摘　　要：用三甲胺和烯丙基氯合成了季铵盐小阳离子粘土稳定剂,通过测定不同条件下的合成率筛选出最佳合成条件:最佳反应时间为6h,最佳反应温度为55℃,三甲胺和烯丙基氯的最佳投料比为1∶1·6,产率可达89·8%。试验表明,相比其他粘土稳定剂,三甲基烯丙基氯化铵具有更好的粘土膨胀抑制性能。A mini-cationic clay stabilizer was synthesized by reaction of trimethylamine and allyl chloride.The optimum synthetic condiaions were determined by measuring production rate under different conditions.The best reaction time is 6 hours, the optimum reaction temperature is 55 ℃, the best ratio of trimethylamine and allyl chloride is 1∶1.6.Evaluation results show that compared with other clay stabilizing agent, the three-allyl chloride is better clay inhibition, and it becomes better and better with the concentration increase.
