Abstract

This study illustrated the results of pervaporation separation using crosslinked poly(vinyl alcohol) (PVA) with poly(styrene sulfonic acid-co-maleic acid) (PSSA-MA) for water-ethanol system at 25, 35, and $45^{\circ}C$. The contents of the crosslinking agents were 7, 9, and ll wt% against PVA and the feed compositions of 50, 20, 10 and 4.4% in water were investigated. Typical trends of permeability and separation factor in pervaporation were observed for both the crosslinking agents and operating temperatures. For water : ethanol = 10 : 90, and at $45^{\circ}C$, PSSA-MA 11 wt% membrane showed the permeability $58.92g/m^2{\cdot}hr$ and the separation factor 12003 respectively.

본 연구는 poly(vinyl alcohol) (PVA)와 가교제 poly(strene sulfonic acid-co-maleic acid) (PSSA-MA)을 이용하여 제조된 막을 물/에탄올 계에 대한 투과증발 실험을 25, 35 및 45$^{\circ}C$에서 수행하였다. 가교제의 함량은 7, 9, 11 wt.%를 사용하였으며, 원액의 조성은 무게비로 물 50, 20, 10 및 공비점인 4.4%에 대하여 조사하였다. 일반적인 투과증발 결과와 마찬가지로 가교제 함량의 증가 및 조업온도 증가에 따라 투과도 및 선택도에 대한 대표적 경향을 보여 주었다. 물 : 에탄올 = 10 : 90 조성에서 그리고 $45^{\circ}C$에서 선택도 12003와 투과도 $58.92g/m^2{\cdot}hr$를 PSSA-MA 11 wt%의 막이 보여 주었다.
