应用
Ethylene glycol is used as a precursor for the syntheses of polymers like polyester fibers, resins and polyethylene terephthalate, which finds application in making plastic bottles. It acts as an intermediate in the synthesis of 1,4-dioxane. It plays an important role in organic synthesis as a protecting group for carbonyl groups. It is a useful desiccant due to its high boiling point and affinity towards water. It plays an important role to remove water vapor from natural gas before proceeding for further processes. Its major application is as a medium for convective heat transfer in automobiles and liquid cooled computers.
