Benzene (C6H6) is produced as a by-product of petroleum industry. As well benzene can be produced from some other chemicals in a chemical laboratory and methods of benzene preparation are explained in detail in this tutorial.
Benzene can be prepared by several chemicals in the laboratory. But, we have to be careful when benzene is being produced due to it's toxicity. Therefore, follow safety protocols thoroughly to avoid short-time and longtime effects to the health.
Alkyne compounds such as acetylene (ethylene) polymerizes at high temperature to give arene compounds such as benzene.
Send Acetylene gas through a hot iron pipe. Here, benzene is prepared as a non aromatic compound. Three acetylene moles joins together in the hot iron tube with catalyst condensation. This reaction was first invented by Berthelot.
Benzoic acid is an aromatic carboxylic acid compound. When benzoic acid is mixed with soda lime or solid Sodium hydroxide and heated, Benzene is given as a carboxylic acid group reduction. A mixture of Calcium oxide and Sodium hydroxide is used as soda lime mixture.
Phenol is an aromatic alcohol compound. When Phenol is heated with Zinc dust, -OH group is eliminated and benzene is given as the product. Zinc is oxidized to Zinc oxide (ZnO) during this reaction.
Benzene diazonium chloride is an unstable compound at room temperature. However, Benzene diazonium chloride can be used to prepare benzene in two ways.
When Grignard reagent is exposed to water or dilute acid solution, Grignard reagent readily hydrolysis to respective alkane compound. In this reaction too, we use the same concept.
Hydrolysis of any phenyl magnesium halide in acidic medium will give benzene as the product. If dilute sulfuric acid and phenyl magnesium chloride are mixed together, benzene is given as the product.
Aryl halide compounds are defined as, when a halogen atom is directly joint to the benzene ring. Benzene is prepared by the reaction of chlorobenzene and Ni-Al alloy in the presence of Sodium hydroxide.
When Benzene sulphonic acid is heated with superheated steam (423K - 473K), benzene is given as a product. As a by-product, Sulfuric acid is formed.
Industrial preparation of benzene is based on the crude oil refining process.
Preparation of benzene by catalytic reforming is explained step by step.
In this process too, a catalytic conversion reaction is applied at medium temperature and medium pressure conditions.
Yes. Benzene is toxic compounds. It has benn found that benzene causes to cancers. Due to this toxicity of benzene, use of it is limited. Toluene is used instead of benzene.
According to the X-rays diffraction, it is found that shape of benzene is analogous hexagon. Bond angle of C-C-H is 1200C. All C-C bond lengths are same(0.139mm).
Question is not clear. As salts which contains a benzene group we can list sodium benzoate, sodium phenate.
