SOLVOTHERMAL SYNTHESIS AND CHARACTERIZATION OF TEREPHTHALIC ACID-BASED METAL-ORGANIC FRAMEWORKS AND THEIR CATALYTIC APPLICATION IN BIODIESEL PRODUCTION

Metal-Organic Frameworks (MOFs) are a class of porous crystalline materials, consisting metal ions or nodes linked with organic ligands. The study was aimed at solvothermal synthesis and characterization terephthalic acid-based their catalytic application in biodiesel production. Three MOFs Cu-, Fe-, Cr-based were solvothermally synthesized, characterized applied as catalysts production using ethanol oil extracted from Yellow Oleander seeds. synthesized acid the linker copper (II), iron (III) chromium nitrates ion sources. Each showed high melting point exceeding 360 oC. Microscopic view powder X- ray diffraction analysis indicated Cu-MOF to be numerous sharp peaks while those for Fe- Cr-MOFs amorphous. A comparison FT-IR spectra ligand confirmed presence MOFs. In absence catalyst, transesterification not achieved. However, more catalyst resulted yield (83.33%) shorter time compared less (33.33%) Cr- (25.00%) Thus, ability order: > Fe-MOF Cr-MOF. Hence especially Cu-MOFs can Further studies (single X-ray diffraction) should done proper elucidation crystal structure MOFs.
