Since the boiling point of water is lower than ethylene glycol, the use of evaporated water, when the lack of industry glycol coolant, just add water on the line. This antifreeze can be recycled after use (to prevent mixing of petroleum products), through sedimentation, filtration, water was added to adjust the concentration of small quantities of ethylene glycol industry, supplemented with preservative industry glycol GB enough content, but also continue to use, generally available 3--5 years. Many people think that a low freezing point of ethylene glycol, the freezing point of antifreeze is ethylene glycol and water mixed in different proportions according to a post and the freezing point, it is not true, due to changes in the mix after the cooling water vapor pressure, freezing point will significantly reduced. English name: Di-ethylene glycol, Ethylene diglycol referred DEG Chinese name: diethylene glycol, diethylene glycol ethers, diethylene glycol. Colorless hygroscopic viscous liquid, non-corrosive industrial glycol brake oil, raw materials, melting point -10.45 ℃ formula :: C4H10O3 Molecular Weight: 106.11 CAS Number: 111-46-6 EINECS Registry Number: 203-872-2 Relative density: 1.1164 (20 ℃) ??pure freezing point: -l0.45 ℃ Boiling point: 244.8 ℃ Melting point: -10.45 ℃ Solubility: with water, ethanol, acetone, ether, ethylene glycol, insoluble in benzene, toluene, carbon tetrachloride. Main purposes: as antifreeze, gas dehydration agents, plasticizers, solvents, etc. Also for the synthesis of unsaturated polyester resins. In the store in a cool, ventilated coffers, fire and moisture. Diethylene glycol and corresponding alcohol or alkyl halide as the raw material can be obtained diethylene glycol mono (double) ether, diethylene glycol mono (double) ether, widely used in inks, paints, resins, paints and dyes, etc. The solvent was also used as antifreeze additive synthesis of organic solvents and automotive fuels.
