The pervaporation separation and the swelling behavior of acetic acid-water mixtures were investigated at 30, 40, and 50ΠC using the crosslinked poly(vinyl alcohol) (PVA) membranes with varying the poly(acrylic acid) (PAA) contents and the acetic acid concentration in the feed mixture. Typically, fo
Crosslinked blended membranes of poly(vinyl alcohol) (PVA) and N-methylol nylon-6 were prepared either by thermal crosslinking at 180Β°C or by chemical crosslinking with maleic acid. The pervaporation performance for the separation of ethanol-water mixtures of these membranes was investigated in term
