摘　　要：通过等体积浸渍法成功制备了AgNO_(3)/NaY吸附剂,并对其进行XRD、N2吸-脱附和ICP-AES等表征。将制备的AgNO_(3)/NaY应用于1,1,2,2-四氟乙基-2,2,2-三氟乙基醚(HFE-347)中的杂质1,1,1-三氟乙基-1,1,2-三氟乙烯基醚的吸附脱除研究。结果表明,4%-AgNO_(3)/NaY可将HFE-347中1,1,1-三氟乙基-1,1,2-三氟乙烯基醚的浓度由920 mg/kg降至82 mg/kg,去杂率高达91%,为HFE-347在高端领域的应用提供了技术支撑。AgNO_(3)/NaY Adsorbents were synthesized and characterized using XRD,N_(2)adsorption-desorption,and ICP-AES.The adsorption properties of AgNO_(3)/NaY were evaluated in the adsorptive separation of 1,1,1-trifluoroethyl-1,1,2-trifluorovinyl ether as the main impurity in 1,1,2,2-tetrafluoro-2,2,2-trifluoroethyl ether(HFE-347).The results show that 4%-AgNO_(3)/NaY readily reduces the concentration of 1,1,1-trifluoroethyl-1,1,2-trifluorovinyl ether in HFE-347 from 920 mg/kg to 82 mg/kg,i.e.,the impurity removal rate as high as 91%,which provides some guidance for promoting the applications of hydrofluoroethers in high-end fields.
