Phenol cleaners, Wei Connaught Chemical (certified), phenol roughness provided by Qingdao Wei Connaught Chemical Co. Qingdao Wei Connaught Chemical Co. (www.qdweinuo.com) is specialized in the "phenol, aniline, ethylene, n-butanol, isobutanol, n-propanol, isopropanol, methanol," the business, the company adhering to the "integrity management, service intentions, "the idea, to provide you with the highest quality products and services. Welcome to inquire! Contact: Feng Zhongying. Qingdao phenol phenol chemical properties; you can test with ferric chloride solution of phenol, after adding ferric chloride solution was observed to turn purple. Reaction of phenol with concentrated bromine tribromophenol white precipitate, but does not react with dilute bromine water. Conjugation: with a phenol hydroxyl oxygen lone pair of electrons on the p-orbital conjugation with the benzene ring may be large π bond, a total of 8 π electrons phenol with saturated bromine water reaction to produce white 2,4,6-tribromophenol precipitation. The reaction is commonly used in qualitative and quantitative detection of phenol. Phenol has weak acid (25 ℃, Ka-10) phenol detergent, alkali and generate salts. Most of its salts are water soluble, can be carbonated (Ka-7) are free, take advantage of this feature can distinguish between phenols and carboxylic acid, phenol, phenol is used to separate from the industrial complex of coal tar. Phenol and role aqueous or alcoholic solution of ferric chloride. How to edit phenol foam is a phenolic foam from a phenolic resin foam obtained by foaming. Early dominant market share and polystyrene foam, compared to PVC foams, polyurethane foam and other materials in ways it has a special flame retardant excellent performance. Its light weight, rigidity phenol prices, good dimensional stability, chemical resistance phenol preservative, heat resistance, flame retardant, self-extinguishing, low smoke, flame penetration-resistant, fire-free spilled material, low prices, is electrical, instrumentation, construction, petrochemical and other industries ideal insulation thermal insulation materials, and thus subject to widespread attention. Phenolic foam foam has become one of the fastest growing varieties. Consumption is growing, expanding range of applications, research and development at home and abroad are quite active. However, the biggest weakness of phenolic foam is brittle, opening rate, thereby increasing its toughness is a key technology to improve the performance of phenolic foam.
