VARUN VEIGAS 10/16/2008 34269580 MIKE BOVINO EXPERIMENT 2 I. Introduction A. Extraction and Evaporation: Separating the Components of “Panacetin.” The purpose of the experiment was to separate Panacetin into its components to use their solubilities and acid-base properties. Panacetin contains aspirin, sucrose and an unknown component that may be either acetanilide or phenacetin. B. The diethyl ether (C 2 H 5 OC 2 H 5 ) dissolved the aspirin (C 6 H 4 (OCOCH 3 )COOH) and the unknown to leave the sucrose (C 12 H 22 O 11 ) solid behind. The sodium hydroxide (NaOH) converted the aspirin (C 6 H 4 (OCOCH 3 )COOH) into sodium acetylsalicylate. Hydrochloric acid (HCl) was used to precipitate the aspirin (C 6 H 4 (OCOCH 3 )COOH) from the aqueous layer. II. Procedure/Results A. TO SEPARATE SUCROSE -0.400g of Panacetin were weighed and transferred to a tared 15-mL screw-cap centrifuge tube. 8.0mL of diethyl ether were added to the centrifuge tube. The solid was dissolved in the solvent by shaking the tube.
