摘　　要：以六氟丙烯为原料 ,经连续气固相氢氟化反应制备了七氟丙烷 ,并对工艺参数进行了系统的研究。在较佳的催化剂中 ,当六氟丙烯通过每 kg催化剂的流量为 0 .33～ 0 .35kg/h、酸烯比为 1 .3～ 1 .5、反应温度为2 1 0℃时 ,粗品气中的七氟丙烷含量≥ 98.5%。H heptafluoropropane (F 227) was prepared from hexafluoropropene (HFP) and HF by a continuous hydrofluorinating reaction in a gas solid phase system, and the technology was systematically studied. When the better catalyst is used, the flux of HFP is 0.33~0.35 kg/h, the molecular ratio of HF to HFP is 1.3~1.5, and the reaction temperature is ≥210℃, the F 227 content in the crude gas reaches ≥98.5%.
