Exempel på hur man kan använda BIPHENYL i en mening

• Polychlorinated biphenyl, an organic chlorine compound, now recognized as an environmental toxin and classified as a persistent organic pollutant.
• In 1973, a polybrominated biphenyl (PBB) contamination event caused farmers in the area to destroy their herds.
• From 1955 to the mid-1970s, an 11-acre portion of the site along the shore of Narragansett Bay, McAllister Point Landfill, accepted wastes consisting of acids, solvents, paint, waste oil, and oil contaminated with polychlorinated biphenyl.
• In a speech opposing the placement of hazardous polychlorinated biphenyl (PCB) waste in the Warren County, North Carolina landfill, Chavis defined the term as:

  racial discrimination in environmental policy making, the enforcement of regulations and laws, the deliberate targeting of communities of color for toxic waste facilities, the official sanctioning of the life-threatening presence of poisons and pollutants in our communities, and the history of excluding people of color from leadership of the ecology movements.

• The borabenzene-pyridine adduct behaves like a diene, not an analog of biphenyl, and will undergo Diels-Alder reactions.
• Polychlorinated biphenyl (PCB) and polyaromatic hydrocarbons (PAH) were found in low amounts in creek and marsh sediments.
• Polybrominated biphenyls (PBBs), also called brominated biphenyls or polybromobiphenyls, are a group of manufactured chemicals that consist of polyhalogenated derivatives of a biphenyl core.
• The column converts benzyl chloride to bibenzyl in a Wurtz coupling and in a similar fashion dibenzothiophene is reduced to biphenyl.
• The molecule has an extended biphenyl group with a tetrazole which is being used in place of the carboxylic acid as a bioisostere.
• The molecule structure resembles to that of two gallic acid molecules being assembled "head to tail" and bound together by a C–C bond (as in biphenyl, or in diphenic acid) and two lactone links (cyclic carboxylic esters).
• A recent area of work has been the destruction of toxic organic compounds by irradiation; after irradiation, "dioxins" (polychlorodibenzo-p-dioxins) are dechlorinated in the same way as PCBs can be converted to biphenyl and inorganic chloride.
• 5-megawatt (thermal) organically cooled and moderated nuclear reactor (terphenyl, a biphenyl like oil).
• A study observing Northern cricket frogs in environments contaminated with organochlorides concluded that sites contaminated with point polychlorinated biphenyl (PCB) and polychlorinated dibenzofuran (PCDF) were significantly related to sex-ratio reversal: contaminated sites had more males compared to control ponds, suggesting that organochlorines can influence cricket frog sexual differentiation.
• The first group of 20 congeners consists of those with chlorine substitution at none of the ortho positions on the biphenyl backbone and are referred to as CP0 or non-ortho congeners.
• In the very early years, ACAs were made from rubber, acrylic, and other adhesive compounds, but they rapidly converged on several different variations of thermoset biphenyl type epoxy resins.
• Fenbufen can be synthesized by acylation of biphenyl with succinic anhydride under Friedel-Crafts conditions.
• Products listed in the EEP Catalogue must comply with hazardous substance restriction limits for lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE), unless they fall into the Exemptions List.
• Friedel-Crafts acylation between biphenyl (1) and benzoyl chloride (2) gives 4-phenylbenzophenone (3).
• Pd-Catalyzed amination of dibromobiphenyls in the synthesis of macrocycles comprising two biphenyl and two polyamine moieties.
• This enzyme participates in 8 metabolic pathways: phenylalanine metabolism, benzoate degradation via hydroxylation, biphenyl degradation, toluene and xylene degradation, 1,4-dichlorobenzene degradation, fluorene degradation, carbazole degradation, and styrene degradation.
