Description
Summary:—The impurity composition of diborane synthesized by the hydrogenation reaction of boron chloride was studied for the first time with the chromatography–mass spectrometry method. A GS-GasPro 60 m × 0.32 mm capillary column with silica gel as a sorbent, a GS-CarbonPLOT 25 m × 0.32 mm × 0.25 μm column with a carbon sorbent, and a DB-5MS 30 m × 0.32 mm × 0.25 μm column with methylsiloxane were used to separate impurities. The impurities were identified by comparing their mass spectra with those from published data. The impurities of B 4 –B 10 higher boranes, cyclohexane, and toluene were identified in diborane. B 6 –B 10 boranes, cyclohexane, and toluene were found for the first time. The mass spectrum of B 9 H 15 , which was not found in the literature, was obtained and described.
