詳細

詳細

Diethoxymethane (DEM) is a dialkoxymethane that can be synthesized by reacting ethanol and aqueous formaldehyde using macroporous cation-exchange resin Indion-130 as a catalyst. Infrared spectra of the conformers of DEM in various states have been obtained by matrix isolation infrared spectroscopy. The characteristic properties of DEM include low boiling point, low affinity for water, base stability and does not need drying for any reactions. Its infrared and Raman spectra have been reported.

アプリケーション

Diethoxymethane may be used as a substitute solvent to dichloromethane and toluene in the O-alkylation of different phenols in the presence of phase transfer catalysts (PTCs).
