Answer to Question #41825 in Inorganic Chemistry for Alan Alexander

Question #41825
Write a report based on the notes given below. 0.10g glycine and 0.4ml water taken in 5ml conical vessel. Warmed slightly to dissolve the glycine. 0.3ml acetic anhydride added and stirred about 5 minutes. Mixture cooled in the ice bath for 10 minutes. Precipitate collected by suction filtration and washed with a few ml of water. Crystals spread over a piece of filter paper or watch glass and air dried for 10 minutes. Glycine dissolved after 20 seconds when warmed in glycine water mixture. White needle-shaped crystals formed when reaction mixture cooled in ice. 0.14gm of solid obtained after filtration and drying of product. Mp of crystals recorded as 205-207. Solid product possible still slightly wet. Conclusion: Crystallized material was in fact acetamilide based on its melting point. Not highly pure. A second crystallization should produce a fairly pure material. But it would also decrease % recovery.
