Diglyme (CAS 111-96-6)

Diglyme is a versatile solvent known for its excellent solvating properties, particularly in both polar and non-polar solvent applications due to its ether and alcohol functional groups. Structurally, Diglyme consists of two ethylene glycol units connected by ether linkages with two terminal methyl groups, which contribute to its moderate boiling point and relatively low viscosity. In the realm of research, Diglyme is extensively utilized as a high-performance solvent in organic synthesis, where its ability to dissolve a wide range of reagents and catalysts is particularly valuable. This property facilitates various chemical reactions, including those sensitive to moisture and air. Additionally, Diglyme has been employed in the study of coordination chemistry to solvate metal ions without coordinating them, allowing researchers to isolate and study metal complexes in a relatively unaltered state. Another significant application of Diglyme is in the field of electrochemistry, where it is used as a solvent in electrolyte solutions for lithium batteries. Its robust solvating capabilities enhance the ionic conductivity of the electrolyte, thereby improving the efficiency and performance of the battery systems. Diglyme′s low toxicity compared to other glycol ethers also makes it a preferred choice in environments where safer chemical handling is prioritized.
