Infrared study of cyclohexanol chemisorption in SAPO molecular sieves
Abstract
The infrared spectra of cyclohexanol adsorbed on SAPO molecular sieves (four SAPO-5 samples with different SiO2 contents, SAPO-11 and SAPO-31 were studied) show bands due to cyclohexanone (1732 cm–1) at room temperature, while on heating cyclohexene is formed. The results are discussed in terms of the existence of basic sites parallel to the Brønsted acid sites.
