The highest effectiveness of detergency for nonionic surfactants is observed in the proximity of the cloud point. This phenomenon is primarily influenced by surfactant molecular structure, such as carbon chain length and type of the hydrophilic components. Target of this investigation is to identify a relationship between the cloud point and the structure of nonionic surfactants based on ethoxylated (C_nE_m), ethoxylated-propoxylated (C_nE_mP_p) and propoxylated-ethoxylated (C_nP_pE_m) fatty alcohols. Three hundred and fifty nonionic surfactants have been prepared for this purpose. These surfactants differ in the C-chain lengths, C₄/C₆ to C₂₀/C₂₂, and the amount of ethylene oxide (EO range [n] 2–22 ethoxylation) and propylene oxide (PO range [p] 0–12 propoxylation) moieties. Mapping the differences in the performance allows us to propose a high-accuracy topological model describing the structure influence on the cloud point.

预测烷氧基化非离子表面活性剂的浊点

在浊点附近观察到非离子表面活性剂的最高去污效果。这种现象主要受表面活性剂分子结构的影响，例如碳链长度和亲水组分的类型。本研究的目标是确定浊点与基于乙氧基化 (C _n E _m )、乙氧基化-丙氧基化 (C _n E _m P _p ) 和丙氧基化-乙氧基化 (C _n P _p E ) 的非离子表面活性剂结构之间的关系_m ) 脂肪醇。为此已制备了三百五十种非离子表面活性剂。这些表面活性剂的 C 链长度不同，C₄ /C ₆至 C ₂₀ /C ₂₂，以及环氧乙烷（EO 范围 [n] 2-22 乙氧基化）和环氧丙烷（PO 范围 [p] 0-12 丙氧基化）部分的量。映射性能差异使我们能够提出一个描述结构对浊点影响的高精度拓扑模型。
