Notes:
Abstract 1H MAS-NMR spectroscopy reveals analogies between partly dehydrated samples of silica-alumina and strongly dealuminated HY zeolite. There is a fundamental difference between the dehydration processes of crystalline and amorphous samples. A scheme for the reactions occurring during dehydration and dehydroxylation is proposed.
