PURPOSE:To effect isomerization of an olefin in the presence of a solid base catalyst to produce a stabilized inner olefin with high catalyst activity in high yield without formation of by-products such as polymers. CONSTITUTION:In the production of a stabilized inner olefin by isomerization of an olefin, a solid base is used as a catalyst, which is prepared by heating a hydrated alumina containing 1.2-10wt.%, preferably 2-7wt.% of water together with an excessive equivalent amount, preferably 1.01-2 equivalents of an alkali metal hydride based on the moles of the water in the alumina, in moisture-activated atmosphere at 200-500 deg.C, preferably 250-450 deg.C for 15 min-10hr. The amount of the catalyst used is 1/3,000-1/20wt. based on the feed and the isomerization is carried out at -80-120 deg.C, preferably -10-100 deg.C. |
