The reactivity of a Lu2O3-promoted Rh/Al2O3 catalyst in the CO/H2 reaction is reported. Methane, heavier hydrocarbons, methanol, and ethanol are obtained. In situ DRIFTS has been employed to record the infrared spectra under the actual reaction conditions. The structure of the observed COads DRIFTS bands has been resolved into its components. The production of oxygenates (methanol and ethanol) has been correlated with the results of the deconvolution calculation. Specific sites for the production of methanol and ethanol in the CO/H2 reaction over a Rh,Lu2O3/Al2O3 catalyst are proposed.

The new mathematical model was developed by studying angle of slide using N, N-dimethyl acetamide, non-volatile liquid vehicle and prepared liquisolid tablets, in which the different concentrations of non-volatile liquid adsorbed over carrier and coating material separately. Both DSC and FT-IR study showed better compatibility and stability. The optimized formulation showed higher drug release during in-vitro and in-vivo study against conventional and marketed preparation. The present work concludes that N, N-dimethyl acetamide enhanced the solubility of pioglitazone HCl with higher dissolution rate through liquisolid technique.
