Perchloroethylene ACS Grade: An In-depth Look




Perchloroethylene, commonly referred to as tetrachloroethylene, is a colorless, nonflammable liquid solvent with a somewhat sweet odor. When of ACS (American Chemical Society) grade, this chemical meets the stringent purity criteria set by the ACS and is suitable for lab applications that require high purity.


Physical and Chemical Properties


Molecular Formula: C2Cl4

Appearance: Clear, colorless liquid

Odor: Sweet, ether-like

Boiling Point: 121°C

Density: 1.622 g/cm3


Applications in the Laboratory


Perchloroethylene’s high purity in its ACS grade makes it a valued solvent in various laboratory applications:

  • Extraction: Due to its non-polar nature, it can be used to extract specific compounds from mixtures.
  • Organic Synthesis: Acts as a solvent in numerous organic reactions.
  • Instrument Cleaning: Its solvent properties make it ideal for cleaning laboratory equipment.


Handling and Storage


Due to its potential health hazards, it is essential to handle Perchloroethylene with care. The following are some general guidelines:

  1. Always use in a well-ventilated area or under a fume hood.
  2. Wear appropriate personal protective equipment, including gloves and safety goggles.
  3. Store in a cool, dry place away from open flames and incompatible substances.


Health and Safety


Exposure to Perchloroethylene can pose certain health risks. Inhalation of its vapors can lead to respiratory irritation, dizziness, and central nervous system depression. Chronic exposure might have more severe health effects. It’s imperative to have an MSDS (Material Safety Data Sheet) on hand and be familiar with its content when working with this solvent.


Environmental Concerns


Perchloroethylene is a chlorinated hydrocarbon, and its release to the environment can have detrimental effects, especially in aquatic systems. It is also a known ozone-depleting substance. As a result, its use and disposal must be conducted with care, adhering to local regulations and best practices.




Perchloroethylene ACS Grade offers the purity required for delicate laboratory applications. While it serves numerous purposes, it’s essential to handle and store it with care, ensuring the safety of both the user and the environment. Always stay informed and prepared when working with such chemicals.
