SYNTHESIS AND CHARACTERISATION OF β-DIKETONES
摘要
Abstract
A process for the preparation of β-diketones,especialy aromatic β-diketones,by Claisen condensation reaction of acetophenone or its derivatives with alphatic esters in the presense of sodium alkoxide as a catalyst in an aromatic hydrocarbon solvent is reported.The different β-diketones can be obtained with high yields and purity.The crude materials was commercially available.The process is facile and can permit efficient recirculation of solvent.
The experiments on testing the extraction properties of β-diketones are performed.The results indicate that these β-diketones can extract copper efficiently under certain condition and be potential to become extractant of copper.关键词
