maghnia or mostaganem bentonites , are activated by contacting the maghnia or mostaganem bentonite with an acid solution of selected concentration and then drying the maghnia or mostaganem bentonite to form an activated bentonite catalyst . this activated bentonite catalyst may be used to polymerize a vinyl , acrylic , cyclic ether , aldehyde , lactone or olefin monomer . in a further embodiment , a perflourinated amine or diamine is synthesized by contacting a maghnia or mostaganem bentonite with an acid solution of selected concentration , drying the maghnia or mostaganem bentonite , and absorbing a secondary amine with the maghnia or mostaganem bentonite to form a perflouroamide iodide salt . the perflouramide idodide salt can then be extracted with a polar solvent and neutralized by the use of a basic solution .
