In the presented work, the stability of the formation of inclusion complexes of dodecanoic acid (lauric acid) with three cyclodextrins, α-cyclodextrin, β-cyclodextrin and 2-HP-β-cyclodextrin, was analyzed from the point of view of the size of the cavity in cyclodextrins, their molar mass and the structure of the studied fatty acid. The measurements were made in a wide temperature range of 283.15-318.15K. The conductometric method was used for these studies. The results obtained allowed us to determine the value of the theoretical limiting molar conductivity (Λm0) of the studied complexes, the values of the inclusion complex formation constants () and the values of thermodynamic functions (Δ, Δ and Δ) describing the complexation process in the studied temperature range.
在本工作中，从环糊精空腔大小、摩尔质量以及所研究脂肪酸结构的角度出发，分析了十二酸（月桂酸）与三种环糊精（α-环糊精、β-环糊精和 2-HP-β-环糊精）形成包合物的稳定性。测量在 283.15-318.15K 的较宽温度范围内进行。这些研究使用了电导率法。得到的结果允许我们确定所研究配合物的理论极限摩尔电导率（Λm0）的值、包合常数（）的值以及描述在所研究温度范围内配合过程的热力学函数（Δ、Δ和Δ）的值。
