1-苯基-3-甲基-4-酰基-5-吡唑酮对于金属离子是一类优良的螯合萃取剂,其在稀土分析化学中的应用已有综述。1908年Michae1is最先合成了1-苯基-3-甲基-4-苯甲酰基-5-吡唑酮,1959年Jensen又合成了一系列1-苯基-3-甲基-4-酰基-5-吡唑酮类化合物并
1-Phenyl-3-methyl-4-acyl-5-pyrazolone is an excellent chelating extractant for metal ions and its application in rare earth analytical chemistry has been reviewed. In 1908, Michae1is first synthesized 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone. In 1959, Jensen synthesized a series of 1-phenyl-3-methyl-4- -5-pyrazolone compounds
