As a result of these properties it can act as a potential candidate for the halogen bonding and here the main focus of this study was to investigate the halogen bonding ability of different halogens (Cl2, Br2 and F2) and chlorofluorocarbons
with nitrobenzene theoretically.
Millions of tons of chlorofluorocarbons
(CFCs), human-made chemicals, spewed into the atmosphere in the 1970s and '80s from spray cans, refrigerators, and air conditioners.
Four major areas of continuing concern for BOMA are the enforcement of the Americans with Disabilities Act (ADA), the phaseout of chlorofluorocarbons
(CFCs), Indoor Air Quality (IAQ), and tax issues.
Hydrofluoroalkanes (HFAs) are propellants that will replace the chlorofluorocarbons
(CFCs) propellants that are harmful to the ozone layer.
The chemicals emitted include trace amounts of ozone-destroying chlorofluorocarbons
, perfluorocarboxylates (which accumulate in animal tissues), and trifluoroacetic acid (which has unknown effects on animals and humans).
Hydrofluorocarbon (HFC) refrigerants have enabled companies around the world to replace chlorofluorocarbons
(CFCs) & hydrochlorofluorocarbons (HCFCs).
Substances targeted include:- chlorofluorocarbons
(CFCs) 11, 12, 113, 114 and 115, and other fully-halogenated chlorofluorocarbons
intended for essential uses or for destruction- carbon tetrachloride intended for essential uses- 1,1,1-trichloroethane intended for essential uses- methyl bromide in applications other than quarantine and pre-shipment applications, in quarantine and pre-shipment applications, in laboratories or in essential uses- hydrochlorofluorocarbons (HCFCs) used for essential or critical uses or as process agents intended for regeneration or destruction, in laboratory work, in exempted uses and in other applications allowed by Article 5 of the Regulation.
Researchers have used green chemistry to develop alternatives to the use of gases, such as chlorofluorocarbons
, that can strongly contribute to Earth's warming.
the first speaker, presented a series of charts which explained the current replacement for different chlorofluorocarbons
(CFCs) used in air conditioning equipment.
This treaty stipulated that the production and consumption of compounds that deplete ozone in the stratosphere, including chlorofluorocarbons
(CFCs) and other harmful chemicals, was to be phased out by 2000.
Volcanoes belch an impressive array of organic chemicals into the air, but ozone-depleting chlorofluorocarbons
(CFCs) are an insignificant part of that mix, a new study finds.
Years before the media turned its cameras on stories about the dangers of electromagnetic radiation, the presence of lead in water and paint, indoor air quality and chlorofluorocarbons
(CFCs), professional property managers began educating themselves about the issues.
