指出调聚法制备全氟碘代烷的关键主要在以下 2 个方面 :提高反应器单位产出率 ,降低生产成本 ;提高终产物的选择性 ,减少碳中图分类号 : TQ316133文献标识码 :A文章编号 :0253 - 4320 (2025) 06 - 0018 - 04Advances in mechanism and processes of telomerization of perfluoroalky iodidesXI Xian2f eng , ZHOU Xiao2hong , WU Zhou2an , L EI Zhi2gang , GU Yong2hong(National Engineering Research and Development Center for Fluorine2containing Material Abstract : The mechanism of the telomerization of perfluoroalky iodides is illuminated
The processes of perfluoroalkyiodides by gas phase ,catalyst and radical telomerization are discussed
It is pointed out that two keys to perfluoroalky iodides produced by the telomerization processes are as follows
