohol is about 205℃, and the relevant knowledge is as follows:

1, benzyl alcohol, chemical formula is C7H8O, colorless liquid, with special fragrance. It is an important raw material for many organic compounds and is widely used in chemical industry, medicine, spices and other fields. The boiling point of benzyl alcohol is an important physical property, which is of great significance to its processing, storage and use.

2. The boiling point of benzyl alcohol refers to the temperature at which benzyl alcohol changes from liquid to gas under a certain pressure. According to the experimental determination, the boiling point of benzyl alcohol is about 205℃. This means that at normal pressure, benzyl alcohol needs to be heated to 205℃ to boil. However, in the actual production process, in order to improve production efficiency and save energy, vacuum distillation is usually used to increase the boiling point of benzyl alcohol.

3. The boiling point of benzyl alcohol is closely related to its molecular structure. The existence of benzene ring makes benzyl alcohol have high stability, while the introduction of hydroxyl group (-OH) reduces the intermolecular interaction of benzyl alcohol and makes its boiling point relatively low. In addition, the purity of benzyl alcohol will also affect its boiling point. The boiling point of high-purity benzyl alcohol is higher, while the boiling point of benzyl alcohol containing impurities will decrease.

4. Understanding the boiling point of benzyl alcohol is of great significance to its processing and application. Firstly, by controlling the heating temperature, the evaporation and concentration of benzyl alcohol can be effectively realized. Secondly, in the pharmaceutical industry, benzyl alcohol is often used as a solvent and preservative for drugs, and its boiling point is very important to ensure the stability and effectiveness of drugs.

Knowledge of benzyl alcohol

Benzyl alcohol, also known as benzyl alcohol, is an organic compound with the chemical formula of C7H8O. It is a colorless liquid with a special smell, which is soluble in water and most organic solvents. Benzyl alcohol is widely used in chemical industry, medicine, spices and other fields.

2. The preparation methods of benzyl alcohol are mainly as follows: benzaldehyde reacts with sodium hydroxide; Is produced by esterification of benzoic acid and methanol; It is produced by the reaction of anisole and sodium hydroxide. Among them, the first method is the most commonly used preparation method in industry.

3. Benzyl alcohol is mainly used as solvent, catalyst and intermediate in the chemical field. For example, it can be used as an important raw material for synthesizing resins, plastics, rubber, dyes and other chemicals. In addition, benzyl alcohol can also be used to prepare essence, medicine and other organic compounds.

4. In the field of medicine, benzyl alcohol has antibacterial, anti-inflammatory and analgesic effects, and is often used to treat diseases such as dermatosis and toothache. In addition, benzyl alcohol can also be used as a drug carrier to improve the stability and bioavailability of drugs. In the field of spices, benzyl alcohol is an important essence component with a sweet aroma.
