Distillation of a Liquid Mixture

Procedure

For this experiment you will work in two-person teams as follows. Choose a partner and write their name in your lab notebook. Obtain about 44 mL of a whiskey sample and split it 50:50 with your partner so that each of you has about 22 mL of sample. Write the name of the whiskey sample in your lab notebook.

During week 1, you and your partner will perform independent simple distillations of your respective 22 mL samples. Then you will recombine your samples and, working together, perform a fractional distillation on the 44 mL sample. Each of you will keep one compound from the fractional distillation. During week 2, you will measure the FT-IR spectrum of the compound you kept and determine its odor. When the lab is complete, you will exchange T vs. V data for your simple distillations, as well as FT-IR spectra, so that each of you has a complete set of data on all distillations and both compounds. Each of you will be responsible for writing up your own lab report.
