Webnon-polar dichloromethane solvent in the solution, which is immiscible in water. While the solution cooled in an ice bath, a foam-like crystal began to form in the solution from the top down. After removing the crystals with vacuum filtration, a TLC analysis was performed using benzil as a reference and product dissolved in dichloromethane as the sample. Dichloromethane (DCM or methylene chloride, methylene bichloride) is an organochlorine 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 slightly polar, and miscible with many organic solvents.
