Abstract
The invention relates to a method of selectively producing adamantanes in a production apparatus made of an inexpensive material, not having any negative influence on the natural environment. The method for producing adamantanes includes isomerizing a tricyclic saturated hydrocarbon having at least 10 carbon atoms in the presence of a metal-carrying solid acid catalyst, wherein an unsaturated bond-having compound is made to coexist along with the catalyst during the isomerization.
