✦ Synopsis

Liquid extractions of benzoic acid-toluene solutions by means of water were studied under varying flow rates of both solvents in a 2-in. perforated-plate column to which pulsations of different frequencies and amplitudes were applied. Studies on reversal of the phase of the dispersion were made. With fixed flow rates of both solvents, the rate of extraction increased much more rapidly when the flow through the perforation became turbulent. The results are correlated by means of Reynolds number based on the flow through the perforations and are calculated from the product of the frequency and amplitude EQUIPMENT AND MATERIALS diagram Of the extraction unit consisting Of perforated-plate separators, rotameter, ' Ow controlst pumps, tanks, and Other W.
