Question
In the Keyes process for making absolute alcohol from alcohol containing 5% by wt. of
water, a third component benzene is added to the alcohol feed. Benzene lowers the
volatility of alcohol and takes the entire water impurity overhead as constant boiling
mixture of composition 18.5% alcohol, 7.5% water and 74% benzene. The residue from the still is absolute alcohol.
Compute:
• the amount of benzene
• Impure alcohol required for the production of 2,500 kg absolute a
