Also known as methylene chloride, dichloromethane (DCM) is a transparent, colorless, volatile halogenated aliphatic hydrocarbon compound with an ether-like mildly sweet smell. It is moderately soluble in water as well as in most organic solvents namely; ether, ethanol, ketones, aldehydes, and phenols (1). Notably, DCM vapors are heavier than air and are normally non-explosive, stable, and non-flammable when exposed in the air; however, temperatures above 100oC must be avoided. Although natural

Chemical reaction between dichloromethane and solid carbon dioxide I studied heat transfer liquids with low melting point (coolants), and how fast their temperature decreases when they are contacting with solid carbon dioxide. Nearly all liquids (brines, glycols etc.) that I studied have similar behavior, except dichloromethane. When I put solid carbon dioxide gra...more+Jun 06 2021
