DIETHOXYMETHANE CAS 462-95-3

DIETHOXYMETHANE Basic information

    Diethoxymethane (DEM) is offered by Eastman Chemical Company as a cost-effective replacement solvent for monoglyme (1,2- dimethoxyethane) and methylal.  The DEM diether is stable under alkaline conditions, but can be cleaved by strong acids.   Diethoxymethane can be used as a chemical intermediate in many organic synthesis reactions.

    Diethoxymethane is useful as a solvent in lithium batteries with nonaqueous electrolytes, as a solvent for polymeric materials, and as a fuel additive.   As a chemical intermediate DEM can act as an ethoxymethylating reagent for alcohols and phenols and serve as a source for formaldehyde in organic synthesis.
