Dichloromethane is also used as a refrigerant in industrial refrigeration systems, but it is very harmful, and can produce highly toxic phosgene when it comes into contact with open flames or hot objects. In case of humid air, it can be hydrolyzed to generate a small amount of hydrogen chloride, and light can also promote hydrolysis and increase the corrosiveness to metals.
For grain fumigation and refrigeration of low-pressure freezers and air-conditioning units. It is used as an auxiliary blowing agent in the production of polyether urethane foam, and as a blowing agent for extruded polysulfone foam.
