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
