使用红外光谱，我们已经表明，在水相中HCl的不同平衡浓度下，其磷酸三丁酯@acts含有：1）在CHcla < 2.3 M时，胶束状缔合物H5 O2+（H2O）n−2（TBP）mCl−·（H2O·TBP）2（n = 26和m = 13），讨论了胶束的结构。2）在2.3M < CHCla <5.6M时，胶束为二聚体缔合物[H5 O2+（H2O）2Cl−（H2O·TBP）2]2; 3）在5.6 M < CHCla < 8.5 M时，氢键分子碎片H5 O2+（TBP）2/3Cl−（A）; 4）在CHCla > 8.5 M时，大量的H3 O+反溶剂化物开始形成与最近邻分子氢键结合的分子碎片H3 O+（TBP）1/3Cl−（B）。在CHcla > 5.6 M时，几乎没有游离TBP分子出现在提取物中，并且由A片段形成结构化液体;在CHcla > 8.5 M时，由B片段形成结构化液体。
Using IR spectroscopy we have shown that at digerent equilibrium concentrations of HCl in aqueous phases, its tributyl phosphate @acts contain: 1) at CHcla < 2.3 M, micelle-like associates H5O2+(H2O)n−2(TBP)mCl−·(H20·TBP)2 (n ≈ 26 and m ≈ 13), the structure of micelles is discussed 2) at 2.3 M < CHCla < 5.6 M, dimer associates [H5O2+(H2O)2Cl−(H2O·TBP)2]2; 3) at 5.6 M < CHCla < 8.5 M, H-bonded molecular fragments H5O2+(TBP)2/3Cl−(A); and 4) at CHCla > 8.5 M, considerable amounts of the H3O+ tisolvate start to form in molecular fragments H3O+(TBP)1/3Cl−(B) H-bonded with the nearest neighbors. At CHcla > 5.6 M, almost no free TBP molecules occur in the extracts and a structured liquid forms from the A fragments; and at CHcla > 8.5 M, from the B fragments.
