Dimethoxymethane CAS 109-87-5

Dimethoxymethane Basic information

    Dimethoxymethane, also called methylal, is a colorless flammable liquid with a low boiling point, low viscosity and excellent dissolving power. It differs from other ethers in that it forms only minute omounts of peroxides.  It will dissolve such synthetic resins as nitrocellulose, cellulose acetate and propionate, ethyl cellulose, vinyl, "Epons" and polystyrene, and also many of the natural gums and waxes.  Methylal as a latent solvent is activated by the addition of esters, ketones or alcohols.  Its evaporation rate, twice that of acetone, places this ether in a class with such solvents as acetone, methyl acetate and ethyl acetate in resin formulations.

    Dimethoxymethane is a versatile chemical with applications in many industries such as paints, perfume, resins, pharmacy, paint strippers, protective coatings, and fuel Additives.
1. It may be used in the synthesis of methoxymethyl (MOM) ethers.
2. It may also be used as an external cross-linker to form microporous polymers.
3. Reaction solvent or an extraction solvent manufacturing pharmaceuticals, aerosols, paints, varnishes and cleanings.
4. Production of ion exchange resins, polyacetal as a chain length regulator.
5. Glue Formulations fragrances and pesticides.
6. Fuel Additive for smoke reduction.
7. Blowing agent for PU Foams.
