摘　　要：由烷基酚聚氧乙烯醚和甲醛缩合合成了Gemini非离子表面活性剂——由亚甲基相联的烷基酚聚氧乙烯醚。通过测试,证明其具有比原料烷基酚聚氧乙烯醚较高的表面活性、较高的去污能力、较低的泡沫性和较低的浊点。这些性能使得它们具有高效、低温和宜于机洗的洗涤性能。A Gemini nonionic surfactant-methylene-jointed polyethoxylated alkylphenol ether was synthesized by condensation of polyethoxylated phenol ether and formaldehyde. It was proved that it had higher surface activity, better detergency, lower foam property, and lower cloud point than polyethoxylated alkylphenol ether. These positive properties made the said Gemini surfactants potential materials for high detergency, favorite for washing at low temperature, and for machine washing.
