Product Name | Methylene Chloride |
Introduction | Methylene chloride is a colorless, transparent, heavier than water, volatile liquid that has an ether-like odor and sweetness,does not burn, but mixes with a high concentration of oxygen to form an explosive mixture.Methylene chloride is slightly soluble in water, and most commonly used as organic solvents. Methylene chloride can be quickly dissolved in phenol, aldehyde, ketone,glacial acetic acid, triethyl phosphate, formamide, cyclohexylamine, acetoacetate. |

Application
Methylene chloride has the advantages of strong solubility and low toxicity, and is widely used in the manufacture of safety film,polycarbonate, the rest as paint solvent, metal degreaser, gas smoke ejector, polyurethane foaming agent, demoulding agent, paint remover.
Methylene chloride is used as a reaction medium in the pharmaceutical industry for the preparation of ampicillin,
hydroxybenzicillin and aventomycin. Methylene chloride is also used as solvent in film production, solvent for petroleum dewaxing, aerosol propellant, solvent for organic synthesis extraction, foaming agent for foam production such as polyurethane and metal cleaner.
Methylene chloride is mainly used in film production and medicine in China. Methylene chloride is also used to make decaffeinated coffee. The coffee is steamed so that the caffeine dissolves and floats to the surface, and then methylene chloride is used to remove the caffeine.
