Meanwhile, the methyl esters produced were analysed by using Gas Chromatography (GC) analy sis. The manipulative variables studied for this research are the oil/methanol molar ratio, types of catalyst and the weight of catalyst which were used to carry out the transesterification reaction. The optimal conditions for the oil/methanol molar ratio were found to be 1:48 (normal rice husk ash). The optimal condition for the amount of catalyst used was 30 wt. % which produced the yield of 75.2 % of methyl esters. 122 3rd ICYC 2010 Universiti Sains Malaysia 23rd-25th June 2010 ORAL PRESENTATION (INORGANIC) INO-O1 SYNTHESIS, CHARACTERIZATION AND BIOLOGICAL ACTIVITIES OF SOME INDOLE SCHIFF BASES AND THEIR METAL COMPLEXES 1 Mohamed Mustafa M, Hapipah MA, Mahmood Ameen A 1 2 2 Department of Chemistry, University Malaya, Kuala Lumpur Department of molecular medicine, Faculty of medicine, University Malaya, Kuala Lumpur E-mail: 1 Tryptamine Schiff bases were prepared by the condensation reaction of ethanolic solution of Tryptamine with Salicylaldehyde (TS), 5-Chlorosalicylaldehyde (TCS) and 5-Nitrosalicylaldehyde (TNS). The ligands were coordinated to Cu(II), Ni(II), and Zn(II) by the reaction of metal acetates with the corresponding ligand in a 1 : 2 metal to ligand ratio. The solid products formed was collected, washed with ethanol and recrystallized from DMF. All the ligands and complexes p repared have been 1 13 characterized by spectroscopic methods using IR, H, and C NMR, UV-Vis, and mass spectra. Elemental C H N analysis was carried out, and metal content was determined using atomic absorption spectroscopy. X-ray diffraction crystallography was done for the ligand 2-[2-(1H-indol-3-yl) ethyliminiomethyl]-4-nitrophenolate (TNS) and shows that it was exists in the zwitterionic f...
