Dichloromethane uses

Dichloromethane StructureDichloromethane is a chemical compound that is also known as Methylene dichloride or Methyl chloride. Besides oceans, macro algae, volcanoes, and wetlands, it is also found in oceans and wetlands. Methylene dichloride is mostly released into the environment from industrial sources. Dichloromethane is chemically represented by CH2Cl2. The sweet, penetrating smell of ethylene chloride gives it a colourless, ether-like appearance. Hydrocarbons chlorinated by chlorination are volatile liquids. Despite being non-combustible, it can emit toxic chloride fumes if subjected to high temperatures. The fumes are narcotic at high concentrations. Solvents and paint removers are both commonly used in its manufacture. Uses • Food technology uses dichloromethane as a solvent. • In aerosol formulations, it is used as a solvent. • Dichloromethane is also used to blow foam. • Pharmaceutical products are manufactured using it as a solvent. • Pharmaceutical products are manufactured using it as a solvent. • A degreasing agent, CH2Cl2, is employed. • Electronics are manufactured with it. Tetrachloromethane StructureTetrahedral molecular geometries of carbon tetrachloride molecules contain four chlorine atoms linked together by the carbon atom in the center. Here is a diagram of the CCl4 molecule. UsesCarbon tetrachloride was routinely used to produce chlorofluorocarbons for refrigeration until the 1980s. Fire extinguishers and cleaning agents were also made with it. A nu...

Methylene chloride, also called dichloromethane (DCM), is a volatile, polar, organochloride compound that’s miscible with many organic solvents. A colorless liquid at room temperature, methylene chloride has a sweet, penetrating odor. It’s a member of the halomethanes or chloromethanes group where one or more hydrogens has been replaced by a halogen (chlorine). Though non-combustible and non-flammable, methylene chloride can emit toxic chloride fumes when exposed to high temperatures. The vapors are narcotic in high concentrations. Dichloromethane is formally rated as a probable carcinogen by IARC 2A and is a potentially toxic compound. It has been detected in feces, saliva, and other biofluids. Synonyms: Dichloromethane, methylene dichloride, methylene bichloride, DCM

The Frank R. Lautenberg Chemical Safety for the 21 st Century Act amends the EPA selected the first 10 chemicals to undergo risk evaluation under the amended TSCA and to make those understandable for the public, the American Council on Science and Health is producing risk-based evaluations of each, which will then be compiled into a free downloadable book for consumers. What is Dichloromethane (DCM) ? Methylene chloride, also known as dichloromethane (DCM), is a colorless liquid with a mild, sweet odor which evaporates easily but does not readily burn. It is widely used as an industrial solvent and as a paint stripper and can be found in certain aerosol and pesticide products and may also be found in some spray paints, automotive cleaners, and other household products. Methylene chloride is also used in the manufacture of photographic film. It is made from methane gas or wood alcohol, it does not occur naturally in the environment. The chemical structure of methylene chloride is very simple as shown at the US National Library of Medicine’s Toxnet database (NLM, 2018a). It is one of the simplest chlorinated hydrocarbons, made by substituting two chlorine atoms for two hydrogen atoms on the methane molecule (formula CH 2Cl 2). This simple structure and ability to be metabolized lead to its principle effect in experimental animals, that of liver and kidney toxicity at high levels of exposure (ATSDR, 2000). EPA (2011) indicates that the most common effect in humans is on neuro...

Introduction Dichloromethane, also commonly known as methylene dichloride, is a clear, colorless liquid at room temperature. It is volatile, and when it evaporates gives off a distinct odor that is sometimes characterized as being sweet or ether-like. Dichloromethane is categorized as a haloalkane, meaning that it is an alkane (a hydrocarbon with only single bonds), with halogen (group 17 element) substitution of some hydrogen atoms. It is specifically based upon the simplest of all the alkanes, methane, or CH 4, where two of the hydrogen atoms in that molecule are replaced by chlorine atoms. Methane, CH 4 Dichloromethane, CH 2Cl 2 Dichloromethane as a solvent By far the most popular application of dichloromethane is as a general Properties that make dichloromethane a good solvent choice Attributes that make DCM a good solvent include: • polarity (it has positive and negative parts that allow it to be attracted to some molecules), • relative inertness (it does not tend to react chemically with other substances that it comes into contact with) • miscibility with a very wide range of substances Another important property of dichloromethane related to its role as a solvent is its density. The chlorine atoms present in such compounds tend to create molecules that have higher densities than water, and dichloromethane is no exception. It has a density of around 1.33 g/mL, with water being around 1.00 g/mL (dependent upon temperature). This allows dichloromethane to form a separa...
