Product Name:Methylal
English Name:Methylal
CAS No.:109-87-5
Aliases:Formaldehyde dimethyl acetal, Dimethoxymethane, Methylene dimethyl ether
Molecular Formula:C3H8O2
Physical Properties:Colorless transparent liquid with a chloroform-like odor. Boiling point 42.3°C, melting point -104.8°C, flash point -17.8°C, auto-ignition temperature 237°C. Relative density 0.861 (20/20°C), saturated vapor pressure 43.99 kPa (20°C), explosion limit 1.6% to 17.6% (V/V). Soluble in water; miscible with alcohols, ethers, acetone, etc.; dissolves resins and oils with stronger solvency than diethyl ether and acetone.
Uses:Used as a solvent in cosmetics, pharmaceuticals, household products, industrial automotive products, insecticides, leather polishes, cleaning agents, rubber industry, paints, inks, and other products. With excellent degreasing ability and volatility, it can replace F11, F113, and chlorine-containing solvents, reducing VOC emissions as an environmentally friendly solvent. Also used in aerosol formulations to improve vapor pressure and atomization rate, and as an additive in paints, varnishes, adhesives, inks, and air fresheners.
