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°C. and 186°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 exot...
A process for the thermolysis reaction of tetraethylammonium borohydride to yield bis(tetraalkylammonium) decahydrodecaborane which comprises: (i) combining Et4NBH4 in a mole ratio from about 0.3 to 1.0 with a boron-based solvent Et4NBH3 in a mole ratio from about 0.2 to 4.0 to form a reaction mixture, (wherein Et is C2H5), in a thermolysis reactor vessel having a plurality of outlets for various functions including an outlet for the introduction of reactants and an inert gas, an outlet through which the reaction temperature is monitored, and an outlet f...
