1-苯基-3-甲基-4-三氟乙酰基吡唑酮-(5)(以下简作PMTFP,在反应式中用HA代表)系4-酰基吡唑酮-(5)类螯合萃取剂,这类萃取剂是Jensen于1959年首先提出的,1963年国内就开始将这类萃取剂应用于镧系元素的萃取和放射化学的分离分析中.国外自1965年以来也做了大量工作,迄今已用于50多个元素的萃取.实践证明,这是一类优良的萃取剂.4-酰基吡唑酮-(5)类萃取剂与中性磷类萃取剂的协萃体系也已开展了一些工作.其中以1-苯基-3-甲基-4-苯甲酰基吡唑酮-(5)(简作
1-Phenyl-3-methyl-4-trifluoroacetylpyrazolone- (5) (hereinafter referred to as PMTFP, represented by HA in the reaction scheme) Co-extractants, such extractant was first proposed by Jensen in 1959, 1963, China began to use such extractants in the separation of lanthanide extraction and radiochemical separation analysis has also been done since 1965 A large number of work, so far has been used for more than 50 elements of extraction. Practice has proved that this is a class of excellent extractants. 4-acyl pyrazolone - (5) extractants and neutral phosphorus extractant system Some work has also been done in which 1-phenyl-3-methyl-4-benzoylpyrazolone- (5)
