The study on formation of the reversed micelle in extraction system of primary amine N1923 sulfate

The formation of reversed micelles in extraction systems of primary amine N1923 sulfate and its effect on the extraction mechanism have been investigated by the determination of the interfacial tension and the electrical conductivity in the organic phase. It has been proved by infrared spectroscopy and TEM imaging that the ammonium salt can form a reversed micelle or microemulsion. In addition, theoretical calculations are carried out in order to study further the microstructure of the reversed micelles. We are able to rationalize the unusual features of this extraction system that are found in our experiments. (C) 2002 Elsevier Science B.V. All rights reserved.
