Abstract

1 98.7: 1.3 TaF,/AlT, 51.9 9.9 38.2 31 69 2 99.1: 0.9 TaF, 15.5 3.0 81.5 91 9 3 99.1: 0.9 SbF,/graphite 64.1 31.5 4.4 96 4 a All values reported are in mole percentage. Catalysts pretreated with HF for 30 s. Excluding methane. Trace amounts of (CH,), SiF, detected in all runs are probably due to SiF, impurity from HF reacting with methane. thus it is derived from ethylene. e Isobutane contained no" C label, of olefins. These experiments are also not ...
