Toluene is used in large quantities as a solvent and as an additive for high-octane gasoline, and is also an important raw material for organic chemicals. However, compared with benzene and xylene, which are obtained from coal and petroleum at the same time, the current production is relatively excess, so a considerable amount of toluene is used for dehydration. Alkylation to benzene or disproportionation to xylene. A series of intermediates derived from toluene, widely used in the production of fine chemicals such as dyes; medicine; pesticides; explosives; auxiliaries; spices, etc., and also used in the synthetic material industry. Benzyl chloride obtained by chlorination of the side chain of toluene; benzyl dichloride and benzyl trichloride, including their derivatives benzyl alcohol; benzaldehyde and benzoyl chloride (generally obtained from phosgenation of benzoic acid), in medicine; pesticides ; Dyes, especially in the synthesis of spices are widely used. The cyclic chlorination products of toluene are pesticides; medicines; intermediates of dyes. Toluene is oxidized to obtain benzoic acid, which is an important food preservative (mainly using its sodium salt) and also used as an intermediate in organic synthesis. Intermediates obtained by sulfonation of toluene and benzene derivatives, including p-toluenesulfonic acid and its sodium salt; CLT acid; toluene-2,4-disulfonic acid; benzaldehyde-2,4-disulfonic acid; toluenesulfonic acid Acid chloride, etc., used in detergent additives, fertilizer anti-caking additives; organic pigments; pharmaceuticals; dye production. The nitration of toluene produces a large number of intermediates. Many end-products can be derived, which are extremely important in polyurethane products; dyes and organic pigments; rubber additives; medicine; explosives, etc.
