ETHYLENE GLYCOLS Meaning and
Definition
-
Ethylene glycols, also known as ethanediols, are a class of organic compounds that belong to the alcohol family. They are characterized as colorless, viscous liquids that possess a mildly sweet taste. The term "ethylene glycols" refers to a group of compounds consisting of two hydroxyl (-OH) groups attached to a central carbon atom.
The most prominent and widely used compound in this class is ethylene glycol (EG), which is the main constituent of antifreeze solutions. Ethylene glycol is an essential component in various industrial processes and products, including polyester fibers, polyethylene terephthalate (PET) resins, and automotive coolants. Another common compound falling under this classification is propylene glycol (PG), which shares similar chemical properties and applications with ethylene glycol but has a lower toxicity level.
Ethylene glycols have excellent stability, low volatility, and good solvency properties. Due to their hygroscopic nature, they readily absorb moisture from the atmosphere. They are miscible in water and many organic solvents. Additionally, ethylene glycols have a relatively low freezing point, which makes them ideal for applications requiring low-temperature stability.
Ethylene glycols exhibit moderate toxicity and should be handled with caution. Ingesting or inhaling these compounds can have harmful effects on living organisms, including both acute and chronic health hazards. Therefore, appropriate safety measures should be taken when using ethylene glycols, such as wearing protective gloves and masks, and ensuring proper ventilation.
Overall, ethylene glycols are versatile compounds widely utilized in various industries due to their unique properties and broad applications.

Etymology of ETHYLENE GLYCOLS
The word "ethylene" is derived from the Greek words "ethylos" meaning "pure" and "hylos" meaning "wood". It was originally used to describe a colorless gas with a sweet odor that is produced by heating ethyl alcohol with sulfuric acid and was originally obtained from the distillation of wood. "Glycols", on the other hand, refers to a class of chemical compounds with two hydroxyl (OH) groups attached to different carbon atoms. The term "glycol" is derived from the Greek word "glykys" meaning "sweet" and "holos" meaning "wholeness". This is due to the sweet taste of some of the compounds in this class. Therefore, "ethylene glycols" refers to glycols that are derived from ethylene.
