Detailed Product Description: | Chemical properties: can absorb moisture in the air and liquefaction. Chemical Reagent home with special smell, very dilute solution has a sweet taste. Corrosive. Chemical reaction ability. With aldehydes, ketones reacted phenolic resin, bisphenol A chemical reagent, 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 chemical reagents sodium instrument, if heating and melting phenol, was added sodium metal method, the experiment alkanes chemical reagents, phenol susceptible to reduction, the color change of phenol and when heated affect experimental results. Some people take the following methods in the teaching experiment, simple operation, and achieved satisfactory results of the experiment. Was added in a test tube, 2-3 mL of anhydrous diethyl ether, take a piece of sodium metal bean size, the surface of the dry filter paper with kerosene, into diethyl ether, sodium can be seen does not react with diethyl ether. Then a small amount of phenol added to the tube again shaken, then observed sodium rapid reaction in a test tube, a large amount of gas. The principle of this experiment is to phenol dissolved in ether, the reaction of phenol with sodium to proceed smoothly. Product Code: 31410234016 Product Name: Activated carbon Specifications: 1 Notes: 1 Product Category :( a) the main raw material chemicals can be almost all carbon-rich organic materials, such as coal, wood, shell, coconut, walnut shells, almond shells, shells and other dates. These activated carbonaceous material in an oven, at a high temperature and a certain pressure is converted to charcoal by pyrolysis. In this activation process, the large surface area and pore structure gradually formed complex, the so-called adsorption process is in these pores and on the surface of the activated carbon in the pore size of the adsorbate has the role of selective adsorption, which is macromolecules can not enter due to the reason charcoal picture than its smaller pores within the activated carbon pore (9) Activated carbon is dominated by carbon-bearing material as raw material, the high temperature carbonization and activation obtained hydrophobic adsorbent. Chemical Reagent home _ Jing Chi Bose equipment (certified) _ chemicals by Dongguan Changan Jing Chi Bose equipment operators offer. Dongguan Changan Jing Chi Bose equipment operators (www.jingchb.com) is an industry leader in Dongguan, Guangdong, chemical reagents, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
