Ethylene Glycol

Properties:

1. Chemical Stability: Industrial grade ethylene glycol is chemically stable and does not decompose easily.
2. Solubility: It is highly soluble in water and many organic solvents.
3. Boiling Point: It has a high boiling point, which is around 197.3°C (387.1°F).
4. Freezing Point: It has a low freezing point, which can be depressed further when mixed with water, making it useful as an antifreeze.
5. Heat Capacity: It has a high heat capacity, allowing it to absorb and release a significant amount of heat.

Uses:

1. Antifreeze: It is widely used in automotive and industrial applications as an antifreeze in cooling systems to prevent freezing and corrosion.
2. Hydraulic Fluids: Due to its high viscosity index and low pour point, it is used in hydraulic systems.
3. Heat Transfer Fluids: Its high heat capacity makes it suitable for use in heat exchange systems and as a coolant in various industrial processes.
4. De-Icing Agent: In aviation, it is used as a de-icing agent for aircraft surfaces.
5. Textile Industry: It is used in the textile industry as a solvent for dyes and in the production of polyester fibers.
6. Manufacture of Resins: It is used in the production of unsaturated polyester resins, which are used in the manufacturing of fiberglass and other composite materials.
7. Pharmaceutical Industry: It is used as a solvent in the pharmaceutical industry for the production of certain drugs and as a humectant in cosmetics.
8. Windshield Washer Fluid: It is a component in the formulation of windshield washer fluids for vehicles.
