摘要:An amide/iminium zwitterion catalyst has a catalyst pocket size that promotes transesterification and dehydrative esterification. The amide/iminium zwitterions are easily prepared by reacting aziridines with aminopyridines. The reaction can be applied a wide variety of esterification processes including the large-scale synthesis of biodiesel. The amide/iminium zwitterions allow the avoidance of strongly basic or acidic condition and avoidance of metal contamination in the products. Reactions are carried out at ambient or only modestly elevated temperatures. The amide/iminium zwitterion catalyst is easily recycled and reactions proceed in high to quantitative yields.

摘要:The embodiments herein provide a method of synthesis for metallic nano-products such as metallic nano-antennas, metallic nano-rods, metallic nano-wires, metallic nano-prolate spheroids and metallic nano-oblate spheroids using saturated and unsaturated carboxylic acids. The method involves preparing a reaction mixture by mixing a polar protic solvent, a polar aprotic solvent or a non-polar solvent, a saturated fatty acid or an unsaturated fatty acid and a metallic salt. Then a mixture of reducing agents is prepared by mixing a polar protic solvent, a polar aprotic solvent or a non-polar solvent and a saturated fatty acid or an unsaturated fatty acid. The reaction mixture and the mixture of reducing agents are combined and heated solvo-thermally for a pre-determined period of time at a pre-determined temperature.
