Glycol Preparation: Typically the metal is dissolved in the glycol, only monohydric alcohols; salts such as this alkoxides (e.g., sodium ethylene glycol) was heated to 180 ~ 200 ° C in a hydrogen content of ethylene GB stream may formation of disodium ethylene glycol and ethylene glycol. The use of ethylene glycol and heated with 2 moles of sodium methoxide, disodium ethylene glycol can be obtained. Disodium ethylene glycol is reacted with an alkyl halide to produce ethylene glycol monomethyl ether or diether. Disodium ethylene glycol is reacted with 1,2-dibromoethane to generate dioxane. In addition, ethylene is also easily oxidized, with the oxidizing agent or reaction conditions used in different kinds of products can be generated, such as glycolaldehyde HOCH2CHO, glyoxal OHCCHO, glycolic HOCH2COOH, HOOCCOOH acid and carbon dioxide and water. Of ethylene glycol and other diols different periodate oxidation can occur via a carbon strand breaks. Applications glycol instead of glycerin can often use various countries since the 1950s, almost all using ethylene glycol as antifreeze. Ethylene glycol is a colorless, transparent, slightly sweet and viscous liquid having a hygroscopicity, it is compatible with water in any proportion. The concentration of ethylene glycol is not the same. Freezing point is also different. Ethylene glycol - the freezing point of water with glycol antifreeze is not a linear relationship between the mass fraction. Freezing its solution is not entirely increases with the concentration decreases when the concentration of more than 70% ethylene glycol lowest prices, but increased the freezing point. In the preparation process of ethylene glycol solvent, from reality to be a reasonable choice to achieve frost resistance and economy requirements. In southern China, the general mass fraction of 40% ethylene glycol ratio, while in the cold north, need to take the mass fraction of about 50% ethylene glycol ratio is more appropriate.
