    • PURPOSE: A continuous preparation of perfluoroethyliodide denoted by C2F5I under room pressure is accomplished with solid catalyst. The compound is used in a variety of water/oil repellent process or contaminant-resistant agents and high performance surfactant. CONSTITUTION: A continuous preparation of perfluoroethyliodide is performed by using iodide, pentafluoroiodide, tetrafluoroethylene(TFE) and reaction catalyst. The preparation comprises further continuously introducing TFE under room pressure and in the presence of iodide, iodide pentafluoride(IF5), antimony trifluoride(SbF3) and antimony oxide reaction catalyst in solid state to produce perfluoroethyliodide product. The iodide and iodide pentafluoride is admixed together in a reaction molar ratio (I2/IF5) of 0.02-5 and any one of the reaction catalyst SbF3 and Sb2O3 is dissolved under stirring at room temperature to 50 deg.C.
    • 目的:用固体催化剂在室温下连续制备由C2F5I表示的全氟乙基碘。 该化合物用于各种防水/拒油工艺或耐污染剂和高性能表面活性剂。 构成:通过使用碘化物,五氟碘化物,四氟乙烯(TFE)和反应催化剂,连续制备全氟乙基碘。 该制剂包括在室温下,在碘化物,五氟化碘(IF5),三氟化锑(SbF 3))和氧化锑反应催化剂的存在下,在固态下进一步连续引入TFE以制备全氟乙基碘产物。 以0.02-5的反应摩尔比(I 2 / IF 5)和碘化五氟化碘混合在一起,在室温至50℃的搅拌下将任何一种反应催化剂SbF 3和Sb 2 O 3溶解。
