Disclosed is an improved method and the thermolysis equipment setup for converting tetraethylammonium tetrahydridoborane to bis(tetraethylammonium) decahydrodecaborane by a thermolysis reaction which increases the yield in the range between about 22% to 64%, and, perhaps higher. The heat transfer control is maintained by employing triethylamine borane in the reaction mixture between about 175 DEG C. and 186 DEG C. for a reaction time from about 1 hour to about 2.5 hours. The disclosed thermolysis procedure is successful in dissipating a major portion of the exothermic heat. The control of the generated heat serves to minimize the formation of the byproduct bis(tetraethylammonium) dodecahydrododecaborane while increasing the yield of the desired product, bis(tetraethylammonium) decahydrodecaborane.
