- W2018873285 abstract "The catalytic activity of X-type zeolite exchanged by Ag+ was studied for the isomerization of 1-butene. The activity gradually increased with the degree of exchange up to ca. 60%, whereafter it rose steeply. A good correlation was found between the activity and the number of acid sites of H0 less than 3.3. Both preferences, that for the formation of cis-2-butene from 1-butene and that for the geometrical isomerization rather than the double bond shift, indicated that the reaction proceeds via a carbonium-ion intermediate formed on an acidic site. In the region of exchange around 40%, however, the cis/trans ratio in the 2-butenes produced was less than unity and a change in the reaction mechanism was suggested. Treatment with H2 enhanced the activity of exchanged zeolite by a factor of 102–103 without any change in the character of the reaction. These results were attributed to the formation of proton-X-zeolite by the replacement of Ag+ with a proton. This conclusion was confirmed by the analysis of deuterium exchange during the isomerization on D2-treated AgX." @default.
