Wei Connaught chemical factory in Shandong phenol, phenol production technology, provided by Wei Connaught chemical phenol. We are Qingdao Wei Connaught Chemical Co. (www.qdweinuo.com) at: Qingdao, Shandong specialized in: phenol, aniline, ethylene, n-butanol, isobutanol, n-propanol, isopropanol, methanol, phenol, phenol Qingdao chemical properties; solution of ferric chloride can be tested phenol, ferric chloride was added to the solution turned purple was observed. Bromine reacts with concentrated phenol Tribromophenol white precipitate, but does not react with dilute bromine. Conjugate effects: with a phenol hydroxyl oxygen lone pair of electrons on the p-orbital and the benzene ring may be large π-conjugated bond, a total of 8 π electrons react a phenol with a saturated bromine water to produce white 2,4,6-tribromophenol precipitation. The reaction is commonly used in qualitative and quantitative detection of phenol. There are slightly acidic phenol (25 ℃ phenol market, Ka-10), to form salts with alkali effect. Most of its water-soluble salts thereof, can be carbonate (Ka-7) of the free phenol, the use of this feature can be distinguished phenols and carboxylic acids, for separating phenol from industrial complex coal tar. And the role of phenol aqueous or alcoholic solution of ferric chloride. Phenol was first recovered from coal tar phenol production technology, currently mostly synthetic methods. By the mid-1960s, began to use cumene production of phenol, acetone technology roadmap how much money a ton of phenol, phenol has developed half of the world production, is currently using this process to produce phenol accounted for 90% of the world production of phenol the above. Other production processes include toluene chloride, chlorobenzene France, sulfonated France. There are two methods of cumene and sulfonated production methods. Due to consume large amounts of sulfuric acid and sulfonated law caustic soda, our country will retain only a small number of sulfonated law means, and gradually to cumene production based.
