DIETHYLENE GLYCOL Meaning and
Definition
-
Diethylene glycol (DEG) is a colorless, odorless, and hygroscopic organic compound with the chemical formula C4H10O3. It is a diol, belonging to the family of glycols, and consists of two ethylene glycol (EG) units connected by an oxygen atom. DEG is highly soluble in water, alcohol, and ether.
Primarily, DEG is used as a solvent and a humectant, meaning it has the ability to attract and retain moisture. Due to its hygroscopic properties, it finds application in various industries and products. It is commonly utilized as a component in antifreeze, coolants, and deicing fluids, as it lowers the freezing point of water, thus preventing solidification in cold temperatures.
Moreover, DEG is employed as a solvent in the manufacture of dyes, resins, printing inks, and textiles. It also serves as a raw material in the production of polyester resins, which are widely used as adhesives, plastics, and paints. Additionally, DEG is found in some personal care products, such as creams, lotions, and toothpaste, where it functions as a moisturizing agent.
However, diethylene glycol should be handled with care, as it is considered toxic when ingested or inhaled. Ingestion of high doses can cause serious health issues, including kidney and liver damage. Therefore, it is crucial to comply with safety guidelines and regulations when handling or using diethylene glycol.
Etymology of DIETHYLENE GLYCOL
The word "diethylene glycol" derives from its chemical composition.
The term "glycol" originates from the Greek word "glýkys", meaning "sweet", since some glycols have a sweet taste. The suffix "-ol" indicates that it is an alcohol compound.
The term "ethylene" comes from the Greek word "ēthylēnē", which means "a colorless gas". Ethylene is a hydrocarbon compound consisting of two carbon atoms and four hydrogen atoms.
The prefix "di-" is derived from the Greek word "dis" or "di", which means "twice" or "two". In the context of "diethylene", it signifies that there are two ethylene groups present in the compound.
Thus, combining the components, "diethylene glycol" refers to a compound that consists of two ethylene groups bonded to a glycol structure.
