DIETHOXYMETHANE Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

General Description

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 Reactions

Highly flammable. Soluble in water.

Reactivity Profile

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.

Fire Hazard

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.
