Resorcinol

Resorcinol (or resorcin) is a benzenediol (m-dihydroxybenzene), a type of phenol, that is used in various pharmaceutical and industrial applications. It is a white, crystalline solid that is soluble in water, alcohol, and ether.

Chemical properties

Resorcinol has the chemical formula C6H4(OH)2. It is one of three isomeric benzenediols, the others being hydroquinone and pyrocatechol. Resorcinol has a slight phenolic odor and sweetish taste.

Production

Resorcinol is produced in large quantities by sulfonating benzene with fuming sulfuric acid and fusing the resulting benzenedisulfonic acid with caustic soda. Other methods of production include the diazotization of para-aminophenol, the decomposition of para-aminoazobenzene with potassium hydroxide, and the oxidation of quinone with hydrogen peroxide.

Uses

Resorcinol is used in the production of resins and in the chemical synthesis of pharmaceuticals. It is also used in the preparation of dyes, plastics, and rubber. In medicine, resorcinol is used as an antiseptic and disinfectant, and in the treatment of various skin diseases.

Health effects

Exposure to resorcinol can cause irritation to the skin, eyes, and respiratory tract. Ingestion can lead to symptoms such as nausea, vomiting, and convulsions. Long-term exposure can result in kidney and liver damage.
