The physical properties of ethylene glycol: freezing point: -12.6 ℃ Boiling point: 197.3 ℃ density: the relative density (water = 1) 1.1155 (20 ℃); the relative density (Air = 1) 2.14 Appearance: colorless, sweet, viscous liquid vapor pressure: 0.06mmHg (0.06 mm Hg) / 20 ℃ Flash point: 111.1 ℃ Viscosity: 25.66mPa.s (16 ℃) [1] Solubility: water / ethanol / acetone / acetic acid mixed with glycerin pyridine glycol solvents, ether-soluble and insoluble in petroleum hydrocarbons and oils glycol polyester resin, capable of dissolving calcium / zinc chloride / sodium / potassium / chloride / potassium iodide / potassium hydroxide inorganic materials such as ethylene glycol: the number of hydroxyl groups in the molecule according to the manufacturers glycol, the alcohol can be divided into monohydric alcohols, diols and polyols. In the diols, referred to two hydroxyl vicinal diol glycol even paint on adjacent carbon atoms, and two hydroxyl groups even called Cellular diol on the same carbon atom. Quasi-diol is a general term referring to ethylene glycol, propylene glycol and other glycols.
