Phenol (Phenol, C6H5OH) [1] is a colorless needle-like crystal with a distinctive odor. [2] It is toxic and is an important raw material in the production of certain resins, fungicides, preservatives, and medicines (such as aspirin). It can also be used to disinfect surgical instruments and dispose of excrement, [3] skin sterilization, itch relief and otitis media. Melting point 43℃, slightly soluble in water at room temperature, easily soluble in organic solvents; When the temperature is higher than 65 ° C, it can be miscible with water in any proportion. Phenol is corrosive and denatures local proteins upon contact. Its solution can be washed with alcohol when it touches the skin. Small amounts of phenol exposed to air are oxidized to quinone by oxygen and appear pink. This method is usually used to test phenol when ferric ions turn purple. ...

Main uses: Can separate a variety of organic raw materials, such as gasoline, benzene, kerosene, asphalt and so on. Naphtha is a light oil product obtained by distillation of crude oil or secondary processing of petroleum by cutting the corresponding fraction. Its boiling point range depends on the need, usually for a wide distillation range, such as 30-220℃. Naphtha is an important raw material for tube furnace cracking to produce ethylene and propylene and catalytic reforming to produce benzene, toluene and xylene. As a cracking raw material, it is required that the content of alkane and cycloalkane in the composition of naphtha is not less than 70% (volume); When used as catalytic reforming raw material for the production of high-octane gasoline groups, the feed is wide fractions, the boiling point range is generally 80-180 ° C, and when used for the production of aromatics, the feed is narrow fractions, the boiling point range is 60-165 ° C. ...
