1, hydroquinone is mainly used as a photographic developer. Hydroquinone and its alkylates are widely used as inhibitors added during monomer storage and transportation, with a common concentration of about 200ppm. [1]
2, used as rubber and gasoline antioxidant, etc. [1]
3, in the field of treatment, the hydroquinone is added to the hot water and cooling water of the closed circuit heating and cooling system, which can inhibit the corrosion of the water-side metal. Hydroquinone is a deoxidizer of furnace water to which hydroquinone is added during boiler water preheating and deoxidizing to remove residual dissolved oxygen.
4, is the manufacture of anthraquinone dyes, azo dyes, pharmaceutical raw materials. [1]
5, used as detergents corrosion inhibitor, stabilizer and antioxidant, but also used in cosmetics hair dye.
6, photometric determination of phosphorus, magnesium, niobium, copper, silicon and arsenic. Polarographic and volumetric determination of iridium. Reducing agent of heteropoly acid, reducing agent of copper and gold
