Abstract

The activation of H3PW12O40 under different thermal conditions has been evaluated by calorimetry in acetonitrile solution using pyridine as a probe, and the results correlated to the dehydration of 1-propanol. Treatments at 200, 300, and 400 °C show substantial changes in the catalytic activity of 12-tungstophosphoric acid as a function of activation temperature and time. Analysis of the samples by XRD, FTIR, TGA and DSC was performed to determine structural changes and thermal stability of the heteropolytungstic acid.
