In 2023–2024, the leading exporters of Tetrachloroethylene (CAS 127-18-4) were the United States, Germany, and China, collectively accounting for over 55% of global exports by value; major importers included India, Mexico, and South Korea, driven by demand in dry cleaning and metal degreasing sectors. Trade volumes remained relatively stable year-on-year, though regional shifts emerged—India’s imports rose notably amid domestic industrial expansion, while Tetrachloroethylene prices edged upward modestly in response to tightening environmental regulations and raw material cost pressures.
Tetrachloroethylene (CAS 127-18-4) is a clear, colorless, volatile liquid with a characteristic chloroform-like odor; it has a boiling point of 121 °C and a melting point of −22 °C. It is classified as a chlorinated aliphatic hydrocarbon and a fully halogenated ethylene derivative. Primarily used as a nonflammable solvent, it serves in dry cleaning, metal degreasing, and vapor degreasing applications. It also functions as a chemical intermediate in the production of fluorocarbons, including hydrofluoroolefins (HFOs) such as 2-chloro-3,3,3-trifluoropropene (244a), and in the synthesis of refrigerants and specialty fluorochemicals. Its principal application areas include industrial cleaning, automotive and aerospace manufacturing, and fluoropolymer precursor synthesis.
Tetrachloroethylene (PCE) is also known as perchloroethylene, tetrachloroethene, and 1,1,2,2- tetrachloroethene and is also commonly abbreviated to PER or PERC. Tetrachloroethylene is a volatile, chlorinated organic hydrocarbon that is widely used as a solvent in the dry-cleaning and textile-processing industries and as an agent for degreasing metal parts. It is an environmental contaminant that has been detected in the air, groundwater, surface waters, and soil (NRC, 2010).
Tetrachloroethylene is a clear, colorless, volatile, nonflammable liquid with an ethereal odor. Insoluble in water. Vapors heavier than air. Density approximately 13.5 lb/gal. Used as dry cleaning solvent, a degreasing solvent, a drying agent for metals, and in the manufacture of other chemicals.
