ABSTRACT:
An environmentally benign catalytic process for the production of sym-octahydroanthracene (sym-OHA) from sym-octahydrophenanthrene (sym-OHP) by ring-shift isomerization. Proton-form moralenite or partially dealuminated proton-form mordenite are effective catalysts for the selective formation of sym-OHA from sym-OHP. Y-zeolite and metal-ion exchanged Y-zeolites display lower selectivity towards Sym-OHA. The use of certain solvents can further improve the performance of the Y-zeolites and mordenites, particularly the selectivity of Y-zeolite catalysts. The sym-OHA is an useful product and can be converted by existing methods to various anthracene derivatives which are industrial chemicals in demand.
