1) Ketones are a family of organic compounds characterized by a carbonyl (carbon double bonded with an oxygen) bonded with two R groups (a carbon containing molecule). These compounds have great importance in pharmaceutical and chemical processes and as such, there is interest in characterizing their VLE behavior with the end goal of separating them. You are the thermodynamics specialist at the pharmaceutical plant, and have asked your technicians to collect the VLE data for two candidate ketones (Ketone 1 and Ketone 2) that your company is interested in (data attached). Of course, the two components do not obey Raoult's law, so you go back to your old undergraduate textbook in an effort to find an activity coefficient model. After looking through several models in the textbook, you finally select the Wilson Equation as your activity coefficient model. a) Find the two Wilson Equation parameters (112 and Azi). Explain all of the steps, but you may use Excel to perform the calculation (30 points) b) What is the vapor concentration of Ketone 1 assuming a liquid concentration of 0.5 at 1 atm and 400K? (30 points) Note that these two compounds, because of their complex nature, obey the Extended Antoine Equation (equation and parameters attached with the data)
