Application
Diethylene glycol diethyl ether is a colorless liquid primarily used as a high-boiling solvent and reaction medium. This polyether, also known as 2-Ethoxyethyl ether, plays a crucial role in supporting various chemical processes. It serves as an organic solvent suitable for studying enzyme activities in water-organic mixtures and is ideal for high-temperature reactions. Additionally, it finds applications in the preparation of nitrocellulose, resins, and adhesives. In the petroleum industry, this compound acts as a scrubbing medium to effectively absorb impurities like carbonyl sulfide. Notably, it serves as an efficient absorbent for CO2 due to its rich philic-CO2 groups, which enhance capture capability. With a high boiling point, it allows for energy-efficient regeneration with minimal loss, alongside being chemically and thermally stable, non-corrosive, and possessing low density and viscosity. Research by Li et al. highlights that the presence of carbonyl and ether groups in such absorbents improves CO2 solubility, with the carbonyl group demonstrating greater effectiveness than the ether group.
