Phenol is colorless acicular crystal or white crystalline frit, flammable and corrosive. Toxic. Impure products become light red or red under the action of light and air, and change color faster in case of alkali. It can be liquefied when mixed with about 8 water. Absorbs moisture from the air and liquefies. It has a special odor and burning smell, and a very thin solution has a sweet taste. Relative density 1.0576, freezing point 41 ° C, melting point 43 ° C, boiling point 181.7 ° C (182 ° C), refractive index 1.54178, flash point 79.44 ° C (closed cup), 85 ° C (open cup), spontaneous combustion point 715 ° C, vapor density 3.24, vapor pressure 0.13kPa (40.1 ° C). The combustion limit of the mixture of steam and air is 1.7-8.6. 1g phenol is dissolved in about 15ml water (0.67, can be dissolved in any proportion after heating at 25ºC) and 12ml benzene. Soluble in ethanol, ether, chloroform, glycerin, carbon disulfide, petroleum jelly, volatile oil, fixed oil, strong alkali aqueous solution. Almost insoluble in petroleum ethers. The pH of the aqueous solution is about 6.0.
