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. SDS of cas: 111-90-0.
Rezaei, Hadis;Rezaei, Homa;Rahimpour, Elaheh;Martinez, Fleming;Zhao, Hongkun;Jouyban, Abolghasem research published 《 Solubility profile of phenytoin in the mixture of carbitol and water at different temperatures》, the research content is summarized as follows. In this study, solubility profile of phenytoin in carbitol and water mixtures at 298.2-313.2 K is measured and some linear and non-linear cosolvency models are used to numerical representation of these data. The prediction capability of used models is investigated using training the models with min. possible data. The accuracy of applied models is checked by the calculation of the mean relative deviations (MRD %). Apparent thermodn. dissolution quantities were calculated based on van’t Hoff and Gibbs equations observing pos. Gibbs energies and enthalpies but neg. entropies. Addnl., phenytoin is preferentially solvated by water in water-rich mixtures but preferentially solvated by carbitol in the interval 0.12 < × 1 < 0.85 based on IKBI method.
SDS of cas: 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.
