(diorganylphosphoryl) 4 methylpentan 2 ones (I) can be used as fire retardants for poly(vinyl chloride), the best results having been obtained for diarylphos phoryl compounds [1]. Later, phosphorylmonoke tones of type I have been demonstrated to be efficient extractants of lanthanides from acid solutions, better than such a known bidentate organophosphorus extractant as N,N dibutylcarbamoylmethylphosphine
35 含有氧代烷基取代基的官能化氧化膦,其中磷酰基和羰基被乙烯片段分开,最近引起了很多关注。例如,4(二有机磷酰基)4甲基戊烷2(I)可用作聚(氯乙烯)的阻燃剂,二芳基磷酰基化合物已获得最佳结果[1]。后来,I 型磷酰单酮已被证明是从酸溶液中提取镧系元素的有效萃取剂,优于已知的双齿有机磷萃取剂,如 N,N 二丁基氨基甲酰基甲基氧化膦 Ph2P(O)CH2C(O)N(Bu n)2 [2 ]。
