With the increase in heat-treated rubberwood used in interior decoration materials, the odorous constituents have attracted people’s attention. In this study, a headspace solid-phase microextraction method coupled with gas chromatography–mass spectrometry was employed to analyze the odorous constituents released from heat-treated rubberwood and the gaseous components from the heat treatment process. The results showed that the odorous constituents were classed into aldehydes, esters, ketones, acids, alcohols, phenols, alkanes, aromatics, and others. During the four-month test period, the emissions of aldehydes (47.08% and 65.66%) were the most dominating compounds in VOCs emission from F180 °C and F200 °C. The changes in chemical structure of rubberwood before and after heat treatment were investigated by X-ray photoelectron spectroscopy. It was found that the O/C ratio of rubberwood decreased from 0.52 to 0.44 after heat treatment with increasing temperature; the contribution of C 1 and C 2 peaks is more important than C 3 and C 4 . With increasing treatment temperature, the C 1 contribution of rubberwood samples increased from 34.37 to 42.47%, whereas the C 2 decreased markedly from 55.50 to 48.24% and the C 3 began to decrease at higher temperature. These results corresponded to variations observed from the gas chromatographic mass spectrometry results of heat-treated rubberwood.

HS-SPME 和 GC-MS 用于分析热处理橡胶木的气味成分和通过 XPS 分析热处理橡胶木的化学变化

随着室内装饰材料中使用的热处理橡胶木的增多，其异味成分引起了人们的注意。在本研究中，采用顶空固相微萃取法结合气相色谱-质谱法分析了热处理橡胶木释放的异味成分和热处理过程中的气态成分。结果表明，气味成分分为醛类、酯类、酮类、酸类、醇类、酚类、烷烃类、芳烃类等。在四个月的测试期间，醛的排放量（47.08% 和 65.66%）是 F180 °C 和 F200 °C VOCs 排放中最主要的化合物。通过X射线光电子能谱研究了热处理前后橡胶木化学结构的变化。发现橡胶木经热处理后的O/C比随着温度的升高而从0.52下降到0.44；C 1 和C 2 峰的贡献比C 3 和C 4 更重要。随着处理温度的升高，橡胶木样品的C 1 贡献从34.37%增加到42.47%，而C 2 从55.50%显着降低到48.24%，并且C 3 在较高温度下开始降低。这些结果对应于从热处理橡胶木的气相色谱质谱结果中观察到的变化。而C 2 从55.50 显着下降到48.24%，C 3 在较高温度下开始下降。这些结果对应于从热处理橡胶木的气相色谱质谱结果中观察到的变化。而C 2 从55.50 显着下降到48.24%，C 3 在较高温度下开始下降。这些结果对应于从热处理橡胶木的气相色谱质谱结果中观察到的变化。
