Bromoform is known as an inhibitor of methanogenesis and is a common component of seaweed. Following research by CSIRO and its spin-off FutureFeed , several companies are now growing seaweed, in particular from the genus Asparagopsis , to use as a feed additive for livestock to reduce methane emissions from ruminants .
The EPA limits the total concentration of the four chief constituents (chloroform, bromoform, bromodichloromethane, and dibromochloromethane), referred to as total trihalomethanes (TTHM), to 80 parts per billion in treated water. [6] Traces of chloroform are produced in swimming pools. [7] [8] [9] [10]
A bottle of bromoform, a heavy liquid. Uses. Common applications of heavy liquids include: Density gradient centrifugation; Separating mixtures and sink/swim analysis;
In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX 3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH 3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base.
In geology, a heavy mineral is a mineral with a density that is greater than 2.9 g/cm 3, most commonly referring to dense components of siliciclastic sediments. A heavy mineral suite is the relative percentages of heavy minerals in a stone.
Prior to the introduction of this chromium-based protocol, olefination reactions generally gave Z alkenes or mixtures of isomers. [1] Similar olefination reactions had been performed using a variety of reagents such as zinc and lead chloride; [5] however, these olefination reactions often lead to the formation of diols—the McMurry reaction—rather than the methylenation or alkylidenation of ...
Bromoform, produced by several algae, is a known toxin, though the small amounts present in edible algae do not appear to pose human harm. [12] Some of these organobromine compounds are employed in a form of interspecies "chemical warfare".
The mechanism for addition of a carbene to an alkene is a concerted [2+1] cycloaddition (see figure). Carbenes derived from chloroform or bromoform can be used to add CX 2 to an alkene to give a dihalocyclopropane, while the Simmons–Smith reagent adds CH 2. [10]
