Abstract
BURGOS, Ana E and SINISTERRA, Rubén D. PREPARATION AND CHARACTERIZATION OF COMPOUNDS OF ASSOCIATION BETWEEN RHODIUM(II) CARBOXYLATES (ACETATE, PROPIONATE AND BUTYRATE) AND ß-CYCLODEXTRLN. Rev.Colomb.Quim. [online]. 2010, vol.39, n.3, pp.427-445. ISSN 0120-2804.
This article describes the preparation and characterization of rhodium (II) acetate, propionate and butyrate, and their inclusion and/or association compounds with ß-cyclodextrin (ßCD). The characterization of the compounds in this study was performed by elemental analysis (CHN), FTIR spectroscopy, thermal analysis (TG/DTG/DSC), XRD powder pattern diffraction, 1Hand 13C nuclear magnetic resonance in solution 13C, and 31PCP/ MAS NMR in solid state. Besides, experiments for the determination oflongitudinal T1 relaxation times were also used. The results indicated the formation of inclusion or association compounds between rhodium (II) carboxylates (acetate, propionate or butyrate) and ß-cyclodextryn.
Keywords : rhodium (II) carboxylates; cyclodextrins; controlled release devices of drugs; inclusion compounds.
