| Summary: | 4-Acyl-5-pyrazolone derivatives are known have characteristic as hard Lewis base. These ligands have a strong af?nity with hard Lewis acids like rare earth metals. In this experiment, two 4-Acyl-5-pyrazolone derivatives have been synthesised using Jensen methode, those are 4-sebacoylbys(1-phenyl-3-methyl-5-pyrazolone) (H2SbBP) and 4-adipoylbys(1-phenyl-3-methyl-5-pyrazolone) (H2AdBP). H2AdBP is yellow-brown colours powder mean while H2SbBP is a yellow colours powder. Characterisation of coumponds were established by measuring its melting point and Infra Red Spectra. The determination of melting point of H2AdBP and H2SbBP give 190.7oC-197,6oC and 132.9oC-135oC, respectively. The compounds have good solubility in chloroform. H2SbBP show a better performance than H2AdBP as ligand on the solvent extraction Y(III). The performance of ligands increase with increasing of pH and concentration. Extraction efficiency is studied with determining of the highest selectivity (a) of Ce(III) and Y(III), obtained when using H2AdBP as ligand with extraction condition pH 4.53. <br />
