Dichloromethane melting point

Dichloromethane is principally used as a solvent in paint removers and as an aerosol propellant. It is used as a blowing and cleaning agent in the production of urethane foam and plastic fabrication and in paint stripping operations.

It is used in metal cleaning, as a solvent in the production of polycarbonate resins, in film processing, and in ink formulations. Dichloromethane is used in the food industry as an extraction solvent for spices, caffeine decaffeinated coffeeand hops.

Dichloromethane's use in aerosol products includes paints and automotive spray products. Dichloromethane is an organic solvent that is clear and colourless and has a mild sweet odour. It is a volatile liquid that is, it evaporates quickly. Dichloromethane can affect you if breathed in and by passing through the skin. Exposure to high concentrations may cause unconsciousness and death.

Exposure may irritate the lungs, which can cause a build up of fluid pulmonary oedema. Lower doses may cause headaches, fatigue, and behaviour similar to being drunk. Dichloromethane exposure may cause the heart to beat irregularly or stop. Long term exposures at high levels may damage the liver and brain. The International Agency for Research on Cancer classifies dichloromethane as a 'possible human carcinogen'.

Worksafe Australia categorises dichloromethane into Category 3, a 'suspected human carcinogen'. It is possible that there is no safe level of exposure to a carcinogen.

Dichloromethane will enter the body if we breathe in contaminated air. It can also pass through the skin. Workers in the industries that use or produce dichloromethane are at risk of exposure. Consumers can be exposed to dichloromethane by exposure to air from production and processing facilities using dichloromethane.

Consumers may also be exposed to dichloromethane when using consumer products containing dichloromethane, especially if there is not good ventilation. Note above the large number of consumer products containing dichloromethane. Safe Work Australia sets the workplace exposure standard for dichloromethane through the workplace exposure standards for airborne contaminants :.

It is also known to the scientists under the names methylene chloride or methylene dichloride. It naturally occurs in oceans, volcanoes, wetlands, and macroalgae, but mainly appears as the result of industrial processes.

Dichloromethane is a colorless liquid with a moderately sweet, chloroform-like aroma. It is highly volatile and emits toxic fumes when heated. The chemical has no definite flash point, though it forms flammable vapor-air mixtures. It is fully miscible with carbon tetrachloride, ethyl acetatechloroform, alcohol, benzenediethyl ether and hexanes. Here are some more properties of dichloromethane:.

Most hazards of dichloromethane are connected with human health. The substance is extremely toxic. It can seriously irritate eyes, nose and throat, harm nervous system and even be fatal. DCM is proven to be animal carcinogen, and in case of prolonged exposure can cause cancer to humans. Most of the dichloromethane uses are connected with its solvent properties. In household, it serves as a component of paint and varnish strippers.

Besides, the DCM is often used in bathtub refinishing. The chemical is widely applied in industry and manufacturing. It is an important extraction solvent in beverage and food production.

For example, it dichloromethane is used to remove caffeine from coffee beans and tea leaves, to process spices, to create hops extract for beers, etc. In transportation industry, the substance is present in lubricating and degreasing products, to clean metal parts and surfaces quickly and safely.

Furthermore, the DCM is used in the manufacture of synthetic fibers, photographic films, inks, and many others.

Ethanol Acetic Acid. Properties and Hazards Dichloromethane is a colorless liquid with a moderately sweet, chloroform-like aroma.

Here are some more properties of dichloromethane: Boiling point: Uses of Dichloromethane Most of the dichloromethane uses are connected with its solvent properties. Name Text Repeat code.This colorless, volatile liquid with a moderately sweet aroma is widely used as a solvent.

Although it is not miscible with water, it is polarand miscible with many organic solvents. Natural sources of dichloromethane include oceanic sources, macroalgaewetlands, and volcanoes. At these temperatures, both methane and chloromethane undergo a series of reactions producing progressively more chlorinated products.

In this way, an estimatedtons were produced in the US, Europe, and Japan in The output of these processes is a mixture of chloromethane, dichloromethane, chloroformand carbon tetrachloride as well as hydrogen chloride as a byproduct. These compounds are separated by distillation. DCM was first prepared in by the French chemist Henri Victor Regnault —who isolated it from a mixture of chloromethane and chlorine that had been exposed to sunlight. DCM's volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes.

The chemical compound's low boiling point allows the chemical to function in a heat engine that can extract mechanical energy from small temperature differences.

An example of a DCM heat engine is the drinking bird. The toy works at room temperature. DCM chemically welds certain plastics. For example, it is used to seal the casing of electric meters. Often sold as a main component of plastic welding adhesivesit is also used extensively by model building hobbyists for joining plastic components together.

It is commonly referred to as "Di-clo. It is used in the garment printing industry for removal of heat-sealed garment transfers, and its volatility is exploited in novelty items: bubble lights and jukebox displays. DCM is used in the material testing field of civil engineering ; specifically it is used during the testing of bituminous materials as a solvent to separate the binder from the aggregate of an asphalt or macadam to allow the testing of the materials.

Even though DCM is the least toxic of the simple chlorohydrocarbonsit has serious health risks. Its high volatility makes it an acute inhalation hazard.C Cl Cl Copy Copied.

Chloromethane is an abundant organohalogenanthropogenic or natural, in the atmosphere. Laboratory cultures of marine phytoplankton Phaeodactylum tricornutumPhaeocystis sp. The salt marsh plant Batis maritima contains the enzyme methyl chloride transferase that catalyzes the synthesis of CH 3 Cl from S-adenosine-L-methionine and chloride.

In the sugarcane industry, the organic waste is usually burned in the power cogeneration process. When contaminated by chloride, this waste burns, releasing methyl chloride in the atmosphere. Chloromethane was first synthesized by the French chemists Jean-Baptiste Dumas and Eugene Peligot in by boiling a mixture of methanolsulfuric acidand sodium chloride.

This method is similar to that used today. Chloromethane is produced commercially by treating methanol with hydrogen chlorideaccording to the chemical equation : [5]. A smaller amount of chloromethane is produced by treating a mixture of methane with chlorine at elevated temperatures.

This method, however, also produces more highly chlorinated compounds such as dichloromethanechloroformand carbon tetrachloride. For this reason, methane chlorination is usually only practiced when these other products are also desired. This chlorination method also cogenerates hydrogen chloride, which poses a disposal problem.

Most of the methyl chloride present in the environment ends up being released to the atmosphere. After being released into the air, the life of this substance in the atmosphere varies from one to three years.

On the other hand, when the methyl chloride emitted is released to water, it will be rapidly lost by volatilization.

The [half-life] of this substance in terms of volatilization in the river, lagoon and lake is 2. Large scale use of chloromethane is for the production of dimethyldichlorosilane and related organosilicon compounds.

Dimethyldichlorosilane Me 2 SiCl 2 is of particular value precursor to siliconesbut trimethylsilyl chloride Me 3 SiCl and methyltrichlorosilane MeSiCl 3 are also valuable.

Smaller quantities are used as a solvent in the manufacture of butyl rubber and in petroleum refining. Chloromethane is employed as a methylating and chlorinating agent, e.
