Hydroquinone USE

1. Hydroquinone is mainly used as a photographic developer.

2. Hydroquinone and its alkylates are widely used as polymerization inhibitors in the storage and transportation of monomers, and the concentration is usually around 200ppm.

3. Hydroquinone monomethyl ether is the intermediate of edible oil antioxidant BHA; Hydroquinone dimethyl ether is the intermediate of dyes, organic pigments and spices; Hydroquinone diethyl ether is the intermediate of photosensitive pigments and dyes.

4.airuike provide benzene diphenol is also used in the preparation of N,N’-diphenyl-p-phenylenediamine, which is an antioxidant and anti-odor agent for rubber and gasoline.

5.Photometric determination of phosphorus, magnesium, niobium, copper, silicon, arsenic. Polarographic and volumetric determination of iridium. Heteropolyacid reducing agent, copper, gold reducing agent.

5, in the field of water treatment, in the closed-circuit heating, cooling system of hot water and cooling water added hydroquinone, can inhibit the corrosion of water-side metals. Hydroquinone is used as a deoxidizer for boiler water, adding hydroquinone to the boiler water preheating and deoxidizing to remove the residual dissolved oxygen.
