fenolit

Fenolit, also known as phenol or carbolic acid, is an aromatic hydroxy compound with the formula C6H5OH. It is the simplest member of the phenol family and a foundational chemical in many industrial processes.

Physically, phenol is a colorless to pale yellow crystalline solid that emits a characteristic antiseptic odor. It melts at 40.5°C and boils at 181.7°C. It is moderately soluble in water and highly soluble in many organic solvents. As a weak acid, phenol can donate a proton to form phenoxide salts with bases.

Production and occurrence: Industrial phenol is mainly produced by the cumene process, in which benzene and propylene form cumene, which is oxidized to cumene hydroperoxide and cleaved to yield phenol and acetone. Phenol also occurs in small amounts in coal tar and is obtained as a byproduct in various refining operations.

Uses: Phenol is a building block for numerous materials, including phenol-formaldehyde resins (used in molded plastics and laminates), and bisphenol A, which is produced from phenol and acetone for polycarbonate manufacturing. It is a precursor to many industrial chemicals and finds use as an antiseptic in controlled applications and as a solvent and reagent in laboratories and manufacturing.

Safety and environment: Phenol is corrosive and toxic. It can cause burns on contact and, if absorbed through the skin, systemic toxicity. It evaporates in air and can irritate the respiratory tract. Handling requires protective equipment and proper engineering controls; environmental releases are regulated due to toxicity to aquatic life.
