Description
Hydroquinone, also known as hydroquinone, is a white or light gray crystalline solid at room temperature and pressure. The molecular structure consists of a benzene ring and two opposing hydroxyl groups, and this symmetrical structure is the basis of chemical activity.
Flammable, soluble in hot water, ether, and ethanol, slightly soluble in benzene. Reductive, it undergoes mild oxidation to obtain brown p-benzoquinone, which is then reduced to obtain Hydroquinone. The benzoquinone hydroquinone redox pair exists in many biomolecules, such as coenzyme Q.
The phenolic hydroxyl hydrogen of Hydroquinone has weak acidity and can lose one or two protons to generate the corresponding phenolic anion. Mainly used as a reducing agent, developer, monomer inhibitor, and skin whitening agent. Hydroquinone ether is a raw material used in the production of dyes and fragrances.
Physical properties: Hydroquinone has a melting point of 172-175 ° C and a boiling point of approximately 287 ° C. It has moderate solubility in water, especially in hot water, and is also easily soluble in organic solvents such as ethanol, ether, and acetone.
Chemical properties: The core chemical characteristic of Hydroquinone is its reducibility. It can be easily oxidized to the corresponding quinone – benzoquinone. This reversible oxidation-reduction reaction is the basis for most of its applications, whether as an electron donor in photographic development or as a free radical terminator in the polymer industry.
