马来酸壬基酚聚氧乙烯醚双酯HLB值的计算和验证

Calculation and Validation of HLB Value for Maleic Acid Nonyphenol Ethoxylates Diester Surfactant

通过多种方法计算了马来酸壬基酚聚氧乙烯醚正烷醇双酯的HLB值,并采用水数法进行了测定,对比分析了实验值与理论计算值。结果表明:马来酸壬基酚聚氧乙烯醚正烷醇双酯的HLB值可采用R值、溶解度参数以及Griffin公式来计算;对于用实验法难以测定其HLB值的马来酸壬基酚聚氧乙烯醚正烷醇双酯磺酸盐而言,其HLB值可采用R值来判断。

Hydrophile-lipophile balance（HLB） value of nonylphenol ethoxylate alkylalcohol maleate was calculated by the way of multiple methods in this paper.Experimental value was determined by the water number method.Theoretical value was compared by experimental value.The result suggests that it is more applicable to use R value,solubility parameter and the way of Griffin to calculate HLB value of nonylphenol ethoxylate alkylalcohol maleate.The experimental value of sodium nonylphenol ethoxylate alkylalcohol sufisuccinates could be estimated from R value.
