TFEMA(2,2,2-trifluoroethylmethacrylate)는 광섬유 코팅제, 발수 발유제, 기능성 페인트, 방오가공제, 고분자의 표면개질제 등의 많은 응용제품에 활용되는 단량체로 그 시장규모가 국내에서 600억원, 전 세계에서 8,000억에 해당하는 고부가가치의 화학원료이다. TFEMA는 현재 산촉매하의 8.$0^{\circ}C$의 고온에서 TFEA(2,2,2-trifluoroethaol)와 MA(methacrylic acid)와의 에스텔화 반응으로 제조된다.(중략)

Trifluoroethyl methacrylate (TFEMA) is used in the preparation of water-repellant paints and optical fiber clading materials, and is manufactured by esterification reaction of trifluoroethanol (TFEA) and methacrylic acid (MA). To estimate the applicability of a pervaporation membrane for the esterification TFEMA esterification, the basic pervaporation properties for TFEA/water mixture were determined using a commercial poly(vinyl alcohol) membrane (GFT Membrane $Pervap^{\circledR}1005$). The effect of TFEA concentration in feed solution and operating temperature on the pervaporation properties was determined. The total permeation flux decreased with increasing TFEA concentration from 90 to 99 wt%, but the separation factor of TFEA/water showed maximum values at 95 wt% TFEA concentration. With increasing feed temperatures from 50 to 8$0^{\circ}C$, the permeation flux and separation factor increased. Higher separation factors and permeation fluxes were observed at 8$0^{\circ}C$ of feed temperature. This pervaporation performance confirmed that the commercial pervaporation membrane could be successfully applied to esterification of TFEMA.
