Abstract

Alkylphosphinates have received extensive attention in the past few decades because of their very useful mechanical properties, electrical properties, low density, and low toxicity, and have been widely used in flame-retardant materials and other fields. In this work, aluminum diethylphosphinate is successfully synthesized under atmospheric pressure. More importantly, two novel dialkylphosphinates, aluminum dioctylphosphinate and aluminum didecylphosphinate, are first synthesized and characterized. The structures of these aluminum dialkylphosphinates are confirmed by nuclear magnetic resonance, Fourier-transform infrared spectroscopy, and high-resolution mass spectrometry, and the microscopic morphology and thermal stability are analyzed by scanning electron microscopy and thermogravimetric analysis, respectively. Furthermore, conditions for the synthesis of aluminum dioctylphosphinate are optimized. Compared with the traditional method of synthesizing dialkylphosphinates under high pressure, the method reported in this paper has the advantages of high safety, easy operation, and low economic cost, which makes it suitable for industrial production.
常压下烷基膦酸铝的合成
烷基膦酸盐由于其非常有用的力学性能、电学性能、低密度、低毒等特点,在过去几十年中受到了广泛的关注,在阻燃材料等领域得到了广泛的应用。本研究成功地在常压下合成了磷酸二乙基铝。更重要的是,首次合成并表征了两种新型的二烷基膦酸盐:二辛基膦酸铝和二癸基膦酸铝。采用核磁共振、傅里叶变换红外光谱和高分辨率质谱技术对二烷基膦酸铝的结构进行了确证,并分别采用扫描电镜和热重分析对其微观形貌和热稳定性进行了分析。并对合成二辛基膦酸铝的工艺条件进行了优化。与传统高压合成二烷基膦酸盐的方法相比,本文所报道的方法具有安全性高、操作简便、经济成本低等优点,适合工业化生产。

期刊介绍: The Journal of Chemical Research is a peer reviewed journal that publishes full-length review and research papers in all branches of experimental chemistry. The journal fills a niche by also publishing short papers, a format which favours particular types of work, e.g. the scope of new reagents or methodology, and the elucidation of the structure of novel compounds. Though welcome, short papers should not result in fragmentation of publication, they should describe a completed piece of work. The Journal is not intended as a vehicle for preliminary publications. The work must meet all the normal criteria for acceptance as regards scientific standards. Papers that contain extensive biological results or material relating to other areas of science may be diverted to more appropriate specialist journals. Areas of coverage include: Organic Chemistry; Inorganic Chemistry; Materials Chemistry; Crystallography; Computational Chemistry.
