Detailed Product Description: | Chemical properties editor 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 phenol factory direct, 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 dissolved in ether phenol phenol market prices, the reaction of phenol with sodium smoothly. 1. Verify that the acidic phenol take 2mL phenol solution in a test tube, dropping litmus reagent, observable phenomena. 2. In the three tubes were taken a small amount of solid phenol, and thereto were added 2-3 ml of sodium hydroxide solution, 2-3mL sodium carbonate solution, 2-3mL sodium bicarbonate solution, phenol is thoroughly shaken, the phenomenon observed and compared (Note that the tube salt solution for bubbles.) 3. of 2mL sodium hydroxide solution in a test tube, 2-3 drops of phenolphthalein test solution was added dropwise phenol offer, then add a small amount of solid phenol, observe the color change. 1. exchange phenomenon can not make litmus phenol red. 2. Solid phenol soluble in sodium hydroxide solution and sodium carbonate solution, no bubbles; insoluble in sodium bicarbonate solution. 3. make phenol red solution (drops of phenolphthalein test solution of sodium hydroxide solution) faded.
