Dehydrofluorination of hydrofluorocarbon-134 (CF2HCF2H) occurs over the basic zeolite NaX at 275 deg C, to produce HFC-1123 (CF2CFH) and tetrahedrally-coordinated aluminum fluoride species.Under moist conditions, the tetrahedral aluminum fluoride species are hydrolyzed and six-coordinate species are formed.The framework of the less basic zeolite NaY is not attacked by HFC-134 under similar conditions.
