Phenol resin _ Wei Connaught Chemical (certified) _ phenol provided by Qingdao Jiaonan 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. Chemical properties of phenol: can absorb moisture in the air and liquefaction. Special smell, very dilute solution has a sweet taste. Corrosive. Chemical reaction ability. With aldehydes, ketones reacted phenolic resin, bisphenol A, and acetic anhydride; the reaction of salicylic acid phenyl acetate, salicylate. May also be halo, hydrogenation, oxidation, alkylation, carboxylation, esterification, etherification and other reactions. Phenol is solid at ordinary temperature, can not be successfully react with sodium, if the use of heating and melting phenol, was added sodium metal method experiment, phenol easily restored, at the time of heating and the impact test results of phenol color change. Some people take the following methods in the teaching experiment, simple operation, and achieved satisfactory results of the experiment. Join in a test tube 2-3 ml of anhydrous ether phenol medicine, take a piece of sodium metal bean size, with a dry filter paper surface kerosene, the price of phenol into the ether, you can see that sodium does not react with ether. Then a small amount of phenol added to the tube again shaken phenol, then sodium rapid response was observed in a test tube, a large amount of gas. The principle of this experiment is to phenol dissolved in ether phenol fungicides, the reaction of phenol with sodium to proceed smoothly edit phenol phenol resin (Phenol Formaldehyde, referred to as PF) resins, also known as bakelite, also known as wood flour. Original colorless or brown transparent material, marketing is often added colorants were red, yellow, black, green, brown, blue and other colors, granules, powder. Resistant to weak acids and bases, the case of acid decomposition, the case of alkali corrosion. Insoluble in water, soluble in acetone, alcohol and other organic solvents. Benzene derived phenolic condensation or a derivative thereof,
