SYNTHESIS OF TETRAHYDROFURAN OVER ALUMINOPHOSPHATE ALPO-11 CATALYSTS


Shyamji Gurjar, Udaypal Singh Thakur, Radha Tomar

Abstract


Crystalline AlPO-11 and its metal substituted CoAlPO-11 was prepared by the hydrothermal method and characterized by X-ray diffraction, scanning electron microscopy, Fourier transform infrared (FT-IR) spectroscopy and ICP-AAS. All the samples crystallized with the AFI structure. The catalytic properties of the catalysts in cyclodehydration of 1, 4-butandiole to THF. CoAPO-11 with more Lewis acid sites, and stronger Bronsted acid sites gave better activity than AlPO-11.

Keywords: Metal substituted aluminophosphate molecular sieve, Butanol, THF.
