ORGANIC CHEMISTRY LANEY COLLEGE CHEM 12A Version 3.0, 2/8/07 Simple and Fractional Distillation. Reading Experiment 5 in Pavia and the Required Reading for this experiment Prelab Make the usual entries in your notebook (Name, Title, Date, Purpose, and Outline), plus draw a picture of each apparatus that you will use (simple and fractional distillation setup). Your diagram does not have to be a piece of artwork. It simply needs to show the assembled apparatus used in each type of distillation with labels for all of the parts (see example in the lab lecture). Prepare two tables in your notebook for recording the volume and temperature data for each part. An example of the correct apparatus will also be on display in the laboratory. Choose a partner since you will be working in pairs for this experiment. Note that you will work together with your partner to perform first the simple distillation and then perform the fractional distillation

Unformatted text preview: on the same unknown mixture . Procedure Follow the procedure given in the text. You will save samples during your experiment that will be analyzed by Gas Chromatography (GC) during the following week. To Complete the Experiment On the same graph, plot the temperature of the distillate (y-axis) as a function of the total volume of collected distillate (x-axis) for both the simple and fractional distillations as described in the ANALYSIS section of the experiment. Connect the data points for each type of distillation (don't try to find a straight line). From your graph determine what the components of your mixture that you started with. You will be able to confirm your results in the following week during the GC experiment. In your conclusion be sure to comment on the observed differences between simple and fractional distillation....
