摘要: Extraction abilities of phosphorylketones with alkyl and cycloalkyl substituents at the phosphorus atom R2P(O)CH2CH2C(O)Me (R = Pri, But) R2P(O)CHPhCH2C(O)Me cyclo-C6H11) toward UVI, ThIV, a series tervalent lanthanides (LaIII, NdIII, HoIII, YbIII) were studied. The efficiencies selectivities recovery f-elements from nitric acid solutions to chloroform by these ligands compared extraction properties both model phenyl Ph2P(O)CH2CH2C(O)Me Ph2P(O)CHPhCH2C(O)Me other known extractants such as tributyl phosphate (BuO)3P(O), trioctylphosphine oxide (C8H17)3P(O), carbamoylphosphine Ph2P(O)CH2C(O)NBu2.
