聚甲醛二甲醚（POMDME）的化学通式为CH_3 O（CH_2 O）_nCH_3（n>1），是一种具有显著降烟潜力的含氧替代燃料。采用实验和模型相结合的方法，研究了n = 3的POMDME 3 [CH_3 O（CH_2 O）_3CH_3]的燃烧动力学。26种物种，包括一些自由基和活性中间体，被确定和定量在低压层流预混POMDME 3火焰与同步辐射真空紫外光电离质谱。在常压球形爆发器中测量了当量比为0.7 ~ 1.6的POMDME 3/空气混合物的层流燃烧速度。建立了POMDME 3的高温燃烧化学动力学模型，并考虑了实验和模型预测的不确定性，对模型进行了验证。此外，通过对反应途径的模型分析，揭示了POMDME 3的消耗过程和一些关键中间体的形成机理。在（C-O）链结构中不存在碳-碳（C-C）键导致显著的烟灰减少潜力。相关的反应模式也可以适用于较大的POMDME化合物。
Poly(oxymethylene) dimethyl ethers (POMDMEs) with the general chemical formula of CH3O (CH2O)nCH3(n>1) are promising oxygenated alternative fuels with substantial soot-reduction potential. Combustion kinetics of the compound withn= 3, POMDME3[CH3O(CH2O)3CH3], was investigated in the present study with combined experimental and modeling efforts. Twenty-six species, including some radicals and reactive intermediates, were identified and quantified in a low-pressure laminar premixed POMDME3flame with a synchrotron vacuum ultraviolet photoionization mass spectrometry. Laminar burning velocities of POMDME3/air mixtures were measured in a spherical bomb at atmospheric pressure with the equivalence ratio ranging from 0.7 to 1.6. A kinetic model aimed at interpreting the high-temperature combustion chemistry of POMDME3was constructed and tested by all the measurements with uncertainties of both experiments and model predictions taken into consideration. In addition, model analysis of the reaction pathways was performed to reveal the consumption processes of POMDME3and the formation mechanisms of some crucial intermediates. The absence of carbon-carbon (C-C) bonds in the (C-O) chain structure results in significant soot-reduction potential. Relevant reaction patterns could also apply to larger POMDME compounds.
