Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. 111-90-0, formula is C6H14O3, Name is Diethylene Glycol Monoethyl Ether. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3. Reference of 111-90-0.
Rahimpour, Elaheh;Acree, William E. Jr.;Jouyban, Abolghasem research published 《 Prediction of sulfonamides’ solubilities in the mixed solvents using solvation parameters》, the research content is summarized as follows. The exptl. solubility data of various sulfonamides in the binary solvent systems at various temperatures are collected from the literature and fitted to Jouyban-Acree model as an accurate cosolvency model for providing solubility prediction tools. In order to obtain predictive cosolvency models, the Jouyban-Acree model is combined with physicochem. parameters of the Abraham solvation parameters and the Hansen solubility parameters. Based on these computations, the generally trained versions of the combined models are proposed which enable one to predict the solubility of sulfonamides in the binary solvent mixtures at various temperatures with reasonable error levels.
Reference of 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.
