Sorption of carbon compound vapours on porous solids

Abstract

The isotherms of a series of hydrocarbon compounds containing various functional groups and their fluorinated analogues have been examined, with silica gel and ferric oxide as adsorbents. The isotherms are compared and contrasted to find any variations due to substituting fluorine in place of hydrogen.In addition low pressure isotherms (at 20°C, 25°C and 30°C) were obtained for the systems ethyl alcohol/ferric oxide and trifluoroethanol/ ferric oxide. The validity of these results are discussed and, assuming their correctness, various factors which might give rise to them are suggested.
