Preparation of Perchlorethylene: this chemical can be prepared by the reaction of 1,2-Dichloroethane with Chlorine. This reaction can be catalyzed by a mixture of potassium chloride and aluminium chloride at temperature of 400 °C.
ClCH2CH2Cl + 3 Cl2 → Cl2C=CCl2 + 4 HCl
Uses of Perchlorethylene: thos chemical is an excellent solvent for organic materials. It is often used in dry cleaning. And it is also used as a mixture with other chlorocarbons to degrease metal parts in the automotive and other metalworking industries. Additionally, it can be used as paint stripper and spot remover. It has been used for the treatment for hookworm infestation. Furthermore, it can be used as an intermediate in the manufacture of HFC-134a and related refrigerants.
When you are using this chemical, please be cautious about it as the following: it may cause damage to health which is reflected in some aspects. It is toxic by inhalation and if swallowed or in contact with skin, and may even have very serious irreversible effect. Then it has limited evidence of a carcinogenic effect to our health. It is not only harmful to our health but also to our environment. This is dangerous for the environment for it may present an immediate or delayed danger to one or more components of the environment; Then it is toxic to aquatic organisms and may cause long-term adverse effects in the aquatic environment. What's more, it is highly flammable because it may catch fire in contact with air, only needing brief contact with an ignition source, and it has a very low flash point or evolve highly flammable gases in contact with water.
People can use the following data to convert to the molecule structure.
(1)Canonical SMILES: C(=C(Cl)Cl)(Cl)Cl
(2)InChI: InChI=1S/C2Cl4/c3-1(4)2(5)6
