| 摘 要： | 以1，4-丁二醇为溶剂提取玉米芯中的木质素，考察了反应温度、原料／溶剂固液比（g/mL）、1，4-丁二醇的质量分数、反应时间等因素对木质素收率的影响。最佳萃取条件为：反应温度200℃，固液比（g／mL）1：10，1,4-丁二醇的质量分数90％，反应时间1h，以少量硫酸作为催化剂，木质素收率37．03％。红外光谱分析结果表明，1，4．T-醇提取的玉米芯木质素较好地保存了木质素原有结构。

| Abstract: | Lignin was extracted from corncob with aqueous solution of 1,4-butanediol as extracting reagent. The effects of temperature, the material/solvent solid-liquid ratio, the concentration of 1,4-butanediol and time on the yield of lignin were investigated. The optimal extracting condition was that extraction temperature 200℃, solid-liquid ratio （g/mL） 1 ： 10, 1,4-butanediol concentration （mass fraction） 90%, reaction time 1 h, and a small amount of sulfuric acid as catalyst. The results indicated that lignin mass yield was 37.03% by weight of corncob. The result of FTIR showed that the lignin from corncob using 1,4-butanediol kept the original structure. |
