Dichloroethene or dichloroethylene, often abbreviated as DCE, can refer to any one of several isomeric forms of the organochloride with the molecular formula C2H2Cl2:
There are three isomers:
In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space. This contrasts with structural isomers, which share the same molecular formula, but the bond connections or their order differs. By definition, molecules that are stereoisomers of each other represent the same structural isomer.
DCE may refer to:
Tetrachloroethylene, also known under the systematic name tetrachloroethene, or perchloroethylene, and abbreviations such as "perc" (or "PERC"), and "PCE", is a chlorocarbon with the formula Cl2C=CCl2. It is a colorless liquid widely used for dry cleaning of fabrics, hence it is sometimes called "dry-cleaning fluid". It also has its uses as an effective automotive brake cleaner. It has a sweet odor, similar to the smell of chloroform, detectable by most people at a concentration of 1 part per million (1 ppm). Worldwide production was about 1 million metric tons (980,000 long tons; 1,100,000 short tons) in 1985.
The organic compound 1,1,1-trichloroethane, also known as methyl chloroform, is a chloroalkane with the chemical formula CH3CCl3. It is an isomer of 1,1,2-trichloroethane. This colorless, sweet-smelling liquid was once produced industrially in large quantities for use as a solvent. It is regulated by the Montreal Protocol as an ozone-depleting substance and its use is being rapidly phased out.
Dichloroethane can refer to either of two isomeric organochlorides with the molecular formula C2H4Cl2:
1,1-Dichloroethane is a chlorinated hydrocarbon. It is a colorless oily liquid with a chloroform-like odor. It is not easily soluble in water, but miscible with most organic solvents.
An electron acceptor is a chemical entity that accepts electrons transferred to it from another compound. It is an oxidizing agent that, by virtue of its accepting electrons, is itself reduced in the process. Electron acceptors are sometimes mistakenly called electron receptors.
1,2-Dichloroethene, commonly called 1,2-dichloroethylene or 1,2-DCE, is the name for a pair of organochlorine compounds with the molecular formula C2H2Cl2. They are both colorless liquids with a sweet odor. It can exist as either of two geometric isomers, cis-1,2-dichloroethene or trans-1,2-dichloroethene, but is often used as a mixture of the two. They have modest solubility in water. These compounds have some applications as a degreasing solvent. In contrast to most cis-trans compounds, the Z isomer (cis) is more stable than the E isomer (trans) by 0.4 kcal/mol.
1,2-DCE may refer to:
1,1-Dichloroethene, commonly called 1,1-dichloroethylene or vinylidene chloride or 1,1-DCE, is an organochloride with the molecular formula C2H2Cl2. It is a colorless liquid with a sharp odor. Like most chlorocarbons, it is poorly soluble in water, but soluble in organic solvents. 1,1-DCE was the precursor to the original clingwrap, Saran, for food, but this application has been phased out.
1,1-DCE may refer to:
Hendon is a north-western suburb of Adelaide, South Australia, 9.8 km from the Adelaide city centre. It is located in the City of Charles Sturt.
Difluoroethene or Difluoroethylene can refer to any one of several isomeric forms of the organochloride with the molecular formula C2H2F2:
In chemistry, vinylidenes are compounds with the functional group C=CH2. An example is 1,1-dichloroethene (CCl2=CH2) commonly called vinylidene chloride. It and vinylidene fluoride are precursors to commercially useful polymers.
Marinobacter salsuginis is a Gram-negative and moderately halophilic bacterium from the genus of Marinobacter which has been isolated from seawater from the Shaban Deep from the Red Sea. The strain BS2 of Marinobacter salsuginis can reduce the mortality of the shrimps Penaeus monodon and Litopenaeus vannamei by killing the dinoflagellate Noctiluca scintillans. The strain 5N-3 can degrade 1,2-Dichloroethene (cis-DCE) in the absence of inducing substrates like phenol.[6]
Sharkey Landfill is a 90-acre property located in New Jersey along the Rockaway and Whippany rivers in Parsippany, New Jersey. Landfill operations began in 1945, and continued until September 1972, when large amounts of toluene, benzene, chloroform, dichloroethylene, and methylene chloride were found, all of which have are a hazard to human health causing cancer and organ failure. Sharkey Landfill was put on the National Priority List in 1983, and clean up operations ran until the site was deemed as not a threat in 2004.
The Orange Valley Regional Groundwater Superfund site is a group of wells in Orange and West Orange, two municipalities in Essex County, New Jersey, United States. The groundwater in the public wells are contaminated with the hazardous chemicals of Trichloroethylene (TCE), Dichloroethene (DCE), Tetrachloroethylene (Perchloroethene), 1,1-Dichloroethene (1,1-DCE), and 1,2-Dichloroethene (1,2-DCE). These chemicals pose a huge risk to the towns nearby population, as the wells are a source of public drinking water. In March 2012, the site was added to the National Priorities List (NPL) of the United States Environmental Protection Agency (EPA) Superfund site list.
Lawrence Aviation Industries, Inc. was an aircraft parts manufacturer that made titanium parts for military aircraft, such as the Grumman F-14 fighter jet. The former owner of the company, Gerald Cohen, was sentenced to one year and a day in prison and ordered to pay $105,816 in restitution for illegally storing more than 12 tons of hazardous waste on the company's grounds. The former site of the company, in the hamlet of Port Jefferson Station, Town of Brookhaven, New York, is one of the most contaminated sites on Long Island and may be responsible for a toxic groundwater plume in the region. The site is bounded by the Long Island Railroad tracks and Sheep Pasture Road to the north. A Long Island Power Authority easement runs along the southern edge of the property, separating the site from a residential area. To the east and west are residential areas.
The K & L Avenue Landfill, also known by the spelling K&L Avenue Landfill, is an 87-acre (35-hectare) Superfund site accessed from KL Avenue in Oshtemo Township, Kalamazoo County, Michigan. It is one of six Superfund sites in the Kalamazoo River watershed.
Thermo-Chem, Inc., also referred to as Thermo-Chem, is a 50-acre Superfund site located in Egelston Township near Muskegon, Michigan.
