Rate study of reduction of 2-heptanone with samarium iodide by gas chromatography.
This article describes a newly developed method of gas chromatography (GC) for the rate study of the reduction of organic compounds by samarium iodide. Solvent extraction was used to reduce the interference of GC analysis by inorganic species. Adequate recoveries ranged from 88.3 to 94.5 % and good linearity ranging from 0.1 to 2.1 mM was determined. An internal standard, decane, was used to enhance the precision of this test. The coefficient variations of intra-day and inter-day ranged from 0.22 to 3.00%. The stability of the reacted sample was also assessed. In addition, the reaction rates of the reduction of 2-heptanone by samarium iodide in the presence of hexamethylphosphoramide were examined. The results presented hererin demonstrate the utility of this method in kinetic studies.
