Separating the Components of Panacetin: Introduction: Of the three components likely to be present in your sample of Panacetin (aspirin‚ acetanilide‚ and starch)‚ only starch is insoluble in the organic solvent dichloromethane (or methylene chloride)‚ CH2 Cl2. If a sample of Panacetin is dissolved as completely as possible in dichloromethane‚ the insoluble starch can be filtered out‚ leaving acetanilide and aspirin in solution. The purpose of this experiment is to extract the components of Panacetin

aspirin‚ and acetaminophen‚ but the third component in this experiment is unknown. The unknown component is suspected to be a chemical relative of acetaminophen‚ either acetanilide or phenacetin. Using techniques such as extraction‚ evaporation‚ and filtration‚ the three components will be isolated based on their solubilities and acid-base properties. The percent composition of Panacetin will also be deduced based on the masses of the three dried components; this is done to verify the composition attained
