Реферат:
The formation of alkenyl and alkylaromatic cations from methanol, olefin, diene and compounds with a single aromatic ring on H-ZSM-5 zeolites has been detected using IR and UV-Vis spectroscopy. The formation of alkenyl cations can be characterized reliably by the appearance of vCCCas bands at 1490–1530 cm−1 in IR spectra and bands at 290–310 (allyl), 350–380 (dienyl) and 430–450 (trienyl cations) nm in UV-Vis spectra. The formation of alkylaromatic cations can be characterized by the appearance of stretching vibrations of the aromatic ring at 1500 and 1600 cm−1 and bands at 320–330 and 400–440 nm, taking into account the thermal stability of surface complexes.
