Supercritical fluid extraction of nylon 6: An investigation into the factors affecting the efficiency of extraction of caprolactam and its oligomers
Authors:Arnold Venema  Henk J. F. M. van de Ven  Frank David  Pat Sandra
Abstract:Caprolactam and oligomers can be efficiently extracted from nylon 6 by use of supercritical fluid extraction with carbon dioxide containing 7.5 % (m/m) methanol as the extraction fluid. The application of a static extraction, using an additional amount of methanol, is necessary to obtain high extraction efficiencies.
Keywords:SFE  Polymer  Monomer  Oligomer
