摘　　要：研究了以丙烯酸改性松香为原料合成新型丙烯酸改性松香双季胺盐型阳离子表面活性剂的工艺,测定了它们的理化性质和表面性能,诸如含水量、含N量、阳离子活性物含量、Krafft点、表面张力、乳化力、泡沫力及泡沫稳定性等,表明它们具有良好的表面活性,并对其进行了红外光谱表征。Bi-quaternary ammonium cationic surfactants were synthesized from acrylic modified rosin. Their physical and facial properties,such as the amount of water and nitrogen,krafft point, surface tension,emulsifying ability,foaming ability were determined. The results showed that they possess good surface activity. FT-IR spectra of the product were also discussed.
