✦ Synopsis

The pervaporation separation of water-phenol mixtures was carried out using poly (vinyl alcohol) (PVA) cross-linked membranes with low molecular weight poly (acrylic acid) (PAA) at 30, 40, and 50°C. The separation was concentrated on the second stage of the water-selective process at which the phenol concentration could be 80 wt % of phenol. The high separation factor of a,,p, = 3580 for the PVA/PAA = 80/20 membrane was obtained for the phenol : water = 80 : 20 solution at 30°C. 0
