PURPOSE:To improve catalytic activity and to obtain the aimed compound with a small amount of catalyst and efficiently in producing a stable inner olefin, by isomerizing an olefin, by using a solid basic catalyst obtained by treating alumina with an alkali metal at a specific temperature. CONSTITUTION:In producing a stable inner olefin by isomerizing the double bond of olefin, hydrous alumina especially hydrous alumina of gamma-, x- rho-type having large surface area is heat-treated with >=equivalent based on water mol amount of the alumina, preferably 1.01-2 equivalents based on the alumina of an alkali metal in an inert gas atmosphere at 180-350 deg.C, preferably 200-300 deg.C to give a solid basic catalyst. The solid basic catalyst is used and the aimed compound is obtained with an extremely smaller amount of catalyst than by a conventional procedure, in a remarkably high efficiency, in high yield, safely, industrially and advantageously without causing by-products such as polymers, etc., and danger such as ignition, etc. |
