一般描述
1,2-二甲氧基乙烷（DME）是一种惰性非质子极性溶剂，用于锂电池、聚有机硅、低聚物和多糖的电解质。
应用
1,2-二甲氧基乙烷可作为溶剂合成：
- 恶唑，通过 Robinson-Gabriel 反应从α-酰基胺酮中得到。
- 5-芳基组氨酸，通过 5-溴组氨酸和芳基硼酸之间的 Suzuki-Miyaura 交联。
- 芳基硫醚，通过 Pd-催化芳基卤化物与脂肪和芳香硫醇的硫醚化反应。

Glymes (i.e. glycol diethers) were explored as alternative benign solvents for enzymatic reactions, specifically the lipase-catalyzed transesterification. Long-chain glymes were found highly compatible with immobilized Candida antarctica lipase B (iCALB), leading to higher enzyme activities and stabilities than t-butanol and

The physical content of and, in particular, the nonlinear contributions from the Langevin-Debye model are illustrated using two applications. First, we provide an improvement in the Langevin-Debye model currently used in some implicit solvent models for computer simulations of solvation
