Methylal has excellent physical and chemical properties, including good solubility, low boiling point, and good water solubility. It can be widely used in cosmetics, pharmaceuticals, household products, industrial automotive products, insecticides, leather polishing agents, cleaning agents, rubber industries, paints, inks, and other products. Due to its excellent oil removal ability and volatility, methylal can replace F11, F113, and chlorinated solvents as a cleaning agent. Therefore, it is an environmentally friendly product that replaces Freon, reduces volatile organic compound (VOC) emissions, and reduces air pollution.
