【Abstract】 Six novel type extractant dialkylphosphoamidate(see Tab. 1) were synthesized. A series of extraction experiments were carried out for separation of acetic acid from dilute solution by the title compounds in the mixture of 1octanol and kerosene. The mechanism of the extraction has been studied by IR and NMR spectrometry.更多还原
