Trifluoromethane has been used in a gaseous fluorination of the aluminium form of zeolite Y in order to avoid removal of aluminium during fluorine modification, which was observed previously for the procedure with NH4F aqueous solution.The samples modified with CHF3 showed an increase in catalytic activity for reactions involving acid sites; however, the maximum activity was reached for much lower fluorine content and it was slightly lower than that for samples fluorinated with NH4F.
