Borazine is a promising precursor for boron nitride. A detailed investigation on the reaction of sodium borohydride and ammonium sulfate from 40 °C to 120 °C for synthesis of borazine was performed. The reaction was monitored by means of 11B nuclear magnetic resonance (11B NMR) and Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), mass spectroscopy (MS). The reaction produces
硼嗪是氮化硼的有前途的前体。进行了硼氢化钠与硫酸铵在40°C至120°C反应中合成硼嗪的详细研究。通过11 B核磁共振(11 B NMR)和傅里叶变换红外光谱(FTIR),X射线衍射(XRD),质谱(MS)监测反应。在低于60°C的温度下,该反应主要生成氨硼烷(AB),但不生成硼嗪。温度的升高促进了硼嗪的产量,硼嗪的产量在110°C左右达到最大值。而温度的进一步升高导致硼嗪的严重聚合,因此抑制了硼嗪的收率。
