Product Usage: Methylal because of excellent physical and chemical properties, namely good solubility, low boiling point, good miscibility with water, with alcohol, ether, acetone, etc. immiscibility; soluble resin and oil, dissolving capacity than the ether, acetone strong; and methanol azeotrope high soluble nitrogen content of nitrocellulose; 16 ℃, when dissolved in water and 32.3% (WT); water methylal dissolved at 4.3% (WT). According to methylal dissolution characteristics, which can be used as part of hydrocarbon solvents, halogen substitutes; much solvent immiscible with good, especially with LPG, DME is better for Histoco***tibility and low boiling point, to improve the aerosol steam pressure and atomization rate is extremely favorable; methylal have excellent water solubility, for the development of water-based aerosol provides a good development prospects. Methylal can therefore widely used in cosmetics, pharmaceuticals, household good |
