| 摘 要： | 以褐煤腐植酸、Na2SO3、NaOH为原料对褐煤腐植酸进行磺化改性；采用电导法对其磺化度进行测定；通过考察固液比、反应时间、反应温度对磺化腐植酸磺化度的影响获得最佳工艺参数：磺化剂与腐植酸钠溶液的液固比2：20、磺化温度50℃、磺化时间90min；产品磺化度为17．7％；红外光谱表明，磺化腐植酸中磺酸基团明显增多，确实发生了磺化反应。

| Abstract: | The lignite humic acid was Sulfonated using Na2SO3 as sulfonating agent . The sulfonation degree weredeter- mined by conductance method. The best process parameters were obtained through experiment. It were researched that effect of humic acid- sulfonating agent ratio, reaction time. temperature on acid sulfonation degree. The results show that sulfonating agent and Na2SO3 solution ratio 2 ： 20, sulfonation temperature 50℃, reaction time 90min, the sulfonation degree is 17.7%. The infrared spectra show that sulfonic acid groups increased significantly in the sulfonated humic acid, it shows that the sulfonation reaction does occur. |
