摘要
摘要 首次采用色谱-质谱法研究了氯化硼氢化反应合成的二硼烷的杂质组成。采用以硅胶为吸附剂的 GS-GasPro 60 m × 0.32 mm 毛细管色谱柱、以碳为吸附剂的 GS-CarbonPLOT 25 m × 0.32 mm × 0.25 μm 色谱柱和以甲基硅氧烷为吸附剂的 DB-5MS 30 m × 0.32 mm × 0.25 μm 色谱柱分离杂质。杂质的鉴别方法是将其质谱图与已发表数据的质谱图进行比较。在二硼烷中鉴定出了 B4-B10 高级硼烷、环己烷和甲苯杂质。首次发现了 B6-B10 硼烷、环己烷和甲苯。获得并描述了文献中未发现的 B9H15 的质谱。
Identification of Impurities in Diborane by Gas Chromatography–Mass Spectrometry
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.
