摘　　要：以风化煤中提取的黄腐酸为原料,进行季铵化反应制备阳离子表面活性剂。研究了投料比、反应温度、反应时间等对产品性能的影响。结果表明:黄腐酸阳离子表面活性剂合成的最佳工艺条件为黄腐酸、环氧丙基三甲基氯化铵质量比为2∶1,温度为60℃,反应时间3 h;在此条件下,黄腐酸季铵盐1%水溶液的表面张力为45.129mN/m,溶解百分比为99.3%,发泡性能具有明显改善。Using the fulvic acid which extracted from weathered coal as raw material,cationic surfactants are synthesized by quaternary amination. The effect of reaction time,temperature and feed ratio on the reaction performance are investigated. The result shows that the optimum synthesis conditions of cationic acid surfactant are as follows： fulvic acid ∶ epoxypropyltrimethl ammonium chloride（ mass ratio） is 2 ∶ 1,reaction temperature is 60 ℃ and reaction time is 3 h; the surface tension of the 1% aqueous solution of fulvic acid quaternary ammonium salts is 45. 129 mN /m,respectively; and the dissolved percentage is99. 3%,the foam performance is improved obviously.
