中文摘要：

合成了带13C同位素标记的酚型木素模型物——愈创木基丙三醇-β-愈创木基醚-[α-13C],模拟了硫酸盐法蒸煮过程,将合成的木素模型物和典型的半纤维素组成部分——木糖进行蒸煮,然后利用酸析沉淀木素、乙酸乙酯抽提等方法将蒸煮后的产物分级,并利用13C-NMR（13C-核磁共振波谱）和二维HMQC（异核多量子相干谱）对分级后的各个部分进行分析,研究传统硫酸盐法蒸煮过程中LCC的形成情况。研究发现：酚型木素模型物的中间产物和木糖衍生物（糖醛酸等）形成了少量苯甲醚键型LCC结构,这些新形成的LCC结构主要存在于乙酸乙酯抽提物中。

英文摘要：

Guaiacylglycerol - β- guaiacyl ether - [ α-13C] was synthesized as the phenolic type lignin model compound. Then they were cooked by kraft method in the presence of xylose. The black liquor from kraft cooking were classified into four fractions by acidfying precipitation and ethyl acetate extraction. Techniques of 13C - NMR and HMQC were applied to determine each of the fractions and to identify the newly formed LCC structures. The re- sults showed that there were few newly formed LCC structures in ethyl acetate extractive and the intermediate from phenolic type lignin model compounds was linked to the alditols from xylose with benzyl ether bond during kraft cooking.
