You are designing a fermentation process that produces mixtures of water, acetone, ethanol, and 1-butanol. You are considering whether distillation will be an effective means of separating these compounds. As a first step, you have decided to determine the vapor pressures of each of the four compounds at each of the following temperatures:
T = 20, 50, 100, and 200°C. Thus, you are determining 16 vapor pressures-four for each of the four compounds.

A. Give your best estimate of each of the 16 vapor pressures, using only information contained in Appendices of this book.

B. Give your best estimate of each of the 16 vapor pressures, using the best research resources you have available to you.

C. Comment on your answers to parts A and B. How many of your answers were significantly different?
