The transformations of 1, 2-diols over perfluorinated resinsulfonic acids (Nafion-H) were studied, and correlation were examined between the structures of the investigated diols, the possible dehydration routes and the catalytic properties of Nafion-H. Comparisons were also made between the catalytic properties of Nafion-H and NaHX zeolite. Because of its stronger acidity, Nafion-H functions at temperatures considerably lower than those for the usual ...
