Organic Intermediate CAS 108-95-2 Phenol
Phenol is an important organic synthesis of raw materials for the preparation of phenolic resin, bisphenol A, phenolphthalein, picric acid, salicylic acid, alkyl phenol and other chemicals, can also be used as a solvent. Widely used in the manufacture of phenolic resin, epoxy resin, nylon fiber, plasticizers, developers, preservatives, pesticides, fungicides, dyes, pharmaceuticals, spices and explosives. For the oil industry, is also an important organic chemical raw materials, it can be used to prepare phenolic resin, caprolactam, bisphenol A, salicylic acid, picric acid, pentachlorophenol, phenolphthalein, N-acetoethoxy aniline and other chemical products Intermediates, in the chemical raw materials, alkyl phenols, synthetic fibers, plastics, synthetic rubber, pharmaceuticals, pesticides, spices, dyes, coatings and oil refining and other industries have a wide range of applications. Used as analytical reagents, such as liquid chromatography for the solvent and organic modifier, photometric determination of ammonia, thin-layer determination of carbohydrate reagents. Also used as preservatives, disinfectants, and for organic synthesis. Widely used in plastics, dyes, pharmaceuticals, synthetic rubber, spices, coatings, oil refining, synthetic fiber and other industries. Antioxidants for fluoroborate tin and tin alloys are also used as other plating additives. For the production of phenolic resin, bisphenol A, caprolactam, aniline, alkyl phenol and so on. In the oil refining industry as a refined oil selective solvent extraction, but also for the plastics and pharmaceutical industry.
1. Sulfonated alkali melting method: the old industrial production method of phenol is sulfonated alkali melting method, with concentrated sulfuric acid or sulfur trioxide as a sulfonating agent, so that the sulfonation of benzene and sulfonic acid into benzene sulfonic acid, and then with sodium sulfite And then let the sodium benzenesulfonate react with the caustic soda in the molten state to produce sodium phenol and Na2SO3 dissolved in water, which is separated by crystallization, and the crude solution of the phenol sodium after impregnation is acidified with sulfur dioxide or dilute sulfuric acid to obtain crude product. Pressure distillation derived products.
2. Propylene: propylene separated from the cracked gas in the presence of aluminum trichloride catalyst, at 80 ~ 90 ℃ atmospheric pressure and benzene for the alkylation reaction, distillation separation of cumene, cumene With air at 100 ~ 120 ℃ and 300 ~ 40
0 kPa pressure directly oxidized to hydrogen peroxide cumene, the concentration of about 80% of the oxidation solution, hydrogen peroxide cumene with sulfuric acid at 60 ° C under normal pressure cracking into phenol and acetone, and finally refined by acetone and phenol The The method is low cost and less waste, raw materials from petroleum and propylene and petroleum benzene, and can be obtained phenol and acetone, these two products are widely used chemical raw materials. The intermediate product hydrogen peroxide cumene can be separated as a rubber industry initiator, the intermediate cumene can be used as a raw material for the production of herbicidal isoproturon intermediates to isopropylaniline. This method is suitable for large-scale continuous production, the world’s most of the production of phenol using the method
