Panacetin Lab Write Up

Lab Report Format for Separating the Comp 1nts of Panacetin (2) and Recrystallization and run Point Measurement Identifying the Components of Panacetin (3). Lab Notebook entitle and Date Objective Explain the purpose of the experiment and how you plan to accomplish it. Technique Show the use of separatory funnel and evaporation of solvent setup Reaction(s) take the main reaction for the experiment and isolation lineation Physical Data List the molecular weight, melting leg, boiling point, density, solubility, and hazards of all pertinent chemicals used in the experiment.Data/Observations Your observations of the experiment, a. exercising weight of initial panacetin sample. b. Weight of sucrose collected. c. Weight of aspirin collected. d. Weight of unknown compound isolated e. Weight of recrystallized unknown compound f. Melting point range of recrystallized unknown compound. g. TLC sketches with appropriate data for Rf calculations (Clearly label each column of spots on the p age so I know what it is) h.
