Abstract
Isomerization of a liquid, saturated endo-endo norbornadiene hexacyclic dimer involves the use of a catalytic amount of acidic alumina or a montmorillonite. The resulting isomeric product is solid, at ambient temperature, and can be used as a missile fuel.
Claims4
Process for the isomerization of a saturated endo-endo norbornadiene hexacyclic dimer comprising contacting a hexacyclic dimer having the following structure:
- ##STR5## with a catalytic amount of acidic alumina or a montmorillonite at an isomerization temperature until an isomer is formed.
