用傅里叶变换红外光谱(FT-IR)研究了煤的低温氧化过程。样品在140℃和60℃下氧化几小时到几天。这些FT-IR。结果与吉塞尔塑性仪测量的煤的热塑性性质的变化相关。作为氧化时间函数的吉塞尔流动性的损失对应于脂肪族CH基团的损失。用曲线分辨方法区分不同的C=0官能团。在这两种氧化温度下，羰基和羧基总体上都增加了，但根据氧化温度的不同，其相对比例不同。
The low-temperature oxidation of coal has been investigated by Fourier transform infrared spectroscopy (FT-i.r.). Samples were oxidized at 140 and 60 °C for intervals of a few hours to days. These FT-i.r. results were correlated to changes in the thermoplastic properties of the coal measured by a Gieseler plastometer. The loss of Gieseler fluidity as a function of oxidation time corresponds to loss of aliphatic CH groups. Curve-resolving methods were used to distinguish between various C = 0 functional groups. At both oxidation temperatures there was an overall increase in carbonyl and carboxyl groups, but in different relative proportions depending on the oxidation temperatures.
