Inhalation Risk:A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20 °C.
Effects of Short Term Exposure:The substance is irritating to the eyes and respiratory tract. The substance may cause effects on the central nervous system. Exposure far above the OEL could cause unconsciousness.
Effects of Long Term Exposure:The substance defats the skin, which may cause dryness or cracking.
Physical properties Dimethoxymethane appears as a clear colorless liquid with a pungent, chloroform-like odor. Flash point 0°F. Boiling point 42.3°C. Density 0.864 g / cm3 at 68°F (20°C). Vapors heavier than air.
Uses Dimethoxymethane (Methylal) is a valuable extraction solvent for pharmaceutical products and a stable, inexpensive solvent for Grignard reactions. Methylal is stable under alkaline and mild acidic conditions. Its dissolving ability is stronger than ether, acetone, and methanol and azeotrope can dissolve nitrocellulose with high nitrogen content. Dimethoxymethane is mainly used in the production of anion-exchange resins, and also as solvents and special fuels.
