Some important polyhalogen compounds: Polyhalogen compounds: Carbon compounds containing more than one halogen atom permolecule. Dichloromethane (Methylene chloride) p,p'-Dichlorodiphenyl- trichloroethane (DDT) Trichloromethane (Chloroform) Polyhalogen Compounds Freons Triiodomethane (Iodoform) Tetrachloromethane (Carbon tetrachloride)

Process solvent in the manufacture of drugs 4. Metal cleaning and finishing solvent Harmful effects: 1. It endangers the human central nervous system. 2. Exposure to lower levels of methylene chloride in air can lead to slightly impaired hearing andvision. 3. High levels of methylene chloride in air cause dizziness, nausea, tingling and numbness in thefingers and toes. 4. In humans, direct skin contact with methylene chloride causes intense burning and mild rednessof the skin. 5. Direct contact with the eyes can burn the cornea. Trichloromethane (Chloroform) Uses: 1. Chemically, chloroform is used as a solvent for fats, alkaloids, iodine and other substances. 2. The major use of chloroform today is in the production of the freon refrigerant R-22.
