在高压喷射搅拌反应器中，对正庚烷氧化反应进行了实验研究，考察了低温和高温氧化条件（550-1150 K，1-40 atm，phi = 1）。反应物，中间体和最终产品已被测量在三个不同的氧化制度，即冷焰，负温度系数，和正常燃烧。测定了低温下生成的主要环醚的浓度分布。从低温到高温氧化制度的过渡作为压力的函数的演变进行了观察，显示在40大气压的负温度系数的准消失。结果解释的反应机理。
Normal heptane oxidation in a high-pressure jet-stirred reactor has been investigated experimentally in a wide range of conditions covering the low- and high-temperature oxidation regimes (550-1150 K, 1-40 atm, phi = 1). Reactants, intermediates, and final products have been measured in three different oxidation regimes, namely cool flame, negative temperature coefficient, and normal combustion. Concentration profiles of the major cyclic ethers formed at low temperature have been measured. The evolution of the transition from low to high temperature oxidation regime as a function of pressure was observed showing the quasi-disappearance of the negative temperature coefficient at 40 atm. The results are interpreted in terms of reaction mechanism.
