1,2-Dichloroethylene Specification

The systematic name of this chemical is 1,2-dichloroethene. With the CAS registry number 540-59-0 and EINECS 208-750-2, it is also named as 1,2-DCE. The product's categories are Alkenyl; Halogenated Hydrocarbons; Organic Building Blocks. It is clear colorless to pale yellow liquid with a sharp, harsh odor. It can exist as either of two geometric isomers, cis-1,2-dichloroethene or trans-1,2-dichloroethene. When heated to decomposition it emits highly toxic fumes of Cl⁻. So the storage environment should be well-ventilated, low-temperature and dry. Keep 1,2-Dichloroethylene separate from oxidant.

The other characteristics of this product can be summarized as: (1)ACD/LogP: 1.75; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.74; (4)ACD/LogD (pH 7.4): 1.74; (5)ACD/BCF (pH 5.5): 12.47; (6)ACD/BCF (pH 7.4): 12.47; (7)ACD/KOC (pH 5.5): 211.84; (8)ACD/KOC (pH 7.4): 211.84; (9)#H bond acceptors: 0; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 0; (12)Polar Surface Area: 0 Å²; (13)Index of Refraction: 1.453; (14)Molar Refractivity: 21.07 cm³; (15)Molar Volume: 77.9 cm³; (16)Polarizability: 8.35×10^-24 cm³; (17)Surface Tension: 25.9 dyne/cm; (18)Enthalpy of Vaporization: 27.93 kJ/mol; (19)Vapour Pressure: 333 mmHg at 25°C.

Preparation of 1,2-Dichloroethylene: It can be obtained by dechlorination of 1,1,2,2-tetrachloroethane with zinc powder or iron powder.

Uses of 1,2-Dichloroethylene: It is used as a solvent for waxes, resins, polymers, fats, and lacquers. It is also used as an intermediate in the preparation of other chlorinated solvents. Whats more, it can be used to produce chloronitroacetic acid. This reaction needs reagent HNO₃ and H₂SO₄. The yield is 52%.

1,2-Dichloroethylene can produce chloronitroacetic acid

When you are using this chemical, please be cautious about it as the following:
It is highly flammable, so people should keep it away from sources of ignition. It is not only harmful by inhalation, but also harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment. People should not empty into drains and avoid releasing to the environment. Refer to special instructions / safety data sheets.

People can use the following data to convert to the molecule structure.
1. SMILES:ClC=CCl
2. InChI:InChI=1/C2H2Cl2/c3-1-2-4/h1-2H
3. InChIKey:KFUSEUYYWQURPO-UHFFFAOYAW
