摘要：

When 1-butene is converted over a fluorinated alumina catalyst, the theoretical yield of isobutene is lowered by a number of side reactions: dimerization into C-8, transformation into C3 and C5, hydrogen transfer and coking. The amount of the byproducts depends upon temperature, feed composition, contact time and time-on-stream. Conditions ensuring a high isobutene selectivity together with a slow catalyst deactivation are derived.
