| application field | benzene is one of the important chemical raw materials, which can be used to prepare dyes, pesticides, plastics, resins, synthetic rubber, synthetic fiber, synthetic detergent, synthetic agent, varnish, etc. (see figure 3). FIG. 3 is a graph showing the utilization of benzene. benzene is also an indispensable solvent and raw material for fine chemicals. Can be substituted, alkylation, acylation, addition, halogenation, nitration, sulfonation, oxidation, hydrogenation and other reactions to prepare a variety of benzene derivatives, such as chlorobenzene, nitrobenzene, phenol and ethylbenzene, these derivatives are important intermediates, widely used in spices, detergents, food additives, surfactants, emulsifiers, dyes, pigments, plastics, rubber, coatings, adhesives, plasticizers, polymerization initiators, pesticides, medicine, explosives, synthetic resins, solvents, lubricants, etc. benzene is a good solvent for rubber, fats and many resins, which is gradually replaced by other solvents due to its high toxicity. Benzene can be added to gasoline to improve its anti-knock performance, and can also be used as a high octane number of automobile fuel. by the 1950s, benzene was almost entirely separated from the light oil fraction of coke oven gas and coal tar. In recent years, benzene is mainly obtained from the catalytic reforming of certain fractions of petroleum (e. G. Naphtha, also known as crude gasoline). Benzene can also be prepared by disproportionation of toluene or dealkylation of alkyl benzenes. In the developed countries of petrochemical industry, benzene is mainly derived from the aromatization process of petroleum processing, or from crude benzene refining in coking industry, the latter is specifically referred to as coking benzene (see light benzene pickling and catalytic hydrogenation of light benzene). All large coking plants in China produce coking benzene. China will be divided into the coking benzene with benzene, benzene and benzene with solvent. |
