Abstract

Organometallic complexes of transition metals with inorganic anions are considered as promising precursors for the synthesis of nanoscale materials used in various applications including chemical catalysis. In this work, organometallic complexes of nickel, iron, and copper with imidazole as an organic ligand and the nitrate anion as an inorganic ligand were synthesized and characterized. The kinetic parameters of thermal decomposition of the synthesized organometallic complexes were determined by low heating-rate thermogravimetric analysis and high-speed dynamic mass spectrometric thermal analysis. The main gaseous products of thermal decomposition of the complexes under high-speed heating were identified. The chemical and phase compositions of condensed combustion products of the organometallic complexes in air were studied.

镍、铁和铜与无机阴离子的有机金属络合物热解动力学及气态产物的组成
摘要 过渡金属与无机阴离子的有机金属配合物被认为是合成包括化学催化在内的各种应用中使用的纳米级材料的有前途的前体。本研究以咪唑为有机配体,硝酸根阴离子为无机配体,合成了镍、铁和铜的有机金属配合物,并对其进行了表征。通过低加热速率热重分析和高速动态质谱热分析测定了合成的有机金属配合物的热分解动力学参数。确定了高速加热下络合物热分解的主要气态产物。研究了有机金属络合物在空气中冷凝燃烧产物的化学成分和相组成。

期刊介绍: Combustion, Explosion, and Shock Waves a peer reviewed journal published in collaboration with the Siberian Branch of the Russian Academy of Sciences. The journal presents top-level studies in the physics and chemistry of combustion and detonation processes, structural and chemical transformation of matter in shock and detonation waves, and related phenomena. Each issue contains valuable information on initiation of detonation in condensed and gaseous phases, environmental consequences of combustion and explosion, engine and power unit combustion, production of new materials by shock and detonation waves, explosion welding, explosive compaction of powders, dynamic responses of materials and constructions, and hypervelocity impact.
