Kinetics on the adsorption of n-butene onto the acidic OH groups existing in the small pores of ferrierite (FER) were studied between 233 and 253K by IR spectroscopy. The activation energies for the adsorption of 1-butene and cis-2-butene were estimated as 23.3 and 28.4kJmol -1 , while that of trans-2-butene was not obtained due to its rapid adsorption. The activation energy for adsorption...
Reactions of cis‐ and trans‐2‐butene adsorbed on deuterated ZSM‐5 and mordenite were studied by IR spectroscopy below 300 K. 2‐butene molecules hydrogen‐bonding to Brønsted acid sites (OD) reacted when the temperature was increased above 250 and 230 K on D‐ZSM‐5 and D‐mordenite, respectively. H/D isotope exchange reaction of Brønsted acidic hydroxy groups accompanied the isomerization of cis‐ to trans‐2‐butene,...
