摘要
采用水数法,选择异丙醇/甲苯和1,4-二氧六环/苯两种溶剂体系测定了不同碳链长度和不同EO链长度的脂肪醇聚氧乙烯醚的HLB值。通过多项式方程拟合以及与文献计算值比较,确定1,4-二氧六环/苯是测定脂肪醇聚氧乙烯醚HLB值的比较好的溶剂系统。
HLB values of AEO with different EO chains and carbon chains were determined by water counting methods. By comparing the measured HLB values with the corresponding calculated HLB values from the references, we draw a conclusion that 1,4-dioxane/benzene solvent is more excellent＇ solvent system for AEO surfactants HLB analysis.
