W/O 에멀션액막에서 이산화탄소와 AMP의 화학반응

Chemical Reaction of Carbon Dioxide with AMP in w/o Emulsion Membrane

멤브레인 = Membrane Journal v.14 no.4 , 2004년, pp.275 - 288  
초록

본 연구에서는 준 회분식 교반조를 사용하여 polybutene (PB)와 polyisobutylene (PIB)고분자를 용해한 벤젠 용액을 연속상, 물을 불연속상으로 구성한 w/o 에멀션액막에 $CO_2$을 흡수시켜 흡수속도를 측정하였다. 점탄성을 나타내는 Deborah 수를 사용하여 점탄성 비뉴튼액체에서 구한 부피물질전달계수 ($k_La$)를 고찰하고, 수용액에 첨가한 2-amino-2-methyl-1-propanol(AMP)와 $CO_2$의 반응 메카니즘을 해석하였다.

Abstract

Carbon dioxide was absorbed into water-in-oil (w/o) emulsion composed of aqueous 2-amino-2-methyl-1-propanol (AMP) droplets as a dispersed phase and benzene solutions of polybutene and polyisobutylene as a continuous phase in a flat-stirred vessel to investigate the effect of non-Newtonian rheological behavior on the rate of chemical absorption of $CO_2$, where the reaction between $CO_2$ and AMP in the aqueous phase was assumed to be a pseudo-first-order reaction. It was expressed that PIB with elastic property made the rate of chemical absorption of $CO_2$ accelerated by comparison of mass transfer coefficient of $CO_2$ in the non-Newtonian liquid with that in the Newtonian liquid.
