Ethers do have nonbonding electron pairs on their oxygen atoms, 111-90-0, formula is C6H14O3, Name is Diethylene Glycol Monoethyl Ether. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds. Reference of 111-90-0.
Kataoka, Taishi;Orita, Yasuhiko;Shimoyama, Yusuke research published 《 CO2 absorption and desorption using phase-separation gel》, the research content is summarized as follows. Phase-separation absorbent has attracted much attention to reduce energy consumption for CO2 capture, storage and utilization. In this work, to improve handling of the absorbents, we have developed a new semi-solid absorbent, phase-separation gel, which became clouded gel by CO2 absorption and returned to transparent by CO2 desorption. We measured amounts of CO2 absorption at 50 C and desorption at 90 C with 10 vol% CO2 gas mixed with N2 gas. A cyclic capacity defined by the CO2 desorption amount of a phase-separation gel with solvent of 2-(ethylamino)ethanol/diethylene glycol di-Et ether was larger than those of the other homogeneous gels with 2-(ethylamino)ethanol/diethylene glycol monoethyl ether or diethylene glycol. Furthermore, the initial desorption flux of the phase-separation gel was larger than that of the absorbent solvent, suggesting that the phase-separation absorbent fixed inside the gels improves the initial desorption flux because of the larger interfacial area between the CO2-rich and CO2-lean phases inside the gel.
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., Reference of 111-90-0
