Abstract
The present invention relates to a process for producing an olefin, including the step of subjecting an aliphatic primary alcohol having 12 to 24 carbon atoms to liquid phase dehydration reaction in the presence of a solid acid catalyst, wherein among a total acid content of the solid acid catalyst as measured by an ammonia temperature-programmed desorption (NH3-TPD) method, an acid content of the solid acid catalyst as calculated from an amount of ammonia desorbed at a temperature not higher than 300° C. in the method is 70% or larger of the total acid content.
