Product Description

Phenol is an organic compound with the chemical formula C6H5OH. It is a colorless needle-like crystal with a special smell. It's toxic. It is an important raw material for the production of certain resins, fungicides, preservatives and drugs (such as aspirin). It can also be used for disinfection of surgical instruments and excreta, skin sterilization, antipruritic and otitis media. The melting point is 43 ℃, slightly soluble in water at room temperature, and easily soluble in organic solvents; when the temperature is higher than 65 ℃, it can dissolve with water in any proportion. Phenol is corrosive and will denature local proteins after contact. When the solution touches the skin, it can be washed with alcohol. A small amount of phenol is exposed to the air, oxidized to quinone by oxygen, and is pink. When the ferric ion turns violet, this method is usually used to detect phenol.

Nature Description

Phenol is colorless acicular crystal or white crystal frit, combustible and strong corrosion. Toxic. The unpure product turns light red or red under the action of light and air, and changes color faster when exposed to alkali. It can be liquefied when mixed with about 8 water. Can absorb moisture in the air and liquefy. It has special odor and burning smell, and the extremely dilute solution has 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 315℃, vapor density 3.24, vapor pressure 0.13kPa (℃), combustion limit of vapor-air mixture 1.7-8.6. 1G phenol is dissolved in about 15ml of water (0.67,25 ℃ can be dissolved in any proportion after heating

Product Applications

Effect of phenol

1. Used in oil field industry, it is also an important organic chemical raw material, which can be used to prepare phenolic resin, self-lactamide, bisphenol A, salicylate, picric acid, pentachlorophenol, phenolphthalein, polyacetoethoxyaniline and other chemical products and intermediates are widely used in chemical raw materials, Alkylphenol, synthetic fibers, plastics, synthetic rubber, medicine, pesticides, spices, dyes, coatings, oil refining and other industries.
2. Used as analytical reagent, such as liquid chromatography solvent and organic modifier. Measure ammonia by Photometry and carbohydrate by thin layer method. It is also used as preservative, disinfectant and organic synthesis. It is widely used in plastic, dye, medicine, synthetic rubber, perfume, coating, oil refining, synthetic fiber and other industries.
3. As an antioxidant of fluoborate tin plating and tin alloy, it is also used as other electroplating additives.
4. Used to produce phenolic resin and bisphenol resin A, caprolactam, aniline, Alkylphenol, etc. In the oil refining industry, it is used as a refined lubricant selective extraction solvent, as well as the plastics and pharmaceutical industries.

Production method

Phenol was first recovered from coal tar, and at present most of them adopt synthetic methods. By the mid-60s of the 20th century, cumene method had been used to produce phenol. The technical route of acetone had developed to account for half of the world's phenol production, currently, phenol produced by this process has accounted for more than 90 of the world's phenol production. Other production processes include toluene chloride, chlorobenzene and sulfonation. There are two production methods in our country: cumene and sulfonation. As the sulfonation process consumes a large amount of sulfuric acid and caustic soda, only a few sulfonation process devices will be retained in our country, and cumene process will be the main production step by step. 1. The sulfonation method uses benzene as raw material, sulfonates with sulfuric acid to generate benzene sulfonic acid, neutralizes with sulfurous acid, and then uses caustic soda for alkali fusion, which is prepared through sulfonation, vacuum distillation and other steps. Raw material consumption quota: benzene 1004kg/t; Sulfuric acid (98)1284kg/t; Sodium sulfite 1622kg/t; Caustic soda (fold 100)1200kg/t. 2. Propylene and benzene in cumene process generate cumene under the action of aluminum trichloride catalyst. Cumene is oxidized to generate cumene hydroperoxide, and then decomposed with sulfuric acid or resin. Phenol and acetone are obtained at the same time. About 0.6t of acetone is co-produced per ton of phenol. Raw material consumption quota: benzene 1150kg/t; Propylene 600kg/t. 3. Chlorobenzene hydrolysis chlorobenzene catalyzes hydrolysis with caustic soda aqueous solution under high temperature and high pressure to generate sodium benzene, and then neutralizes it with acid to obtain phenol. 4. Crude phenol refining method is obtained by refining coal tar crude phenol. 5. In the presence of solid molybdenum catalyst, Laxi benzene conducts chlorine oxidation reaction at high temperature to generate chlorobenzene and water, and chlorobenzene is catalytically hydrolyzed to obtain phenol and hydrogen chloride, and hydrogen chloride is recycled.
