1-苯基-3-甲基-4-酰基吡唑酮(5)是金属离子的一类优良萃取剂,其在稀土分析化学中的应用已有综论。Michaclis早期合成了1-苯基-3-甲基-4-苯甲酰基吡唑酮(5),Jensen1959年合成了一系列的1-苯基-3-甲基-4-酰基吡唑酮(5)化合物并研究了它们的结构和应用。我们以1-苯基-3-甲基吡唑酮(5)和酰氯为原料分别以氢氧化钙和氧化钙为缩合剂,无水乙醇或二氧六环为溶剂合成了四个1-苯基-3-甲基-4-酰基吡唑酮(5)化合物,其 1-Phenyl-3-methyl-4-acyl pyrazolone (5) is a class of excellent extractants for metal ions and its application in the analysis of rare earth metals has been reviewed. Michaclis early synthesized 1-phenyl-3-methyl-4-benzoylpyrazolone (5), Jensen 1959 a series of 1-phenyl-3-methyl-4-acyl pyrazolone ( 5) compounds and studied their structure and application. We use 1-phenyl-3-methyl pyrazolone (5) and acid chloride as raw materials were calcium hydroxide and calcium oxide as a condensing agent, anhydrous ethanol or dioxane as a solvent to synthesize four 1-benzene 3-methyl-4-acyl pyrazolone (5) compound
