摘要
采用天然植物油 (脱羧腰果壳液CNSL)作为疏水基的原料 ,经由己二异氰酸酯与亲水基聚乙二醇在较为温和的条件下反应 ,制得了两亲性表面活性剂 ,表征了其表面性能。该类表面活性剂的三个样品的临界胶束浓度为 0 .35～ 0 .5g/L ,亲油亲水平衡点为 15.5～ 16 .0 ,浊点为 70～ 80℃ ,临界胶束浓度下的表面张力 (2 5℃ )为 2 8～ 35mN/m。
A new kind of surfactant based on cashew nut shell liquid (CNSL) as lipophile group, HDI (hexame thylenediisocyanate) and polyethylglycol (as hydrophile group) was synthesized, and its surface properties was tested. Surface properties of three samples of this surfactant are: CMC 0.35～0.5 g/L; HLB 15.5～16.0; cloud point 70～80 ℃,surface tension (25 ℃, at CMC) 28～35 mN/m.
