Ethers are a class of organic compounds that contain an ether group—an oxygen atom connected to two alkyl or aryl groups. 111-90-0, formula is C6H14O3, Name is Diethylene Glycol Monoethyl Ether.They have the general formula R–O–R′, where R and R′ represent the alkyl or aryl groups. HPLC of Formula: 111-90-0.
Romdhani, Asma;Martinez, Fleming;Pena, Angeles;Rahimpour, Elaheh;Jouyban, Abolghasem;Acree, William E. Jr. research published 《 Solubility of trans-resveratrol in {ethanol (1) + water (2)} mixtures revisited: Correlation, dissolution thermodynamics and preferential solvation》, the research content is summarized as follows. Reported equilibrium mole fraction solubility values of trans-resveratrol in some aqueous-ethanolic mixtures in the temperature interval from (273.2 to 323.2) K were correlated by means of some cosolvency models, like multi-linear models of Jouyban-Acree and Jouyban-Acree-van’t Hoff and non-linear models of the modified Wilson and Buchowski-Ksiazczak. Apparent thermodn. functions of the dissolution processes were computed using the van’t Hoff and Gibbs equations. Gibbs energy and enthalpy were pos. in all cases, while neg. and pos. entropies were observed The plot of enthalpy vs.Gibbs energy of dissolution was non-linear with neg. slopes in the region of 0.00 ≤x1 ≤ 0.60 but pos. slope in the region of 0.60 ≤ x1 ≤ 0.90. Further, by means of the inverse Kirkwood-Buff integrals is observed that trans-resveratrol is preferentially solvated by water in water-rich mixtures but preferentially solvated by ethanol in the composition interval of 0.24 ≤ x1 ≤ 1.00.
HPLC of Formula: 111-90-0, Diethylene glycol monoethyl ether appears as a colorless, slightly viscous liquid with a mild pleasant odor. Flash point near 190°F. Used to make soaps, dyes, and other chemicals.
Diethylene glycol monoethyl ether is a primary alcohol that is ethanol substituted by a 2-ethoxyethoxy group at position 2. It has a role as a protic solvent. It is a diether, a primary alcohol and a hydroxypolyether. It derives from a diethylene glycol., 111-90-0.
