Dichloromethane has a variety of uses in production, mainly including the following aspects:
Solvent: Dichloromethane is widely used as a solvent in the production of plastics and resins, such as polyvinyl chloride (PVC) and epoxy resins, due to its good solubility. In addition, it is also used as a solvent in film production, a petroleum dewaxing solvent, an aerosol propellant, an organic synthesis extractant, etc.
Cleaning and degreasing agent: In the cleaning and laundry industry, dichloromethane is used as a degreasing agent to remove grease and oil from machinery and equipment. It is also used as a metal surface paint cleaning, degreasing and stripping agent.
Chemical synthesis: In the chemical and pharmaceutical industries, dichloromethane is used as a reaction medium for the preparation of various chemicals and pharmaceuticals, such as ampicillin, hydroxybenzyl penicillin and cephalosporin. In addition, it is also used in the production of pesticides, such as the production of myclobutanil and imidacloprid.
Refrigerant: In industrial refrigeration systems, dichloromethane is used as a refrigerant for grain fumigation and refrigeration of low-pressure freezers and air-conditioning units.
Food Industry: Dichloromethane is used in the production of decaffeinated coffee to help remove caffeine.
Other Uses: It is also used as a foaming agent, mold release agent, paint stripper, etc. in the production of polyurethane foam plastics.
The physical properties of dichloromethane include a density of 1.325 g/mL at 25 °C. It is a colorless, transparent liquid with an ether-like pungent odor. When using it, you need to pay attention to its toxicity. When it comes into contact with open flames or hot objects, it can produce highly toxic phosgene. When it comes into contact with humid air, it can hydrolyze to produce trace amounts of hydrogen chloride. Light can also promote hydrolysis and increase its corrosiveness to metals.
