응용 분야 · 2건

용도Diethoxymethane (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.

일반 설명A colorless volatile liquid with an agreeable odor. Less dense than water. Flash point below 10°F. Vapors heavier than air. May be narcotic in high concentrations. Used as a solvent and in the manufacture of cosmetics.
