Abstract
Mixed tetrahydropolycyclopentadienes are isomerized in the presence of anhydrous aluminum trichloride to form an additive suitable for use with a high energy missile fuel. The amount of aluminum trichloride present is such that the weight ratio of trichloride to the tetrahydropolydiene is in the range between from about 0.005 to about 0.75. Also the isomerization involves an inert solvent and is at a temperature between from about -20.degree. C to about 25.degree. C. Also anhydrous hydrogen chloride is present to facilitate the isomerization.
