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 α w/p , = 3580 for the PVA/PAA = 80/20 membrane was obtained for the phenol : water = 80 : 20 solution at 30°C. © 1994 John Wiley & Sons, Inc.
