摘　　要：本文通过合成超支化聚酰胺-胺(HPAMAM)作为大分子骨架,使用棕榈酰氯接枝的方式对其进行改性,得到了具有疏水基团的超支化聚酰胺-胺(CPAMAM)。破乳实验结果表明,温度为60℃、沉降时间40min、添加量为120mg·L^(-1)时,CPAMAM比冀东油田目前所用聚醚型破乳剂的破乳效率高20%,且破乳速度更快。对CPAMAM的破乳机理分析结果证明,经过疏水化改性的CPAMAM可通过电荷吸附与大分子增溶剂作用对乳状液中油滴进行聚并,使CPAMAM具有更高的破乳效率。In this paper,hyperbranched polyamide-amine with hydrophobic groups(CPAMAM)was obtained by synthesizing hyperbranched polyamide-amine(HPAMAM)as a macromolecular backbone and modifying it by grafting palmitoyl chloride.The results of the demulsification experiment showed that the demulsification efficiency of CPAMAM was 20%higher than that of the polyether demulsifier currently used in Jidong Oilfield,with a temperature of 60℃,a sedimentation time of 40 min,and a dosage rate of 120mg·L^(-1).The results of the analysis of the demulsification mechanism of CPAMAM showed that the hydrophobic modified CPAMAM could polymerize the oil droplets in the emulsion through charge adsorption and macromolecular solubilization,so that CPAMAM had a higher demulsification efficiency.
