A novel synthetic route to perfluoroisobutyronitrile from perfluoroisobutyryl acid which has mild conditions and low toxicity is described. This study introduces detailed synthetic protocols and characterization including GC-MS, 13C NMR and 19F NMR spectroscopy of perfluoroisobutyryl acid, perfluoroisobutyryl chloride, perfluoroisobutyl amide and perfluoroisobutyronitrile. Besides, this route is superior to the established patent and shows potential application in high voltage electrical equipment.

Paragraph 0119-0121, (2017/12/27)
The present invention relates to a reaction system for preparing tetrafluoroethane-andbeta;-sultone and to a preparation method using the same. By using the reaction system for preparing tetrafluoroethane-andbeta;-sultone and the preparation method using the same, tetrafluoroethane-andbeta;-sultone can be prepared safely and easily at a high yield and a high purity at normal temperature and normal pressure, rapid heat generation can be avoided and the risk of explosion in processes due to pressurization is reduced, so that the reaction system and the preparation method are usefully used to prepare energy-related materials such as fuel cell electrolytes and the like derived from tetrafluoroethane-andbeta;-sultone, and in particular, are usefully used to prepare fluorine-based ionomers.COPYRIGHT KIPO 2017
