Preparation method：

This compound can be synthesized through the reaction of diethyl alcohol with methanol or by reacting diethylene glycol monomethyl ether with chloromethane (or dimethyl sulfate).
For refining purposes, it is recommended first to treat the compound with granular sodium hydroxide to remove impurities. Subsequently, the purification process involves reflux and vacuum distillation in the presence of calcium hydride, lithium aluminum hydride, sodium borate, or sodium hydride. These operations are conducted in a nitrogen stream to maintain optimal conditions. To address any amine-like odor in diethylene glycol, DME can be effectively eliminated by shaking it with a weakly acidic ion exchange resin before drying and distillation. As an additional precaution, 0.01% sodium boride can be added during storage to prevent peroxide formation.
