Question

Q4/in a two stage process, acetic acid (A)is extracted from water (W) into hexanol (H)
in a liquid-liquid extraction vessel and the extract is subsequently separated by distillation.
Assume that water is completely insoluble in hexanol. A mixture of 18wt% acetic acid and
the balance water is feed to liquid-liquid extraction vessel. Pure hexanol is feed to the
column to extracted the acetic acid. The water-rich stream leaving the vessel is 99.5wt%
water and the balance acetic acid. The hexanol-rich extract from the vessel is feed to a
distillation column. The composition of the distillate is 96wt% acetic acid and the balance
hexanol. The bottom stream contains 97.2wt% hexanol and recovers 95% of the hexanol
feed to the liquid-liquid extraction vessel. Calculate the percentage of acetic acid in the
process feed that is recovered in the distillate stream.

01:50 4G File Details 4CH003/UM1: Fundamentals of... Introduction NaBH4 OH C=0 H benzophenone diphenylmethanol Ketones are readily reduced to secondary alcohols by reaction with sodium borohydride. The aim of this experiment is to determine the time required to effect the complete conversion of the ketone, benzophenone to diphenylmethanol at room temperature. This investigation may be achieved by isolating and analyzing the reaction product after different reduction times. Infrared spectroscopy affords a convenient method of analysis; by comparing the IR spectrum of the crude reaction product at different time intervals one would expect to see the intensity of the hydroxyl absorption peak increase relative to that of the original carbonyl peak. From this you can deduce the optimum time for the reduction process at room temperature. Procedure Note the "reduction time" that the demonstrator assigns to your group. Different groups will be assigned different times, eithert = 2.5 minutes,…
