CATALYTIC CONVERSION OF ETHYL-ALCOHOL ON POLYANILINE PROTONATED WITH 12-TUNGSTOSILICIC ACID

It has been demonstrated that protonation of polyemeraldine base with 12-tungstosilicic acid leads to the preparation of a new, polymer supp orted catalyst which shows significantly higher activity and altered s electivity in ethyl alcohol conversion as compared to crystalline 12-t ungstosilicic acid studied in the same experimental conditions. The im proved activity is associated with higher dispersion of Keggin units b onded to the polymer surface via protonation reaction which in tum lea ds to their improved thermal stability as shown by DTA, FTIR and other studies.
