The difference between coked phenol and phenol_Kain Industrial Additive

Coking phenol and phenol are both important chemical raw materials and are widely used in chemical production and organic synthesis. They also belong to the same class of substances. So what is the difference between them?

Introduction to coked phenol

Coked phenol is White crystals, which gradually turn into reddish crystals in the air, with a special smell. Toxic, the maximum allowable concentration in the air is 5mg/m3. Boiling point 181.90, melting point 40.6 degrees. It is an organic toxic corrosive. Extraction method: Coal tar is fractionated, and the phenolic component segments are cut out and further distilled and purified. Distillation temperature and color control are key to grade control.

Introduction to phenol

Phenol, also known as carbolic acid, is a colorless needle-like crystal or white crystalline frit that easily turns pink when exposed to air or light. Relative density (20℃/4℃) 1.0576, freezing point 41℃, melting point 43℃, boiling point 181.7℃, flash point 78℃, fire point 715℃, refractive index (n41D) 1.5425. Easily soluble in ethanol, ether, chloroform, glycerin, carbon disulfide, Vaseline, volatile oil, and strong alkali aqueous solution. Slightly soluble in water at room temperature, miscible with water above 65°C, and insoluble in petroleum ether. It has a special smell, is highly corrosive, and is toxic.

The difference between coked phenol and phenol

Coked phenol is Important chemical raw materials extracted from coal tar are mainly used to produce phenolic resin, caprolactam, bisphenol A, adipic acid, aniline, alkylphenol, salicylic acid, etc. In addition, it can also be used as solvents, reagents, disinfectants, etc. , widely used in synthetic fibers, synthetic resins and spices.

Phenol is an important organic chemical raw material. It can be used to produce phenolic resin, caprolactam, bisphenol A, salicylic acid, picric acid, pentachlorophenol, 2,4-D, adipic acid, phenolphthalein n-acetyl Chemical products and intermediates such as ethoxyaniline have important uses in industries such as chemical raw materials, alkylphenols, synthetic fibers, plastics, synthetic rubber, medicines, pesticides, spices, dyes, coatings and oil refining. In addition, phenol can also be used as a solvent, experimental reagent and disinfectant. The aqueous solution of phenol can separate the proteins and DNA on the chromosomes in plant cells, making it easier to stain the DNA.

From the above introduction, do you understand the difference between coked phenol and phenol?
