Surfactant Distribution in the Clouding of TX114

QIN Wei,HUANG Yan,DING Yuwen and DAI Youyuan State Key Laboratory of Chemical Engineering,Department of Chemical Engineering,Tsinghua University,Beijing 100084,China  
Distribution of TX114 between coacervate and aqueous phases in clouding of various initial TX114 concentrations was studied.Effects of temperature and salinity(Na2SO4)on the distribution of TX114 concentra- tion were also investigated.Differing from the nonionic surfactant C12E10,the distribution of TX114 is sensitive to the temperature,and it is observed that the TX114 concentration in the aqueous phase(Caq)does not depend on the initial TX114 concentration apparently at 45°C,and the Caq decreases with an increase of Na2SO4 concentration. Low initial TX114 concentration in unclouded solutions,high Na2SO4 concentration,and temperature are suggested to control the surfactant loss in large-scale cloud point extraction applications.
