Basic Chemical Raw Materials Benzene CAS:71-43-2

Benzene is the simplest aromatic hydrocarbon with the formula C6H6. In 1865, the German chemist F.A. Kekule proposed that benzene has a hexagonal structural formula with alternating arrangements of single and double bonds, which has been used ever since.

In a benzene molecule, six carbon atoms and six hydrogen atoms are on the same plane, forming a regular hexagon. The bond is the same, and the bond Angle is 120 degrees. Each carbon atom in a benzene molecule is sp2 hybridized, and the unhybridized p orbitals on each carbon atom are parallel to each other (perpendicular to the plane where the benzene ring is located), overlapping to form a closed conjugated system. Benzene is an important chemical raw material because of its closed conjugated system in the molecule, which is different from the general olefin and has special properties. From benzene can be prepared polystyrene plastics, styrene butadiene rubber, synthetic detergents, synthetic drugs, dyes and pesticides and so on.

Benzene is chemically stable, aromatic, and prone to substitution reactions - halogenation, nitration, sulfonation, and Fourier reaction. Addition reaction can occur under appropriate conditions. Not oxidized by potassium permanganate and other oxidants; At high temperatures, in the presence of vanadium pentoxide, it can be oxidized to maleic anhydride by air. 1. Substitution reactions with Chemicalbook halogens can occur under iron catalysis: C6H6+Cl2= (Fe catalyst) =C6H5Cl+HCl. 2. Benzene is co-heated with the mixed acid of concentrated nitric acid and concentrated sulfuric acid to generate nitrobenzene: C6H6+HNO3= (concentrated H2SO4) =C6H5NO2+H2O. 3, benzene and concentrated sulfuric acid co-heat to generate benzene sulfonic acid.

One of the most important basic organic chemical raw materials. Benzene through the substitution reaction, addition reaction and benzene ring rupture reaction, can be derived from many important chemical intermediates, is the production of synthetic resin, plastic, synthetic fiber, rubber, detergent, dyes, medicine, pesticides, explosives and other important basic raw materials. Benzene is also widely used as a solvent and as an admixture to increase the octane number of gasoline in the oil refining industry.
