In organic synthesis, p-benzoquinone is used as a hydrogen acceptor (dehydrogenator) and an oxidizing agent. It can also participate in the Diels-Alder reaction as a dienophile. The derivatives of p-benzoquinone are treated and sulfuric acid to obtain 1,2, 4-phenyltritriacetate derivatives. This reaction was first described by Thiele in 1898, hence the name Thiele reaction. Chemical properties Yellow crystal. Combustible. Melting point 116ºC, relative density 1.318 (20/4ºC), soluble in ethanol, ether and alkali, slightly soluble in water. Can sublimate. Its vapor is volatile and partially decomposed. Has a pungent odor similar. Uses Intermediates for dyes and pharmaceuticals. rubber antioxidants, polymerization initiators and oxidants. Uses P-benzoquinone can be used to produce , used as dyes and pharmaceutical intermediates, rubber antioxidant, anti-polymerization Chemicalbook agent, antioxidant, developer, etc. In organic synthesis, dienophiles used in the cycloaddition of Diels-Alder to form naphthoquinones and 1, 4-phenadione. Use for the qualitative determination of coniferine, azecyclocene, tyrosine . The analysis is used for the determination of amino acids. 99% and 99.5% high purity grades are used for the photometric determination of amines. It is dissolved in dilute sulfuric acid, oxidized by manganese dioxide, separated and purified by steam distillation, crystallized, dehydrated and dried to obtain the finished product. In industrial production, this process is also an intermediate step , and in some cases, such as reagent production drug manufacturing,. Raw material consumption quota:  2000kg/t, sulfuric acid (93%) 8500kg/t, manganese ore powder (containing manganese 60-65%) 9500kg/t.
