Dichloromethane (DMC) is soluble in methanol and water, but its solubility decreases with increasing temperature and water content.
Solubility of Dichloromethane (DMC)
Dichloromethane liquid is an organochlorine compound commonly used as an industrial solvent, refrigerant and disinfectant. Dichloromethane can dissolve in methanol and water, but its solubility is affected by temperature and water content. At 20°C, the solubility of methylene chloride is about 20 g/L in pure water and about 30 g/L in methanol containing 5% water.
dichloromethane uses
- Solvent Application: Dichloromethane (DMC) is widely used as a highly effective solvent in coatings, paints, inks, adhesives, etc. It can effectively dissolve resins, rubbers and other polymer materials.
- Paint stripper: Due to its strong solubility and volatility, it is the main component of paint stripper commonly used in metal surface treatment.
- Pharmaceutical industry: Dichloromethane (DMC) is used as a reaction solvent and extractant in the process of drug synthesis, especially in the production process of antibiotics and other drugs.
- Plastics processing: Dichloromethane liquid is used as a processing aid in the production of engineering plastics such as polycarbonate, polyurethane, etc.
- Metal cleaning: Dichloromethane liquid is used in the cleaning of precision instruments and electronic components, and can effectively remove grease and dirt.
- Foaming agent: used as a physical foaming agent in the production of certain foam.
- Refrigerant: although less used, it still has certain application in specific low temperature equipment.
