摘要偶氮类化合物（分子中含有-N=N-）是一类重要的有机化合物，在人们的日常生活和现代科技方面具有重要的应用价值。通常作为制备聚合物时的引发剂、发泡剂和催化剂，在聚合物的制备、废水处理、冶金分析、钢铁防腐、药物载体等方面有着广泛的应用；尤其是最近作为引发剂，包括油溶性、水溶性引发剂、偶氮酯类引发剂等，得到了较快发展。但其分子结构上具有弱键，发生热分解时产生自由基和氮气。因此在高温下具有一定的热危险性，很容易发生燃烧爆炸事故，造成财产损失。在本课题研究中，我们着重研究其燃烧特性，结合实验室条件，利用常规火焰燃烧特性测量装置，通过测量常用油溶性偶氮类引发剂——偶氮二异丁腈燃烧的火焰温度、火焰形状、燃烧过程中的质量损失速率等参量，归纳总结其燃烧特性，为防治此类物质可能引发的燃烧危害打下良好基础。63643

Title Experimental study of combustion characteristics of commonly used oil-soluble azo initiator
Abstract Azo compounds (Molecules containing-N=N- ) are an important class of organic compounds and have important application value in people's daily lives and modern technology. They, often used as initiator, blowing agent and catalyst, have a wide range of applications in the preparation of the polymers, waste water treatment, metallurgical analysis, steel corrosion, drug carrier and so on; Especially as the initiator, including oil-soluble, water-soluble initiator, azo ester initiator, etc, have been rapid development. But they have a weak bond in its molecular structure and generate free radicals and nitrogen when occur thermal decomposition. So at high temperatures they have heat risk, it is prone to combustion explosion, resulting in property damage. In this research, we focus on the combustion characteristics, combined with laboratory conditions , using conventional flame combustion characteristics measuring device, by measuring the flame temperature , flame shape, mass loss rate of the combustion process and other parameters of the commonly used oil-soluble azo initiators -- AIBN , summarized its combustion characteristics , lay a good foundation for the prevention and treatment of such substances may lead to fire hazard .
Keywords: Azo initiators, hot risk, combustion characteristics
