名称：三氟乙酸银 silver trifluoroacetate
无色固体，用氧化银和三氟乙酸制取。
silver trifluoroacetate can be prepared by adding trifluoroacetic acid to a slight excess of suspended silver hydroxide, filtering, evaporating to dryness, grinding to a powder, and completing the desiccation in vacuo, on a steam-bath. the pure, dry salt is not sensitive to light.
from commercial sodium trifluoroacetate, an alternate method consists in dissolving silver nitrate in an equal amount of water, adding an equimolecular quantity of sodium trifluoroacetate, and extracting with portions of ether of about equal volume. vigorous agitation for thirty minutes on a mechanical shaker is recommended as the difference in density tends to keep the layers apart. after three extractions, it is well to distil off as much water as can be taken from the aqueous layer without causing crystallizing out, because the crystals are a mixture of sodium nitrate and silver trifluoroacetate. the extraction is then repeated with three portions of ether. on distillation, the ether solution leaves a mushy residue of silver salt and ether, which must be desiccated in vacuo on the steam-bath, as above.
