Abstract—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 B4–B10 higher boranes, cyclohexane, and toluene were identified in diborane. B6–B10 boranes, cyclohexane, and toluene were found for the first time. The mass spectrum of B9H15, which was not found in the literature, was obtained and described.
期刊介绍：
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
