Specifications

Hydroquinone, organic compound, white crystal. One 1 g, toxic, and adult can appear symptoms such as headache, dizziness, tinnitus, pale face. Flame, high combustible. Contact can react with strong oxidizer. The high thermal decomposition let out poisonous gases. Mainly used in making black and white contrast, anthraquinone dyes, azo dyes, rubber protective agent, stabilizer and antioxidant.
Flame, high combustible. Combustion is decomposed into carbon monoxide, carbon dioxide. Can react with strong oxidizer, the high thermal decomposition let out poisonous gases.
Flame burnable, reaction with oxidant, sodium hydroxide, smoke from burning stimulation. Is toxic, high toxic substances.
1. Hydroquinone is used primarily as a photographic developer. Hydroquinone and alkylate is widely used for monomer stored process of adding inhibitor, the concentration of the commonly used about 200 PPM. Hydroquinone is a methyl ether of edible oil antioxidants BHA intermediates; Hydroquinone dimethyl ether is the intermediate of dyes, organic pigments and spices; Hydroquinone diethyl ether is photosensitive pigment, dyestuff intermediates. Hydroquinone was used for preparing N, N '- diphenyl para-phenylene diamine, is used in rubber and gasoline antioxidants and deodorant. [2] 2. And gasoline used as rubber antioxidant, dye intermediates, etc. [2] 3. Processing field, the hydroquinone in closed circuit heating and cooling system of hot water and cooling water, the water side of metal corrosion effect. Hydroquinone in boiler water of deoxidizer, when the boiler water preheating oxygen adding hydroquinone, to remove residual dissolved oxygen.
