Unsaturated Halogenated Hydrocarbons

The document detailed eleven unsaturated halogenated hydrocarbons, focusing on their uses, properties, and toxic effects. Dichloroacetylene was noted for its high toxicity and spontaneous combustibility, often resulting from trichloroethylene exposure in closed systems. Allyl chloride was handled with care due to its eye irritation effects. Hexachlorobutadiene was primarily an unwanted by-product in the U.S., with limited use as a chemical intermediate. β-Chloroprene exposure led to eye and respiratory irritation, liver injury, and hair loss. Vinyl chloride exposure, mainly through inhalation, was linked to liver cancer and other severe health effects, with metabolism playing a role in its toxicity. Trichloroethylene and perchloroethylene were widely used industrial solvents, with the former used in dry cleaning and metal degreasing, and the latter causing CNS depression at high concentrations.
