The formation of reversed micelle of primary amine N1923 in different solvents is firstly investigated by determining the interfacial tension and electric conductivity in the organic phase and the IR spectra. A significant difference has been discovered for the formation of reversed micelle between the sulfate and the chloride.
The extraction of lactic acid(HA) with primary amine N1923(RNH 2) has been studied by means of a slope method and IR spectrophotometry at (298±1) K. The composition of the extracted complex was found to be RNH 2HA. The equilibrium constant of extraction was determined as lg K ex = 1 63. The results showed that lower temperature was favorable for the extraction.
