Infinite-dilution relative volatility (α∞i.water) was measured at 50° and 80° using a Rayleigh distillation apparatus for dilute solutions of propylene glycol Bu ether (PnB), propylene glycol Pr ether (PnP), and dipropylene glycol Bu ether (DPnB) dissolved in water and brine (3% NaCl). The data were analyzed to determine infinite-dilution activity coefficient (γ∞i,aqueous), Henry’s Law constant, partial molar enthalpy of mixing, and Setschenow constant Partition ratio (K) for extraction of PnP was also measured using 14 hydrophobic organic extraction solvents, including alcs., ketones, ethers, chlorinated hydrocarbons, aromatics, and aliphatics. An interpretation of mol. interactions in solution is given based on the anal. of activity coefficients, as a function of temperature and salt concentration General rules are proposed for the class of hydrogen-bonding organic compounds characterized by the presence of a lower critical solution temperature (LCST) in the organic + water phase diagram. The αi,water is likely to increase as the temperature increases for stripping volatile LCST-type hydrogen-bonding organics from dilute aqueous solution, provided the pure-component vapor pressure relative to water (pSATi/pSATwater) also increases or stays approx. the same. For extraction of LCST-type compounds from aqueous solution, K is likely to increase as the temperature increases, provided that the mutual solubility between phases is low. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Product Details of 112-59-4).
2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Product Details of 112-59-4
