摘要

为揭示不同聚合度的聚甲氧基二甲醚（PODE）各组分反应活性随聚合度变化的规律及动力学机理，构建了适用于广泛工况的反应路径框架，对比分析了PODE多组分反应动力学行为。基于二甲氧基甲烷（PODE

）的反应机理，构建了PODE

、PODE

的反应机理，并对该反应机理进行了验证。根据各基元反应的反应动力学作用，提出PODE反应路径统一框架，阐明了PODE反应活性的3个来源通道：伯碳脱氢后通过两次加氧发生的典型链分支反应，部分氢过氧燃料自由基分解为羰基氢过氧化物的链分支反应，仲碳脱氢分解为低聚合度燃料自由基后发生的链分支反应。PODE在第一阶段点火延迟时间的敏感性分析结果表明，构建的PODE

、PODE

的反应动力学机理能够预测实验测量的点火延迟时间，可以对PODE的反应动力学行为作出解释。通道1和通道2是所有PODE分子所共有的链分支反应通道，而通道3是高聚合度PODE所特有的反应路径，是重要的反应活性贡献来源。

Abstract

To reveal the variation law of reaction activity of polyoxymethylene dimethyl ethers (PODE) components with different polymerization degrees and the underlying kinetic mechanisms

a reaction pathway framework applicable to a

wide range of conditions is constructed to comparatively analyze the multi-component reaction kinetic behaviors of PODE. Based on the reaction mechanism of dimethoxymethane (PODE

)

the reaction mechanisms of PODE

and PODE

are developed and validated. According to the role of each elementary reaction in reaction kinetics

a unified framework for PODE reaction pathways is proposed

elucidating three source channels of PODE reactivity: the typical chain-branching reaction via primary carbon dehydrogenation followed by two oxygen additions; the chain-branching reaction resulting from the decomposition of some hydroperoxy fuel radicals into carbonyl hydroperoxides; the chain-branching reaction triggered by secondary carbon dehydrogenation and decomposition into lower-polymerization-degree fuel radicals. Sensitivity analysis of the first-stage ignition delay time of PODE demonstrates that the constructed reaction kinetic mechanism of PODE

and PODE

can predict experimentally measured ignition delay times and explain the reaction kinetic behaviors of PODE. Channels 1 and 2 are common chain-branching reaction pathways for all PODE molecules

while channel 3 is unique to higher-polymerization-degree PODE and serves as an important contributor to reactivity.
