Exptl. evidence of corresponding states in water, n-alkane (CκH2κ+2), and n-alkyl polyethylene glycol ether (CiEj) systems is presented. Striking similarities in both the phase behavior and the interfacial tensions for a variety of systems are highlighted. For some selected systems the trajectories f the middle phases in the three-phase regime are precisely determined Projections of the middle-phase trajectories onto the ϕc-ϕ plane of the phase prism shape nearly perfect parabolae, whereas the projections onto the T-ϕ plane exhibit a sigmoidal shape. Here ϕc is the surfactant volume fraction, and ϕ is the oil-in-water-plus-oil volume fraction. It is found that the trajectories collapse into single curves, if the surfactant concentration scale is reduced by the maximum of the parabolae, ϕ̅c, which is the surfactant volume fraction of the sym. microemulsion, and if the temperature axis is reduced by the difference of the upper and lower critical endpoint temperature, Tu-Tl. It is found that the maximum length scale ξ̅ α ϕ̅c-1 set by the surfactant volume fraction can be used to reduce the interfacial tension scale, that is plotting σabϕ̅c-2 vs. the reduced temperature scale. These reductions yield a remarkable superposition of the interfacial tension data of 17 different systems, the carbon number of the oil κ ranging from 8 to 14, the hydrophilic surfactant head j from 3 to 6 and the surfactant tail length i from 8 to 12. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4HPLC of Formula: 112-59-4).
2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
