Reactions of n‐hexenes on 80/100 mesh amorphous silica‐alumina have been studied in a plug flow reactor at 405°C, and compared with results previously obtained using HY and H‐ZSM‐5. The dominant primary reaction is skeletal isomerization while the initial selectivity for cracking is very low compared to that on the zeolite catalysts. The dimerization‐cracking reaction, the major cracking process on the zeolites, was not a primary reaction on amorphous silica‐alumina. This and the slowness of reactions leading to paraffins and dehydrogenated species is attributed to the small number of strongly acidic sites on the amorphous material.
