Dichloromethane (DCM; Methylene Chloride) (CAS: 75-09-2) is a transparent, colorless, volatile halogenated aliphatic hydrocarbon compound with an ether-like mildly sweet smell. It is slightly soluble in water, soluble in ethanol and ether, and is a non-flammable low-boiling solvent under normal use conditions. When its vapor becomes high concentration in high-temperature air, it will generate a weakly combustible mixed gas, which is often used to replace Flammable petroleum ether, ether, etc.
Dichloromethane (DCM; Methylene Chloride) (CAS: 75-09-2), Used as an intermediate in organic synthesis. Widely used in pharmaceuticals, and cosmetics, process solvent, paint, surfaces degreasing agent, extracting agent, electrical engineering industry, plastics processing, and other industries.
Dichloromethane is used as a mobile phase in High Performance Liquid Chromatography and Liquid Chromatography coupled with Mass Spectrometry.
House Hold Uses
The compound is used in bathtub refurbishing. Dichloromethane is highly used industrially in the production of pharmaceuticals, strippers, and process solvents.
Industrial and Manufacturing Uses
DCM is a solvent that is found in varnish and paint strippers, which are often used to remove varnish or paint coatings from various surfaces. As a solvent in the pharmaceutical industry, DCM is used for the preparation of cephalosporin and ampicillin.
Food and Beverage Manufacturing
It is also used in manufacturing beverage and food manufacturing as an extraction solvent. For instance, DCM can be used to decaffeinate unroasted coffee beans as well as tea leaves. The compound is also used in creating hops extract for beer, beverages and other flavoring for foods, as well as in processing spices.
Transportation Industry
DCM is normally used in the degreasing of metal parts and surfaces, such as railroad equipment and tracks as well as airplane components. It can also be used in degreasing and lubricating products utilized in automotive products, for instance, removal of the gasket and for preparing metal parts for a new gasket.
Experts in automotive commonly use vapor dichloromethane degreasing process to for the removal of grease and oils from car parts of car transistor, spacecraft assemblies, aircraft components, and diesel motors. Today, specialists are able to safely and quickly clean transportation systems using degreasing techniques that depend on methylene chloride.
Medical Industry
Dichloromethane is used in laboratories in the extraction of chemicals from foods or plants for medicines such as antibiotics, steroids, and vitamins. In addition, medical equipment can be efficiently and quickly cleaned using dichloromethane cleaners while avoiding damage to heat-sensitive parts and corrosion problems.
Photographic Films
Methylene chloride is used as a solvent in the production of cellulose triacetate (CTA), which is applied in the creation of safety films in photography. When dissolved in DCM, CTA begins to evaporate as the fibre of acetate remains behind.
Electronic Industry
Methylene chloride is used in the production of printed circuit boards in the electronic industry. DCM is utilized to degrease the foil surface of the substrate before the photoresist layer is added to the board.
Dichloromethane (DCM; Methylene Chloride) (CAS: 75-09-2) reacts violently in the presence of alkali or alkaline earth metals and will hydrolyze to formaldehyde in the presence of an aqueous base. Alkylation reactions occur at both functions, thus di-substitutions result.
Dichloromethane (DCM; Methylene Chloride) (CAS: 75-09-2) is classified as only slightly toxic by the oral and inhalation routes. Exposure to high concentrations of dichloromethane vapor (>500 ppm for 8 h) can lead to lightheadedness, fatigue, weakness, and nausea. Contact of the compound with the eyes causes painful irritation and can lead to conjunctivitis and corneal injury if not promptly removed by washing. Dichloromethane is a mild skin irritant, and upon prolonged contact (e.g., under the cover of clothing or shoes) can cause burns after 30 to 60 min exposure. Dichloromethane is not teratogenic at levels up to 4500 ppm or embryotoxic in rats and mice at levels up to 1250 ppm.
Special Hazards of Combustion Products: Dissociation products generated in a fire may be irritating or toxic.
Incompatible with strong oxidizers, caustics; chemically active metals, such as aluminum, magnesium powders; potassium, lithium, and sodium; concentrated nitric acid causing fire and explosion hazard. Contact with hot surfaces or flames causes decomposition producing fumes of hydrogen chloride and phosgene gas. Attacks some forms of plastics, rubber and coatings. Attacks metals in the presence of moisture.
Respiratory protection: when the concentration in the air exceeds the standard, you should wear a direct gas mask (half mask). Wear air respirator during emergency rescue or evacuation. Eye protection: wear chemical safety glasses when necessary. Body protection: wear protective clothing against poison penetration. Hand protection: wear chemical resistant gloves. Others: smoking, eating and drinking are prohibited at the work site. Shower and change clothes after work. Store contaminated clothes separately and use them for standby after washing. Pay attention to personal hygiene.
