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., Product Details of C6H14O3

Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. 111-90-0, formula is C6H14O3, Name is Diethylene Glycol Monoethyl Ether. Ethers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. Product Details of C6H14O3.

Osorio, Irmis P.;Martinez, Fleming;Pena, Maria A.;Jouyban, Abolghasem;Acree, William E. Jr research published 《 Extended Hildebrand solubility approach applied to sulphadiazine in aqueous binary mixtures of Carbitol and N-methyl-2-pyrrolidone at 313.15 K》, the research content is summarized as follows. Extended Hildebrand Solubility Approach (EHSA) was applied in this research to analyze the equilibrium solubility of sulphadiazine in some {N-methyl-2-pyrrolidone (1) + water (2)} and {Carbitol (1) + water (2)} mixtures at 313.15 K. Reported exptl. solubilities and melting properties of this drug were used for EHSA calculations Good predictive character of EHSA (with mean deviations lower than 1.7%) was found by using regular polynomials in order five by correlating the interaction parameter (W) and the Hildebrand solubility parameter of solvent mixtures free of drug (δ1+2). However, the predictive character of EHSA was almost the same as obtained when logarithmic drug solubilities (log x3) were correlated with δ1+2 by using a fifth-degree regular polynomial.
