在本研究中，有机溶剂木质素的快速热解进行了分析热解耦合气相色谱和质谱检测器。热解产物包括酚类、呋喃类、直链酸或酯，以及少量的醇和乙酸。酚类化合物是主要产物，在不同温度下，随着保温时间的延长，酚类化合物的产率变化不明显。但后续试验表明，快速热解和快速缩合更有利于酚类化合物的生成。丙烷侧链在不同位置的断裂导致不同的产物形成。Cα-Cβ键最容易断裂，形成醛基，生成香草醛和香草醛的量最多。C4-Cα键断裂生成愈创木酚和姜子酚是芳香骨架降解中最难的反应。
In this study, fast pyrolysis of Organosolv lignin was carried out on an analytical pyrolyzer coupled with gas chromatography and mass spectrometry detectors. The pyrolytic products included phenols, furans, linear acids, or esters, as well as a small amount of alcohol and acetic acid. Phenolic compounds were main products, whose yields changed not obviously at different temperature with holding time increasing. But the successive tests showed that the fast pyrolysis with rapid condensation extensively favored the formation of phenolic compounds. The breakage of propane side chain at different positions led to various formations of products. The Cα-Cβ bond was easiest to break and formed aldehyde group, which produced the most abundant products of vanillin and syringaldehyde. The breakage of C4-Cα bond to form guaiacol and syringol was the most difficult reaction in the aromatic skeleton degradation.
