Industrially, chloroform is produced by heating a mixture of chlorine and either methyl chloride (CH3Cl) or methane (CH4). At 400–500 °C, a free radical halogenation occurs, converting these precursors to progressively more chlorinated compounds: CH4 + Cl2 → CH3Cl + HCl CH3Cl + Cl2 → CH2Cl2 + … See more Chloroform, or trichloromethane (often abbreviated as TCM), is an organic compound with the formula CHCl3 and a common organic solvent. It is a very volatile, colorless, strong-smelling, dense liquid produced on … See more The molecule adopts a tetrahedral molecular geometry with C3v symmetry. The chloroform molecule can be viewed as a methane molecule with three hydrogen atoms replaced with three chlorine atoms, leaving a single hydrogen atom. See more Chloroform was synthesized independently by several investigators circa 1831: • Moldenhawer, a German pharmacist from Frankfurt an der Oder, appears to have produced chloroform in 1830 by mixing chlorinated lime See more Exposure Chloroform is known to form as a by-product of water chlorination, along with a range of other See more The total global flux of chloroform through the environment is approximately 660000 tonnes per year, and about 90% of emissions are natural in origin. Many kinds of seaweed produce chloroform, and fungi are believed to produce chloroform in soil. Abiotic processes … See more In terms of scale, the most important reaction of chloroform is with hydrogen fluoride to give monochlorodifluoromethane CHCl3 + 2HF → CHClF2 + 2 HCl The reaction is … See more Some anaerobic bacteria use chloroform for their respiration, termed organohalide respiration, converting it to dichloromethane. See more WebBoth oxidative and reductive pathways of chloroform metabolism have been described, although data in vivo are limited. Carbon dioxide is the major metabolite of chloroform generated by the oxidative pathway of metabolism in vivo. The oxidative pathway also generates reactive metabolites, ...

WebChloroform (CF) is largely produced by both anthropogenic and natural sources. It is detected in ground and surface water sources and it represents the most abundant halocarbon in the atmosphere. Microbial CF degradation occurs under both aerobic and anaerobic conditions. WebChloroform (CF), or trichloromethane, is an ubiquitous environmental pollutant because of its widespread industrial use, historically poor disposal and recalcitrance to biodegradation. Chloroform is a potent inhibitor of metabolism and no known organism uses it as a growth substrate. We discovered that CF was rapidly and sustainably ...
