Abstract

Changes in the composition of aluminum hypophosphite, calcium hypophosphite, and their mixtures with oxidizers after combustion in air under atmospheric pressure have been studied by X-ray photoelectron spectroscopy (XPS). It has been established that the formation of colored condensed combustion products is associated with the formation of the corresponding phosphides. A hypothesis is proposed that the source of phosphide formation is phosphine and its reactive decomposition products generated during the disproportionation reaction of hypophosphites.

次磷酸铝和次磷酸钙凝聚燃烧产物的x射线光电子能谱

用x射线光电子能谱（XPS）研究了次亚磷酸铝、次亚磷酸钙及其与氧化剂混合物在常压空气中燃烧后的组成变化。已经确定，有色凝聚燃烧产物的形成与相应磷化物的形成有关。提出了一种假说，认为磷化物的形成来源是次磷酸盐歧化反应中产生的磷化氢及其反应分解产物。

期刊介绍： Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
