As chloroform is a volatile organic compound, [18] it dissipates readily from soil and surface water and undergoes degradation in air to produce phosgene, dichloromethane, formyl chloride, carbon monoxide, carbon dioxide, and hydrogen chloride. Its half-life in air ranges from 55 to 620 days. Biodegradation in water and soil is slow.
Chloroform. Chloroform (also called trichloromethane) is a chemical substance. It is an organic compound. Chloroform is one of the intermediate substances that occur in the production of Polytetrafluoroethylene, better known as Teflon. Chloroform is used as a solvent. It is a colourless liquid.
chloroform (CHCl3), nonflammable, clear, colourless liquid that is denser than water and has a pleasant etherlike odour. It was first prepared in 1831. The Scottish physician Sir James Simpson of the University of Edinburgh was the first to use it as an anesthetic in 1847. It later captured public notice in 1853 when English physician John Snow ...
Military Use of Ether and Chloroform. American military doctors began using ether as an anesthetic on the battlefield during the Mexican-American War (1846-1848), and by 1849 it was officially ...

Chloroform (systematische Bezeichnung Trichlormethan) ist ein chlorierter Kohlenwasserstoff mit der Summenformel CHCl 3. Formal ist es das Trichlorid der Orthoameisensäure, woraus sich der Name herleitet. In der Industrie dient es als Lösungsmittel und zur Herstellung von Fluorchlorkohlenwasserstoffen. Seit der Mitte des 19.
The feasibility of an oxygen-independent mechanism of chloroform bioactivation was indicated by the covalent binding to lipid and protein occurring in anaerobic incubations of chloroform and microsomes in the presence of NADPH. Under these conditions, the loss of cytochrome p450 and the inhibition of related mono-oxygenases were also observed.
Chloroform (CHCl 3) is a solvent, reagent, refrigerant, and anesthetic with a chemical history that dates back to the 1830s. During that period, at least five scientists synthesized it; but there was much confusion about its chemical formula. Proposed formulas ranged from CH 2 ClCH 2 Cl (“chloric ether” or 1,2-dichloroethane) to C 2 Cl 5 ...
Chemical Formula: CHCl3. Melting Point: -63 C. Boiling Point: 61 C. Density: 1.489 g/mL. Chloroform (CHCl3) is a relatively common organic solvent. In most organic chemistry labs, however, methylene chloride is used as a substitute. Deuterated chloroform (CDCl3) is one of the most common NMR solvents.
Chloroform. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Trichloromethane, or chloroform, is a chemical compound with the formula CHCl3. It is one of many examples of a haloalkane, and is often used as a nonpolar solvent in organic chemistry.
Deuterated chloroform, also known as chloroform- d, is the organic compound with the formula CDCl3. Deuterated chloroform is a common solvent used in NMR spectroscopy. [2] The properties of CDCl3 and ordinary CHCl3 (chloroform) are virtually identical. Deuterochloroform was first made in 1935 during the years of research on deuterium.
Chloroform. Chloroform, or trichloromethane (often abbreviated as TCM), is an organochloride with the formula C H Cl 3 and a common solvent. It is a volatile, colorless, sweet-smelling, dense liquid produced on a large scale as a precursor to refrigerants and PTFE. Chloroform was once used as an inhalational anesthetic between the 19th century ...
Eigenschappen. Chloroform heeft een zoetige geur en smaak, en een bedwelmende werking. Hoofdpijn, slaperigheid en bewusteloosheid zijn de gevolgen van het inademen van de damp. Hiervoor is meer nodig dan één of twee teugen. Chloroform is dan ook ongeschikt om iemand bij verrassing te bedwelmen, zoals in sommige films wordt gesuggereerd.
Chloroform, or trichloromethane, is an organic compound with formula CHCl3. It is a colorless, strong-smelling, dense liquid that is produced on a large scale as a precursor to PTFE. It is also a precursor to various refrigerants. It is one of the four chloromethanes and a trihalomethane. It is a powerful anesthetic, euphoriant, anxiolytic and sedative when inhaled or ingested. The molecule ...
chloroform (uncountable) (organic chemistry) A halogenated hydrocarbon, trichloromethane, CHCl 3; it is a volatile, sweet-smelling liquid, used extensively as a solvent and formerly as an anesthetic.

Chloroform may also refer to: "Chloroform" (song), a song by Phoenix. "Chloroform", a song by Crystal Castles from Amnesty (I) "Chloroform", a song by SycAmour.
Chloroform, hay còn gọi là trichloromethan và methyl trichloride, và một hợp chất hoá học thuộc nhóm trihalomethan có công thức C H Cl 3. Nó không cháy trong không khí, trừ khi tạo thành hỗn hợp với các chất dễ bắt cháy hơn.
Chloroform neboli trichlormethan (mimo chemii dle PČP trichlormetan), je bezbarvá těkavá, avšak nehořlavá kapalina charakteristického nasládlého zápachu. Jeho páry jsou značně těžší než vzduch (4,12krát), proto se v uzavřených prostorách hromadí u podlahy a obtížně se vyvětrává.
Trihalomethane. In chemistry, trihalomethanes (THM s) are chemical compounds in which three of the four hydrogen atoms of methane (CH4) are replaced by halogen atoms. Trihalomethanes with all the same halogen atoms are called haloforms. Many trihalomethanes find uses in industry as solvents or refrigerants.
Chloroform is in 1831 deur drie navorsers onafhanklik van mekaar ontdek: Die eerste aanwending was in die analgesie. Die Fransman Marie Jean Pierre Flourens het in 1847 hierdie aanwending op diere gemeld, maar die Skot James Young Simpson (1811–1870) het dit reeds in 1846 op mense geprobeer. In 1853 het selfs koningin Victoria by die geboorte ...
