Ethylene glycol is an organic compound primarily used as a raw material in the manufacture of polyester fibers and fabric industry, and polyethylene terephthalate resins (PET) used in bottling. A small percent is also used in industrial applications like antifreeze formulations and other industrial products. It is an odorless, colorless, syrupy, sweet-tasting liquid. Ethylene glycol is only weakly toxic, but cases of poisonings are not uncommon.
Ethylene glycol is a chemical commonly used in many commercial and industrial applications including antifreeze and coolant. Ethylene glycol helps keep your car’s engine from freezing in the winter and acts as a coolant to reduce overheating in the summer. Other important uses of ethylene glycol include heat transfer fluids used as industrial coolants for gas compressors, heating, ventilating, and air-conditioning systems, and ice skating rinks.
Ethylene glycol also is used as a raw material in the production of a wide range of products including polyester fibers for clothes, upholstery, carpet and pillows; fiberglass used in products such as jet skis, bathtubs, and bowling balls; and polyethylene terephthalate resin used in packaging film and bottles. Many of these products are energy saving and cost efficient as well as recyclable.
Ethylene glycol breaks down in air in about ten days, and in water or soil in a few weeks. It enters the environment through the disposal of ethylene glycol-containing products, especially at airports where it is used in deicing agents for runways and airplanes. It has been linked as a teratogen in certain species of birds.
IUPAC name: ethane-1,2-diol
CAS Registry Number:107-21-1
Appearance:clear viscous liquid
Density:1.220 g/mL at 25°C
Stability:Stable at room temperature in closed containers under normal storage and handling conditions.
Usage:Automotive antifreeze, solvent, adjuvant.
Chemical Properties:clear viscous liquid
Usage:Reagent typically used in cyclocondensation reactions with aldehydes1 and ketones1,2 to form 1,3-dioxolanes.
General Description:Ethylene glycol is a clear, colorless syrupy liquid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since Ethylene glycol is a liquid Ethylene glycol can easily penetrate the soil and contaminate groundwater and nearby streams.
Reactivity Profile:Mixing Ethylene glycol in equal molar portions with any of the following substances in a closed container caused the temperature and pressure to increase: chlorosulfonic acid, oleum, sulfuric acid.
Health Hazard:Inhalation of vapor is not hazardous. Ingestion causes stupor or coma, sometimes leading to fatal kidney injury.
Fire Hazard:Ethylene glycol is combustible.
