Chemische Eigenschaften
colourless liquid
Verwenden
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.
Allgemeine Beschreibung
A 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.
Air & Water Reaktionen
Highly flammable. Soluble in water.
Reaktivität anzeigen
DIETHOXYMETHANE, an acetal, is incompatible with strong oxidizing agents and acids. Breaks down to formaldehyde and ethanol in acidic solutions.
Health Hazard
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control may cause pollution.
Brandgefahr
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Sicherheitsprofil
Moderately toxic by
ingestion. Flammable when exposed to heat
or flame; can react vigorously with oxidizers.
When heated to decomposition it emits
acrid smoke and irritating fumes.
