Description: Quinone (p-benzoquinone) exists as a large yellow, monoclinic prism with an irritating odour resembling that of chlorine. Quinone is extensively used as a chemical intermediate, a polymerisation inhibitor, an oxidising agent, a photographic chemical, a tanning agent, and a chemical reagent. Quinone (p-benzoquinone) was first produced commercially in 1919 and has since been manufactured in several European countries. 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. Occupational exposure to quinone may occur in the dye, textile, chemical, tanning, and cosmetic industries. Inhalation exposure to quinone may, occur, from tobacco smoke.
