Dichloroethane (chemical formula: c2h4cl2; Cl (CH2) 2Cl, formula quantity: 98.97), i.e. 1,2-dichloroethane, is a kind of halogenated hydrocarbon, commonly expressed by EDC [1]. The melting point of colorless or light yellow transparent liquid is - 35.7 ℃, the boiling point is 83.5 ℃, the density is 1.235g/cm3, and the flash point is 17 ℃. Insoluble water is mainly used as an intermediate in the production process of vinyl chloride (PVC monomer), and also as a solvent.
Dichloroethane is a colorless chloroform like liquid at room temperature. It is toxic and has potential carcinogenicity. Possible solvent substitutes include 1,3-dioxane and toluene. Dichloroethane is used as solvent and intermediate of trichloroethane. Used as solvent of wax, fat, rubber and grain insecticide.
After use, dichloroethane will become dirty and lose the cleaning ability. If these dirty dichloroethane solvents are recycled by Calstar solvent recovery machine, the purchase cost of dichloroethane can be reduced, and the environmental pollution caused by waste dichloroethane can also be reduced. So how does the Calstar solvent recovery machine turn waste dichloroethane into a treasure?
The boiling point of dichloroethane is 83.5 ℃. After heating, dichloroethane will be converted into steam. The solvent recovery machine can turn the dichloroethane steam into clean liquid through the condensation device, and separate the impurities mixed in dichloroethane, so as to realize the purpose of recycling dichloroethane.
The brand of Calstar has been in the solvent recovery machine industry for more than 20 years, and has accumulated the praise of tens of thousands of customers. Many customers have said that the cost saved by using the solvent recovery machine is more than the cost of purchasing the machine, because each time the recovered solvent can be put into use again, which reduces a lot of solvent procurement costs, and also reduces the damage of waste solvent to the environment.
