Typical Properties

application

1.Mainly used as a photographic developer.

2.1,4-Dihydroxybenzene and its alkylate are widely used as polymerization inhibitors in monomer storage and transportation, and the concentration is usually about 200ppm.

3.1,4-Dihydroxybenzene monomethyl ether is an intermediate of edible oil antioxidant BHA; hydroquinone dimethyl ether is an intermediate of dyes, organic pigments and perfumes; hydroquinone diethyl ether is an intermediate of photosensitive pigments and dyes .

4.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 and arsenic. Polarographic and volumetric determination of iridium. Reducing agent of heteropoly acid, reducing agent of copper and gold.

5.In the field of water treatment, adding 1,4-Dihydroxybenzene 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. 1,4-Dihydroxybenzene is used as a deoxidizer for boiler water, and 1,4-Dihydroxybenzene is added to it when the boiler water is preheated and deoxygenated to remove residual dissolved oxygen.
