PREPARATION OF CHLOROTRIFLUOROETHYLENE TELOMERS WITH FLUOROXYTRIFLUOROMETHANE AND BISFLUOROXYDIFLUOROMETHANE

Abstract

Abstract Translated from French L'INVENTION CONCERNE LA PREPARATION DE TELOMERES DE CHLOROTRIFLUOROETHYLENE AVEC LE FLUOROXYTRIFLUOROMETHANE ET LE BISFLUOROXYDIFLUOROMETHANE. ON PREPARE LES TELOMERES EN FAISANT REAGIR LE CHLOROTRIFLUOROETHYLENE AVEC LE FLUOROXYTRIFLUOROMETHANE OU LE BISFLUOROXYDIFLUOROMETHANE. LA REACTION DE TELOMERISATION EST CONDUITE SOIT DANS DU CHLOROTRIFLUOROETHYLENE LIQUIDE SANS SOLVANT SOIT EN SOLUTION. LES TELOMERES AINSI FORMES PEUVENT EVENTUELLEMENT ETRE FLUORES PAR REACTION AVEC UN AGENT DE FLUORATION APPROPRIE POUR AMELIORATION DE LEUR STABILITE. UTILISATION DES TELOMERES COMME FLUIDES POUR DES SYSTEMES HYDRAULIQUES. THE INVENTION CONCERNS THE PREPARATION OF CHLOROTRIFLUOROETHYLENE TELOMERS WITH FLUOROXYTRIFLUOROMETHANE AND BISFLUOROXYDIFLUOROMETHANE. TELOMERS ARE PREPARED BY REACTING CHLOROTRIFLUOROETHYLENE WITH FLUOROXYTRIFLUOROMETHANE OR BISFLUOROXYDIFLUOROMETHANE. THE TELOMERIZATION REACTION IS CONDUCTED EITHER IN LIQUID CHLOROTRIFLUOROETHYLENE WITHOUT SOLVENT OR IN SOLUTION. THE TELOMERS SUCH FORMED MAY POSSIBLY BE FLUORINATED BY REACTION WITH AN APPROPRIATE FLUORINATION AGENT TO IMPROVE THEIR STABILITY. USE OF TELOMERES AS FLUIDS FOR HYDRAULIC SYSTEMS.
