Ethylene glycol Use

Mainly used in the production of polyester resins, alkyd resins, plasticizers, antifreezes, and also used in cosmetics and explosives; used as analytical reagents, chromatographic analysis reagents and capacitor media; ethylene glycol is the fungicide tebuconazole and moxa The intermediate of the spirit. Gas chromatographic stationary liquid (maximum use temperature 50 ℃ , solvent is chloroform), separation and analysis of low-boiling oxygen-containing compounds, amine compounds, nitrogen or oxygen heterocyclic compounds. Determination of calcium oxide in cement, solvents, antifreeze, manufacture of polyester resins, plasticizers, cosmetics, explosives, cold-resistant lubricants, surfactants, varnishes, dyes, inks, etc., organic synthesis.
