Benzene is pure benzene. Benzene is a chemical substance. Its formula is C6H6. It is one of the most important basic organic raw materials and a representative of aromatic hydrocarbons. It has a relatively stable six-membered ring structure. With high refraction and strong aroma, flammable, toxic. Miscible with ethanol, ether, acetone, carbon tetrachloride, carbon disulfide and acetic acid, slightly soluble in water. It is not corrosive to metals, but sulfur containing impurities in lower grades of benzene have obvious corrosion effects on copper and some metals. Liquid benzene has a degreasing effect and can be absorbed by the skin and poisoned, so contact with the skin should be avoided.
Benzene is widely used in the production of synthetic rubber, synthetic resin, synthetic fiber, organic pigments, synthetic detergent and dyes, medicine, spices, pesticides, etc., and is often used in heat carriers and solvents. Benzene is a common solvent in industry, mainly used for metal degreasing. Its most important use is to synthesize a series of benzene derivatives as chemical raw materials: the raw materials for the production of plastics, rubber, detergents, fibers, dyes, pesticides, etc., usually contain various compounds generated by benzene through substitution reactions, addition reactions, oxidation reactions, etc. Benzene can also be used to make benzene intermediates: benzene and ethylene to form ethylbenzene, so as to produce styrene for plastics; Benzene and propylene form isopropylbenzene, thereby producing acetone and phenol for resins and adhesives; There are also cyclohexane for the manufacture of nylon, maleic anhydride, nitrobenzene for the production of aniline, chlorobenzene, various alkyl benzene and hydroquinone, anthraquinone and other chemical products for the production of detergents and additives.
