Product Details

Dichloromethane CAS#75-09-2

Dichloromethane (DCM), additionally recognized as methylene chloride, is a transparent, colorless, risky halogenated aliphatic hydrocarbon compound with an ether-like mildly candy smell. It is relatively soluble in water as properly as in most natural solvents namely; ether, ethanol, ketones, aldehydes, and phenols (1). Notably, DCM vapors are heavier than air and are generally non-explosive, stable, and non-flammable when uncovered in the air; however, temperatures above 100oC have to be avoided. Although herbal sources do no longer mostly make contributions to the world launch of DCM, the latter may also lead to the formation of the former.

Product Usage

House Hold Uses
The compound is used in bathtub refurbishing. Dichloromethane is enormously used industrially in the manufacturing of pharmaceuticals, strippers, and system solvents.
Industrial and Manufacturing Uses
DCM is a solvent that is observed in varnish and paint strippers, which are regularly used to cast off varnish or paint coatings from a number of surfaces. As a solvent in the pharmaceutical industry, DCM is used for the training of cephalosporin and ampicillin.
Food and Beverage Manufacturing
It is additionally used in manufacturing beverage and meals manufacturing as an extraction solvent. For instance, DCM can be used to decaffeinate unroasted espresso beans as properly as tea leaves. The compound is additionally used in developing hops extract for beer, liquids and different flavoring for foods, as properly as in processing spices.
Transportation Industry
DCM is commonly used in the degreasing of metallic components and surfaces, such as railroad tools and tracks as properly as aircraft components. It can additionally be used in degreasing and lubricating merchandise utilized in automobile products, for instance, elimination of the gasket and for getting ready steel components for a new gasket.
Experts in automobile often use vapor dichloromethane degreasing system to for the elimination of grease and oils from vehicle components of automobile transistor, spacecraft assemblies, plane components, and diesel motors. Today, experts are in a position to safely and shortly smooth transportation structures the use of degreasing strategies that rely on methylene chloride.
