渗透汽化分离膜及膜反应器　Ⅰ．聚离子复合腹性能的研究

Membranes for Pervaporation and Membrane Reactor Ⅰ.Studies on the Performance of Polyinonic Composite Membranes

通过两层复合制得壳聚糖－聚丙烯酸钠和壳聚糖－褐藻酸钠聚离子复合膜，研究了其对乙醇－水混合体系的分离性能，并比较了壳聚糖膜、聚丙烯酸钠、褐藻酸钠及聚离子复合膜对乙醇－水二元体系和乙酸－丁醇－乙酸丁酯－水多元体系的渗透汽化分离性能．结果表明，聚离子复合膜适于作膜反应器的膜材料．

The separation of water ethanol binary mixture through chitosan/poly(sodium acrylate)and chitosan/sodium alginate polvinonic composite membranes wasstudied using pervaporation process. The separation properties of chitosan membrane,poly (sodium acrylate),sodium alginate membrane and two PIC membranes on ethanolH2O and acetic acid-butanol-butyl acetate-H2O systems were compared, respecor,tively.The results indicated the PIC membranes can be used for the membrane reactor.
