Difference between Hydrobenzene and Benzene

Hydrogenated benzene (Hydrogenated Benzene) plays an irreplaceable role as an important intermediate in the petrochemical industry. This article will analyze the difference between hydrobenzene and benzene in depth, discuss its important role in petroleum refining, and its application in other industrial fields.

1. Hydrogenated Benzene Definition and Properties

Hydrogenated benzene is a product of benzene through catalytic hydrogenation reaction. All carbon-carbon double bonds in its molecular structure are saturated, and double bonds no longer exist in the molecule. This structural change resulted in a significant change in the physical properties of hydrobenzene: the color changed from a deep orange to a colorless transparent liquid, the density decreased from 0.805g/cm³ of benzene to about 0DOMA (assuming 0.88g/cm³), and the solubility was significantly improved. Compared with benzene, the solubility in water can reach 100mol/kg.

The chemical properties of hydrobenzene have also changed significantly. The benzene ring structure in benzene makes it have a strong aromatic odor and strong toxicity, while hydrobenzene has a colorless and odorless chemical properties, avoiding the dangerous characteristics of benzene. Hydrobenzene exhibits excellent stability in many chemical reactions, making it an important intermediate.

2. Hydrogenated Benzene Production

The production process of hydrobenzene is to convert liquid benzene into hydrobenzene through catalytic hydrogenation reaction. This reaction needs to be carried out under the condition of high temperature and high pressure. Graphite is usually used as a catalyst to obtain liquid benzene through benzene fractionation in liquefied petroleum gas, and then it is converted into hydrobenzene through a catalytic hydrogenation unit.

Compared with benzene, the production process of hydrobenzene requires higher temperature and pressure, but this is determined by the physical properties of benzene. The formation process of hydrobenzene not only improves the physical stability of benzene, but also greatly prolongs its service life in petrochemical industry.

3. Hydrogenated Benzene

Hydrogenated benzene has important application value in petroleum refining. As an important intermediate in the petroleum refining process, hydrobenzene plays a key role in various stages of petroleum processing. For example, in the catalytic cracking process, the formation of hydrobenzene can significantly improve the quality of petroleum products and reduce the formation of harmful substances.

Hydrogenated benzene also has a wide range of applications in the field of fine chemicals. For example, in organic chemical synthesis, hydrobenzene can be used as an important solvent and catalyst to help synthesize various high value-added chemical products.

4. Hydrogenated Benzene and Other Similar Substances

The difference between hydrobenzenes and benzene is not only reflected in the physical and chemical properties, but also in their use in industrial applications. For example, graphitic benzene is a substance obtained by the catalytic hydrogenation of benzene by graphite. Its physical properties are similar to that of hydrobenzene, but its chemical properties are more active and are often used in some special industrial applications.

The liquefied petroleum gas benzene (LPPB) is one of the main components of liquefied petroleum gas, its physical properties are similar to hydrobenzene, but its chemical properties are more active, often used in some specific industrial applications.

The high solubility and colorless and odorless character of hydrobenzene make it an ideal solvent for many fine chemical products. Its application in petroleum refining also shows great potential, especially in the reduction of petroleum product impurities, hydrobenzenes play an increasingly important role.

Domina Conclusions

Hydrobenzene, as an important intermediate in petroleum refining, has unique physical and chemical properties and wide application value. Compared with benzene, hydrobenzene has the advantages of colorless, odorless, high solubility, and excellent stability in the catalytic hydrogenation reaction. Its application in petroleum refining, fine chemicals and other fields provides important technical support for industrial production. In the future, with the continuous progress of petrochemical technology, the use and importance of hydrobenzene will be further expanded.
