Abstract
The porosity of gamma-alumina-based materials is an important paramete r affecting the extent of fluorination (aerogels > commercial gamma-Al 2O3 > xerogels) and, consequently, also the textural, acidic and catal ytic properties of the final fluorinated materials. Only the highly fl uorinated aluminas having strong Lewis acidic sites catalyse the isome risation of CHF2CHF2 to CF3CH2F.
