The interfacial tensions between water- and oil-rich phases in the presence of microemulsions have been measured for ternary systems of water, n-alkanes, and nonionic alkylpolyglycolether surfactants (CiEj). It is found that the min. of the interfacial tension curve, which is observed for each system in conjunction with the well-known phenomenon of phase inversion, depends sensitively, but systematically, on the chem. nature of the oil and the surfactant. Specifically, the min. value of the interfacial tension σ̅ab decreases by 1 order of magnitude on decreasing either the carbon number of the alkane k by 6, or the number of oxyethylene groups j by 3, or by increasing the number of carbon atoms in the surfactant tail i by 2. The numerical values of the interfacial tensions as a function of temperature are presented along with an empirical description previously suggested. From the anal., in terms of bending energy one obtains estimates for the bending and saddle-splay constants The similar shape of the interfacial tension curves permits a superposition of the data for all 19 systems in support of a scaling relation recently derived (Leitao, S. et al., 1996). Furthermore, we note a striking coincidence of the numerical values of critical amplitude ratio R = σ0ξ02 = 0.37 kT in near-critical systems and the product σ̅abξ̅2 = 0.44(±0.10) kT where ξ̅ is the maximum length scale in the bicontinuous microemulsions. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Recommanded Product: 2-(2-(Hexyloxy)ethoxy)ethanol).
2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Recommanded Product: 2-(2-(Hexyloxy)ethoxy)ethanol
