The chemical compound "Perchloroethylene", also known as "tetrachloroethylene", has a complex and lengthy spelling. It is pronounced /ˌpərˌklɔrəˌɛθiˈlin/, which can be broken down into individual phonemes. The first syllable "per" is pronounced with a short "e" sound, followed by the two syllables "chloro" and "ethylene" which are also pronounced separately. The second syllable "chloro" is pronounced with a "k" sound, and the final syllable "ethylene" is pronounced with a short "e" sound and a "th" sound. Overall, the spelling of "Perchloroethylene" reflects its complex and scientific nature.
Perchloroethylene, also known as tetrachloroethylene or PCE, is a chlorinated hydrocarbon compound commonly used as a solvent in dry cleaning processes and in various industrial applications. It is represented by the chemical formula C2Cl4.
As a solvent, perchloroethylene exhibits excellent dissolving properties and can effectively remove greases, oils, and other substances from fabrics, metals, and other materials. It is widely used in dry cleaning as it can dissolve a wide range of stains without damaging the fabric.
In addition to its use in dry cleaning, perchloroethylene finds application in industries such as metal degreasing, metal cleaning, and as a precursor in the production of fluorocarbons. It is also utilized as a heat transfer medium in certain industrial processes.
Perchloroethylene is a colorless liquid with a sweet odor. It is nonflammable and has a relatively high boiling point, making it suitable for various high-temperature applications. However, it may pose health and environmental risks if not handled properly. Prolonged exposure to perchloroethylene can lead to health issues such as skin irritation, dizziness, headaches, and even liver or kidney damage.
Due to its potential environmental concerns, efforts have been made to reduce the use of perchloroethylene and promote the use of alternative solvents in various applications.
The word Perchloroethylene is derived from its chemical structure and composition.
The term perchloro refers to the presence of chlorine (Cl) atoms bonded to a carbon (C) atom, forming a chlorinated hydrocarbon compound. Per in the term signifies multiple chlorine atoms attached to the carbon atom.
The second part of the word, ethylene, refers to the hydrocarbon compound ethene (also known as ethylene), which consists of two carbon atoms double-bonded to each other (C=C).
Therefore, perchloroethylene describes a compound with multiple chlorine atoms attached to a carbon atom, in addition to the presence of an ethylene group.
Perchloroethylene is also commonly known as tetrachloroethylene or perc.
