2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides. Application of 112-59-4

Liquid-liquid equilibria for the ternary system water + diethylene glycol monohexyl ether + 2-methyl-2-butanol was written by Chiou, Da-Ren;Chen, Li-Jen. And the article was included in Fluid Phase Equilibria in 2004.Application of 112-59-4 The following contents are mentioned in the article:

Liquid-liquid equilibrium compositions of the ternary system water + diethylene glycol monohexyl ether + 2-methyl-2-butanol were measured at 293.15, 303.15, and 313.15 K under atm. pressure. The exptl. equilibrium data were successfully correlated with the UNIQUAC model. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Application of 112-59-4).
