peer agreement (net): +6| ватно-марлевая пробка cotton gauze plug (or cotton and gauze plug) Explanation: Hydroiodic Acid (Zeisel's Alkoxyl Method) Place about 0.1 g or 0.1 mL of the compound in a 16 × 150 mm test tube. Carefully add, by means of a pipet, 1 mL of glacial acetic acid and 1 mL of 57% hydroiodic acid (sp gr 1.7). Add a boiling chip, and insert into the mouth of the test tube a gauze plug as described below. The gauze plug is twisted so as to make a good fit and pushed down so that it is 4 cm from the mouth of the test tube. A small piece of nonabsorbent cotton is gently pushed on top of the plug by means of a glass rod so as to make a disk of cotton 2-3 mm thick. A piece of filter paper 2 × 10 cm is folded longitudinally, moistened with a solution of mercuric nitrate, and placed on the cotton disk. The test tube is immersed to a depth of 4-5 cm in an oil bath kept at 120-130°C. Do this reaction in the hood. When the reaction mixture boils, vapors rise through the porous plug, which usually turns gray. The volatile alkyl halide, rising through the plugs, reacts with the mercuric nitrate to produce a light orange or vermilion color due to the formation of the mercuric iodide. http://www.chemistry.ccsu.edu/glagovich/teaching/472/qualana... |
