bp of dichloromethane is an organic solvent that is volatile and has a light sweet aroma. It is non-miscible with water, but is miscible with most other organic solvents making it ideal for many chemical processes where a solvent is needed.
Using methylene chloride for degreasing applications
Methylene chloride is used as a degreaser in a variety of applications, including the removal of oil and grease from railroad equipment, automobiles, airplane components, diesel engines, and other transportation systems. It also has many industrial uses in the manufacturing of drugs, as a solvent for metal cleaning and fi nishing, and as an extraction solvent for spices and hops.
DCM is a volatile, non-flammable liquid that vaporizes at room temperature. This characteristic makes it a good choice for aerosol propellants because it can be poured from the can without risk of combustion.
Exposure to DCM is primarily through inhalation, which can cause serious health effects such as dizziness and carbon monoxide poisoning. DCM is considered a carcinogen and its use has been reduced in recent years.
It is not a food additive, but it is commonly found in paint stripper products. Workers who use these products are at high risk of exposure to DCM.
DCM is a strong oxidizer and can react vigorously with active metals such as lithium, sodium, and potassium, and with bases such as potassium tert-butoxide. It is also incompatible with strong caustics and oxidizers, and with chemically active metal powders such as aluminum or magnesium. It also corrodes some types of stainless steels, nickel, and copper on contact with water.
