摘要：

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