The kinetics of dehydration were studied in a flow reactor, the obtained activation energy values being 50-107 kJ/mol, and the pre-exponential factor 104- 1013s -1. The nature of the external cation does not influence the dehydration kinetics essentially. The activation energy and pre-exponential factor values increase on transition from the high-hydrated tungstates to the low-hydrated molybdates Доп.точки доступа: Gavrilova, G. V.; Maksimova, L.
