Toluene is widely used as a solvent and a high octane gasoline additive, and is also an important raw material for organic chemicals. At the same time, compared to benzene and xylene obtained from coal and petroleum, the current production is relatively surplus. Therefore, a considerable amount of toluene is used. Dealkylation to benzene or deuterated xylene.
Toluene-derived series of intermediates, widely used in dyes; medicine; pesticides; explosives; auxiliaries; perfumery and other fine chemicals production, but also for the synthetic materials industry.
Side-chain chlorination of toluene by monochlorobenzyl; dichlorobenzyl and trichlorobenzyl, including their derivatives benzyl alcohol; benzaldehyde and benzoyl chloride (generally also obtained from the phosgenation of benzoic acid), in medicine; pesticides Dyes, especially fragrances, are widely used in the synthesis.
The cyclochlorinated products of toluene are pesticides; pharmaceuticals; dye intermediates.
The oxidation of toluene to benzoic acid is an important food preservative (mainly using its sodium salt) and is 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; Acyl chloride, etc., used in detergent additives, fertilizer anti-caking additives, organic pigments, pharmaceuticals, dye production.
Nitration of toluene produces a large number of intermediates. Many final products can be derived, among which polyurethane products; dyes and organic pigments; rubber chemicals; medicines; explosives, etc. are the most important.
Toluene reacts with concentrated nitric acid to form trinitrotoluene (ie TNT).
