Preparation of Prevaporation Membranes for Separation of Water-Ethanol Mixture

강용수, 박현채

초록

가교된 poly(vinyl alcohol) (PVA) 막에 의한 물-에탄올 흔합물의 투과증발실험을 수행하였다. 물에 대한 선택투과성을 높이기 위하여 단순 가교 PVA막의 한쪽 표면을 monochloroacetic acid나 propane sultone과 반응시켜 표면이 물에 대한 친화력이 높도록 하였다. 그 결과 monochloroacetic acid로 개질된 막 (나트륨염형)의 성능은 표면 개질되지 않은 막에 비하여 투과도 및 선택투과도가 각각 2배 및 4배 이상 증가하였다. 그러나 propane sultone으로 개질된 막의 성능은 기대와는 달리 크게 변하지 않았다.

Pervaporation of water-ethanol mixture through crosslinked poly(vinyl alcohol) (PVA) membranes was performed. In order to enhance the permselectivity of water, one side of the crosslinked PVA membrane was hydrophilically modified by reacting either monochloroacetic acid or propane sultone. The membrane (sodium carboxylate form) modified by monochloroacetic acid exhibited that the flux and permselectivity increase more than two and four times, respectively, compared to those of the simply crosslinked PVA membrane. However, the membrane modified by propane sultone showed that the transport properties remain almost unchanged.
