Glycol itself is relatively active substance, readily polymerized into polymers, the polymer is further oxidized to organic acids (commonly called sludge), the formation of a very sticky material, after deposition of scale easily; other glycol reacts with oxygen to produce a trace amount of formic acid and acetic acid. Most standard chemical structural formula of ethylene glycol HH | | HO-CC-OH | | HH described as follows: ethylene glycol (Ethylene Glycol, called EG), also known as glycol, ethylene glycol polyester grade ethylene glycol, the appearance of colorless clear viscous liquid formula C2H6O2, molecular weight of 62.07, freezing point -11.5 ℃, boiling point 197.6 ℃ professional suppliers of raw materials, the relative density of 1.1135 (20/4 ℃), refractive index 1.43063; soluble in water, lower alcohols, glycerin, acetone, acetic acid, pyridine, aldehydes, slightly soluble in ether, almost insoluble in benzene, carbon disulfide, chloroform and carbon tetrachloride. Ethylene glycol is an important petrochemical base of organic raw materials, mainly used in the production of polyester fibers, antifreeze, unsaturated polyester resins, lubricants, plasticizers, nonionic surfactants and explosives, but can also use coatings, photographic developer, brake fluid and ink and other industries, is used as a solvent and ammonium perborate medium for the production of special solvents and glycol ethers, uses a wide range of Guangzhou City Mong Road, Chemical Co., Ltd. is an industrial grade glycol manufacturers, mainly engaged in imported green glycol, polyester grade ethylene glycol oil level. Antifreeze is dedicated 99.9% high purity ethylene and other chemical raw materials. Professional production factory direct, spot ethylene supply stability, quality assurance; price advantage, the cash supply. Glycol: The main system for polyester-grade ethylene glycol Polyester much money, polyester resin, dehumidifying agents, plasticizers, surfactants, synthetic fibers, cosmetics and explosives, and as a solvent dye / ink, etc., formulated engine antifreeze, gas dehydration agent, producing resins, polyester glycol, antifreeze can also be used for cellophane, fiber, leather, adhesives humectant. When ethylene glycol is used as coolants should be noted that; 1, its freezing point with varying concentrations of ethylene glycol in the aqueous solution varies, concentrations of 59% or less, the concentration of ethylene glycol aqueous solution freezing point depression, but After the environmental concentrations in excess of 59% polyester grade ethylene glycol with concentration, its freezing point rise, when the concentration reaches 100% of its foreign-point rise to -13 ℃, which is concentrated antifreeze (antifreeze liquor) Why is one of the important reasons can not be directly used, you must draw the user's attention. 2. ethylene glycol containing hydroxyl, long-term work at 80 degrees C -90 degrees Celsius, easily oxidized to the acid water tank, leaving the water jacket leaks caused by corrosion. Therefore, in formulating antifreeze, it must also have a preservative to prevent the formation of iron and steel, aluminum, corrosion and scale.
