Phenol is an important raw material for the production of pesticides, and can be used to produce insecticides such as carbofuran, cypermethrin, and vegetable phosphorus, fungicides such as prochloraz, triadimefon, and difenoconazole, herbicides 2,4-D, 2,4-D butyl, and rodenticides such as chlorfenapyr and bromochlorpyrifos. In addition, phenol is alkylated to form alkylphenols, such as nonylphenol, dinonylphenol, and sec-octylphenol, as well as polyaromatic phenols, such as 2-methylbenzylphenol and 2,2-dimethylbenzylphenol, which are all important intermediates for surfactants.

Phenol is 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, 2,4-D, adipic acid, phenolphthalein N-acetylethoxyaniline, etc. It has important uses in chemical raw materials, alkylphenols, synthetic fibers, plastics, synthetic rubber, medicine, pesticides, spices, dyes, coatings and oil refining industries. In addition, phenol can also be used as a solvent, experimental reagent and disinfectant. From 1997 to 2002, the demand for phenol in major regions such as the United States, Western Europe and Japan maintained an average annual growth rate of 4.2%.
Phenol is a colorless needle-shaped crystal or a white crystalline melt, which is flammable and highly corrosive. Toxic. Impure products turn light red or red under the action of light and air, and change color faster when encountering alkali. It can be liquefied when mixed with about 8 water. It can absorb moisture in the air and liquefy. It has a special odor and burning smell, and the extremely dilute solution has a sweet taste. Relative density 1.0576, freezing point 41℃, melting point 43℃, boiling point 181.7℃ (182℃), refractive index 1.54178, flash point 79.44℃ (closed cup), 85℃ (open cup), autoignition point 715℃, vapor density 3.24, vapor pressure 0.13kPa (40.1℃), vapor and air mixture combustion limit 1.7-8.6. 1g phenol is soluble in about 15ml water (0.67, can be dissolved in any proportion after heating at 25℃) and 12ml benzene. It is easily soluble in ethanol, ether, chloroform, glycerol, carbon disulfide, vaseline, volatile oil, fixed oil, strong alkali aqueous solution. It is almost insoluble in petroleum ether. The pH value of the aqueous solution is about 6.0.
