Abstract
Aliphatic monoolefins which can be normal or branched are isomerized at temperatures in the approximate range 500.degree.-1200.degree. F. in presence of a high surface area activated alumina containing a relatively low amount of sodium oxide (Na.sub.2 O) to form 1-olefin. Generally, from about 0.13 to about 0.39 milliequivalents of Na.sub.2 O per gram of the activated alumina containing the Na.sub.2 O, supplied by such sodium compounds as are disclosed, the activated alumina having a large surface area, i.e., about 300-400 m.sup.2 per gram, is used as a catalyst for the isomerization of, say, isomeric n-butenes. Generally, the olefin treated will have from 4 to about 20 carbon atoms per molecule.
