Use

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.
