摘　　要：研究了木素前驱物松柏醇-β-D-葡萄糖苷-[α-13C]与木素模型化合物的聚合反应方法及其反应机理。采用红外分析、核磁共振等方法分析聚合产物的特性及形成机理。并用偏光显微镜测定产物是否具有旋光性,从而进一步分析产物的特性;采用GPC分析手段,来测定产物分子量的大小,通过分子量的变化来反映聚合的程度。研究表明:木素前驱物松柏醇-β-D-葡萄糖苷与木素模型物聚合的产物没有旋光性,分子量也大大地增加了,因此说明松柏醇-β-D-葡萄糖苷能与木素模型物聚合成大分子,为进一步研究木素前驱物松柏醇葡萄糖苷用于废水的研究奠定了基础。This paper study the mechanism and method of the polyreaction about coniferin with lignin model compound（β-O-4）. Analysis the characteristics and mechanism of polymerization product through FT-IR,C13- NMR and so on. Though polarized microscope to test the characteristics of the product and to know whether it has the optical rotation. At the same time, GPC was used to analyze the molecular of the polymerization products.. The research show that coniferin can polymerize with lignin model compound（β-O-4） into lignin macro- molecule,and the product does not have optical rotation also the molecule is much larger. So which can make the foundation for further studies that coniferin is used to the waste water processing.
