Abstract

Ammonia borane synthesis via the sodium borohydride metathesis route in a liquid ammonia / tetrahydrofuran system was successfully scaled up to 10 gram batch at 15°C and 100 psia with near quantitive yield of high purity ammonia borane. No need for reactor heating or cryogenic cooling is an advantage for a low cost process. The use of liquid ammonia solvent should not impose much difficulty in process scale up since only mild pressure is needed to liquefy ammonia near room temperature.
