R. Ishii et al., REACTION IN SUPERCRITICAL CO2 - AN INTERCALATION OF 4-PHENYLAZOANILINE BETWEEN LAYERS OF MONTMORILLONITE PILLARED WITH TETRAMETHYLAMMONIUM IONS, Chemical communications, (16), 1998, pp. 1705-1706
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 t
hat SCC is a better medium than organic solutions for intercalating la
rge amounts of guest molecules into a host compound without the contam
ination of solvent.
