화학적 성질
colourless liquid with a camphor-like smell.Pentachloroethane is incompatible and very reactive in contact with sodium potassium (alloy + bromoform), alkalis, metals, and water. On hydrolysis, pentachloroethane produces dichloroacetic acid and the reaction with alkalis and metals produces chloroacetylenes, which becomes spontaneously explosive. Pentachloroethane is a colourless stable liquid with a camphor-like smell and non-flammable. Pentachloroethane is incompatible with strong oxidising agents and reacts violently with alkalis or metals.

용도
용도
Pentachloroethane has been used as a solvent and chemical intermediate but has had little commercial utilization. Pentachloroethane is used as a solvent for oil and grease in metal cleaning; in the separation of cola from impurities by density difference; as a chemical intermediate in the manufacture of tetrachloroethylene and dichloroacetic acid; as a solvent for cellulose acetate, certain cellulose ethers, resins, and gums; as a drying agent for timber by immersion at temperatures greater than 100C; in dry cleaning and soil sterilizing.
일반 설명
A colorless liquid with a chloroform-like odor. Insoluble in water and denser than water. Toxic by inhalation and ingestion. May irritate skin and eyes. Used as a solvent.
