ACIDIC PROPERTIES AND CATALYTIC ACTIVITIES OF VARIOUS CYCLO-TETRAPHOSPHATES

Abstract

Cyclo-tetraphosphates with heavy metals which are known to have high catalytic activities were synthesized and investigated on their catalytic activities for the dehydration of 2-propanol. Specific surface area, acid strength, and acidity of various cyclo-tetraphosphates were also measured and the correlation between catalytic activities and physicochemical properties were discussed.
