DIPHENYLETHER Meaning and
Definition
-
Diphenylether is a chemical compound consisting of a central oxygen atom bonded to two phenyl groups. It is classified as an ether due to its structure, where an oxygen atom is sandwiched between two aromatic rings. The molecular formula of diphenylether is C12H10O.
Diphenylether is a colorless solid compound that has a characteristic sweet odor. It is insoluble in water but can dissolve in organic solvents such as ethanol and ether. It has a melting point of around 26-27 degrees Celsius and a boiling point of approximately 258-260 degrees Celsius.
This compound finds various applications in industrial and chemical processes. It can function as a high-temperature heat transfer fluid, contributing to its use in heat-transfer systems. Diphenylether also serves as a precursor for the synthesis of other organic compounds, including pharmaceuticals, dyes, and polymers.
From a health and safety perspective, diphenylether is considered to have low toxicity. However, it should still be handled with caution, as exposure to high concentrations or prolonged exposure may lead to eye and skin irritation. Inhalation of its vapors may cause respiratory discomfort.
In summary, diphenylether is a chemical compound with two phenyl groups linked by an oxygen atom. It is used as a heat transfer fluid and as a starting material for manufacturing various organic compounds. It is mainly characterized by its sweet odor, low solubility in water, and relatively low toxicity.
Etymology of DIPHENYLETHER
The word "diphenylether" is derived from a combination of three components: "di-", "phenyl-", and "ether".
The prefix "di-" indicates "two" or "double", suggesting that there are two of something in the compound.
"Phenyl-" refers to the aromatic group called phenyl, which is derived from benzene. A phenyl group consists of a six-carbon ring with five carbon atoms and one hydrogen atom bonded to it. In this case, there are two phenyl groups present.
The term "ether" is derived from the Old English word "aether", which means "upper air" or "sky". It also has roots in Greek mythology, where Aether was the personification of the atmosphere or the heavenly air. In chemistry, an ether is a functional group composed of an oxygen atom bonded to two alkyl or aryl groups.
