Question: In a distil Jation process 550 lbm/h of a benzene, toluene, and water mixture is fed to the distiller. This feed contains 2.0(101 )% toluene. The distilled product is 93% benzene and 7.0% water. The waste contains 35% water and 1.0(101)% benzene. Determine the rate of production of the distilled product and the percentages of benzene and water in the feed.
Imagine that a chemist has cyclohexanone, triphenylphosphine, butyllithium, and 2-bromobutane. Draw the organic product resulting from using these chemicals in the Wittig reaction.
Calculate the equilibrium constant, K. (e) Which side of the reaction (reactants or products or neither) is favored structurally?
