摘要：

The IR spectra of 1-hexanol adsorbed on SAPO-5 molecular sieves and on HZSM-5 zeolite were compared. It has been found that both types of catalysts activate at 423 K the dehydration of 1-hexanol. In the IR spectra bands at 670 cm-1 (Z-isomer), 889 cm-1 (CH2 = C< fragment), 911 cm-1 (CH2 = CH-) and 965 cm-1 (E-isomer) have been observed, indicating that the skeletal and positional isomerization took place. A carbonyl compound (1 730 cm-1) was formed at room temperature on all the investigated catalysts and disappeared upon heating, The activity of HZSM-5 in olefin isomerization and in dehydrogenation was greater than that of SAPO-5.
