Production of Para Benzoquinone
Process of producing p-benzoquinone, wherein hydroquinone and hydrogen peroxide are reacted in water, an aqueous inorganic acid solution, an inert organic polar solvent or a mixture of water with an inert organic polar solvent in the presence of a catalyst selected from the group consisting of iodine, hydrogen iodide, and iodine compounds of metals. According to the process, p-benzoquinone can be obtained from hydroquinone with the yield and the quality of the p-benzoquinone being high without requiring any special facilities, equipments and operations.

Quinone is extensively used as a chemical intermediate, a polymerisation inhibitor, an oxidising agent, a photographic chemical, a tanning agent, and a chemical reagent. Its major use is in hydroquinone production, but it is also used as a polymerisation inhibitor and as an intermediate in the production of a variety of substances, including rubber accelerators and oxidising agents. It is used in the dye, textile, chemical, tanning, and cosmetic industries. In chemical synthesis for hydroquinone and other chemicals, quinone is used as an intermediate. It is also used in the manufacturing industries and chemical laboratory associated with protein fibre, photographic film, hydrogen peroxide, and gelatin making.
