Dichloromethane (DCM or methylene dichloride) is an organochloride compound with the formula CH2Cl2. This colorless, volatile liquid with a chloroform-like, sweet odour is widely used as a solvent. Although it is not miscible with water, it is polar, and miscible with many organic solvents.
Methylene Dichloride is used in the Food Industry for decaffeination of coffee and tea, for making hop extracts, and flavourings. The Plastic Industry also uses Methylene Dichloride to weld plastics, to seal electric meter casings, and in plastic welding adhesives.
