Application field
|
1. Hydroquinone is mainly used as a photographic developer. Hydroquinone and its alkyl compounds are widely used as inhibitors
added during monomer storage and transportation, and the commonly used concentration is about 200 ppm. To 2. Used as antioxidant for rubber and gasoline, etc. 3. In the processing field, adding hydroquinone to the hot water and cooling water of the closed-circuit heating and cooling system can inhibit corrosion of the metal on the water side. Hydroquinone is used as an oxygen scavenger for boiler water. When the boiler water is preheated to remove oxygen, hydroquinone is added to it to remove residual dissolved oxygen. To 4. It is to manufacture anthraquinone dyes, azo dyes, and pharmaceutical raw materials. To 5. Used as corrosion inhibitor, stabilizer and antioxidant of detergent, and also used as hair dye in cosmetics. 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. |
