ACIDITY AND CATALYTIC PROPERTIES OF ZIRCONIUM PHOSPHITE Academic Article

abstract

• Zirconium phosphite has a layered structure similar to zirconium phosphate. The phosphite compounds behave as acid catalysts in alcohol dehydration reactions, but the nature of the acidic sites is unclear. Infrared spectra of zirconium phosphite samples heated in air showed three weak absorption peaks at 3480, 3535 and 3670 cm-1 in the OH stretching region. However, only the 3670 cm-1 peak was affected by methanol adsorption. Temperature programmed ammonia desorption profiles showed that the acid sites of zirconium phosphites are weaker than those of zirconium orthophosphate, but stronger than those observed for zirconium pyrophosphate. Nevertheless, high conversions of ethanol to ethylene were obtained. 1986.
