[8] At 400500C, a free radical halogenation occurs, converting these precursors to progressively more chlorinated compounds: Chloroform undergoes further chlorination to yield carbon tetrachloride (CCl4): The output of this process is a mixture of the four chloromethanes: chloromethane, dichloromethane, trichloromethane (chloroform), and tetrachloromethane (carbon tetrachloride). WebChloroform is also known as trichloromethane or methyltrichloride. It is a colorless liquid with a pleasant, nonirritating odor and a slightly sweet taste.

In 1865 as a direct result of the criminal reputation chloroform had gained, the medical journal The Lancet offered a "permanent scientific reputation" to anyone who could demonstrate "instantaneous insensibility", i.e. WebChloroform, or trichloromethane, is an organic compound with formula CHCl3. Soon, its popularity as an anesthetic soared to the point that it said that it was even used during the birth of Queen Victorias last two children in the 1850s. [16][36] CDCl3 is a common solvent used in NMR spectroscopy. Although we can measure the amount of chloroform in the air that you breathe out, and in blood, urine, and body tissues, we have no reliable test to determine how much chloroform you have been exposed to or whether you will experience any harmful health effects. Federal agencies that develop regulations for toxic substances include EPA, the Occupational Safety and Health Administration (OSHA), and the Food and Drug Administration (FDA). Some people used chloroform as a recreational drug or to attempt suicide. The Scottish obstetrician James Young Simpson was one of the persons required to read the thesis, but later claimed to have never read the thesis and to have come to his conclusions independently.
