摘要: A series of highly fluorinated compounds the type {CF3(CF2)5CH2CH2}3P=O, [{CF3(CF2)5CH2CH2}2P(E)CH2CH2P(E){CH2CH2(CF2)5CF3}] and {CF3(CF2)5CH2CH2}2C=E (E = O or S) have been examined for their ability to extract gold(III) from aqueous solutions. The phosphine oxides studied under liquid–liquid extraction conditions water into perfluorohexane found give poor distribution ratios. bidentate oxide, ketone thioketone were solid–liquid substantially better with up 80% Au(III). In addition, crystal structure {CF3(CF2)5CH2CH2}3P=O has determined.
