摘　　要：制备了不同碳链长度的二元环氧化合物 ,并使其与聚合度为 8～ 9的聚氧乙烯 (PEO)或 SPAN80反应 ,合成了含有不同长度间隔链的双亲水基表面活性剂。用傅立叶红外光谱仪和核磁共振仪对其结构进行了表征。实验结果表明 ,具有疏水性间隔链的双亲水基表面活性剂具有良好的表面活性 ,其表面活性不仅比单亲水基表面活性剂的大 ,且可随着疏水间隔链长度的增加而增大。A series of surfactants with double end hydrophilic groups and different chain spacers were synthesized by reacting compounds containing two end epoxy groups and different long carbon chains with poly(ethylene oxide)(PEO, M w=400) or SPAN80. The surfactants were characterized by FTIR and 1H NMR. It was shown that the activity of the surfactant with two end hydrophilic groups and a lipophilic spacer is better than that of which has only one hydrophilic group, and the activity was increased with the length of the lipophilic spacer.
