Aliquat 336의 분배, 해리 평형 및 물질전달
The Distribution, Dissociation Equilibria and Mass Transfer of Aliquat 336
박상욱, 문진복, 박대원, 신정호
유기상(toluene, n-butyl acetate)과 전해질 수용액상(water, NaCl, NaOH, Na2S2O4)계에서 상이동 촉매인 tricaprymethyl ammonium chloride(Aliquat 336;Q+Cl-)의 분배계수와 해리평형상수를 25℃에서 측정하였다. 개량된 Lewis cell 을 사용하여 Q+Cl- 의 촉직계수를 측정하여 경막설을 보정한 Leveque 모델로부터 구한 이론값과 비교하였으며, 이로부터 toluene-물계와 toluene-NaOH 수용액계에서의 Q+Cl-의 순간 가역 해리반응을 수반한 물질전달속도를 정량적으로 설명할 수 있었다.
The distribution and dissociation equilibria of tricaprylmethyl ammonium chloride(Aliquat 336; Q+Cl-) were measured for the system of organic phase(toluene, n-butyl acetate)-aqueous phase(water, NaCl, NaOH, Na2S2O4). The enhancement factors of Q+Cl- were measured with a Lewis cell, and compared with those predicted from the theoretical model based on the film theory corrected by the Leveque model. the aqueous-phase mass transfer of Q+Cl- in the toluene-water system and toluene-NaOH aqueous solution system could be quantitatively explained as that with an instantaneous reversible dissociation reaction.
