L1 And L2

Two imine derivative ligands, L1 and L2, have been synthesized using the microwave assisted organic synthesis (MAOS) method from the reaction between bibenzoyl and L-tryptophan and L-Histidine, respectively. The ligands were further transformed into two nickel(II) complex, C1 and C2, as the precursors of catalysts in glucose conversion to sorbitol. The two NiO/SiO2 catalysts, K1 and K2, have been generated through the calcination process of complex C1 and C2, respectively, which were previously impregnated into silica. The K1 catalyst with average particle size of 5 nm shows good catalytic activity, with no presence of any nickel leached into the solution, and has successfully converted 21.99% of glucose into sorbitol. The K2 catalyst with average particle size of 10 nm also shows good catalytic activity and has successfully converted 32.30% of glucose into sorbitol, although it shows the presence of leached nickel.

Physical And Chemical

Rare-earth phosphates are of particular interest because of their catalytic properties associated with the hydrolysis of many aromatic chlorides in the petroleum industry. Lanthanum phosphates (LaPO4) which have been doped with small amounts of copper have shown increased catalytic activity (1). However the physical and chemical characteristics of the samples leading to good catalytic activity are not known.Many catalysts are amorphous and thus do not easily lend themselves to methods of investigation which would include electron microscopy. However, the LaPO4, crystals are quite suitable samples for high resolution techniques.The samples used were obtained from William L. Kehl of Gulf Research and Development Company. The electron microscopy was carried out on a JEOL JEM-100B which had been modified for high resolution microscopy (2). Standard high resolution techniques were employed. Three different sample types were observed: 669A-1-5-7 (poor catalyst), H-L-2 (good catalyst) and 27-011 (good catalyst).
