Colorless needle shaped crystals or white crystals. There is a special odor, and the extremely dilute solution has a sweet taste. Impurities turn light red or red under the action of light and air, and change color faster when exposed to alkali. Rate 11 54178. Flash point 79 44 ℃ (closed cup). 85 ℃ (open cup), self ignition point 715 ℃, combustion limit of vapor air mixture 1-7% to 8.6%. Flammable and highly corrosive. Toxic. 1g of phenol is dissolved in approximately 15mL of water (0.67%, can be dissolved in any ratio after heating at 25 ℃) and 12mL of benzene. Easily soluble in ethanol, ether, chloroform, glycerol, carbon disulfide, Vaseline, volatile oils, fixed oils, and strong alkaline aqueous solutions. Almost insoluble in petroleum ether. The pH value of the aqueous solution is about 6.0.

Used in the oilfield industry, it is also an important organic chemical raw material. It can be used to produce chemical products and intermediates such as phenolic resin, caprolactam, bisphenol A, salicylic acid, picric acid, pentachlorophenol, phenolphthalein, N-acetylethoxyaniline, etc. It has a wide range of applications in chemical raw materials, alkylphenols, synthetic fibers, plastics, synthetic rubber, pharmaceuticals, pesticides, fragrances, dyes, coatings, and oil refining industries.
