Reaction in supercritical CO₂; an intercalation of 4-phenylazoaniline between layers of montmorillonite pillared with tetramethylammonium ions

Abstract

The intercalation reaction of 4-phenylazoaniline into montmorillonite pillared with tetramethylammonium ions has been performed successfully in supercritical CO₂ (SCC) at T = 313 K (P =15 MPa), demonstrating that SCC is a better medium than organic solutions for intercalating large amounts of guest molecules into a host compound without the contamination of solvent.
