DCM is produced by treating either methyl chloride or methane with chlorine gas at **0–**0 °C. At these temperatures, both methane and methyl chloride undergo a series of reactions producing progressively more chlorinated products.[1]
CH4 + Cl2 → CH3Cl + HClCH3Cl + Cl2 → CH2Cl2 + HClCH2Cl2 + Cl2 → CHCl3 + HClCHCl3 + Cl2 → CCl4 + HClThe output of these processes is a mixture of methyl chloride, dichloromethane, chloroform, and carbon tetrachloride. These compounds are separated by distillation.
[edit]UsesDCM's volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes. Concerns about its health effects have led to a search for alternatives in many of these applications.
It is widely used as a paint stripper and a degreaser. In the food industry, it has been used to decaffeinate coffee and tea as well as to prepare extracts of hops and other flavorings. Its volatility has led to its use as an aerosol spray propellant and as a blowing agent forpolyurethane foams.
