Abstract
The relative acid strength of copper was evaluated by thermogravimetry (TG) and differential scanning calorimetry (DSC) methods, using n-butylamine as a molecular probe. The total acidity was calculated from TG curves whereas the relative acid strength was determined from DSC curves, using the Borch ardt-Daniels kinetic model. Acidity and active sites were measured by IR sp ectroscopy. (C) 1999 Elsevier Science B.V. All rights reserved.
