ResumoThe thermal decomposition of ammonia-borane has been studied by thermogravimetry, differential thermal analysis, and decomposition product measurements. Vigorous decomposition with hydrogen evolution begins near 120°C and proceeds in stages as the temperature is increased to 200°C leaving a white residue. The composition of the residue was approximately BNH2.1 after heating to 170°C and BNH(0.8–1.2) after heating to 200°C The ??? spectrum gave evidence of further slow hydrogen loss above that temperature.
