The chemical compound 1,2-dichloroethane, commonly known as ethylene dichloride (EDC), is a chlorinated hydrocarbon. It is a colourless liquid with a chloroform -like odour . The most common use of 1,2-dichloroethane is in the production of vinyl chloride , which is used to make polyvinyl chloride (PVC) pipes, furniture and automobile ...

Notwithstanding the provisions of this paragraph, the packing group and hazard zone of a tear gas substance is as assigned in Column 5 of the 49CFR 172.101 Table. The packing group and hazard zone for Division 6.1 mixtures that are poisonous (toxic) by inhalation may be determined by one of the following methods:
Several other methods have been developed. When 1,2-dichloroethane is heated to 400 °C with chlorine, tetrachloroethylene is produced: ClCH 2 CH 2 Cl + 3 Cl 2 → Cl 2 C=CCl 2 + 4 HCl. This reaction can be catalyzed by a mixture of potassium chloride and aluminium chloride or by activated carbon.
Dichloroethane can refer to either of two isomeric organochlorides with the molecular formula C 2 H 4 Cl 2: 1,1-Dichloroethane (ethylidene chloride) 1,2-Dichloroethane (ethylene dichloride)
A gas is a substance which (a) at 50 °C (122 °F) has a vapor pressure greater than 300 kPa (43.51 PSI) or (b) is completely gaseous at 20 °C (68 °F) at a standard pressure of 101.3 kPa (14.69 PSI). Gases are assigned to one of three divisions division 2.1 Flammable gas; division 2.2 Non flammable, Non-toxic gas; division 2.3 Toxic gas
[1] [2] Highly Toxic: a gas that has a LC 50 in air of 200 ppm or less. [2] NFPA 704: Materials that, under emergency conditions, can cause serious or permanent injury are given a Health Hazard rating of 3. Their acute inhalation toxicity corresponds to those vapors or gases having LC 50 values greater than 1,000 ppm but less than or equal to ...
For mixing with raw gasoline, TEL was most commonly supplied in the form of "Ethyl Fluid", which consisted of TEL blended with 1,2-dichloroethane and 1,2-dibromoethane. Ethyl Fluid also contained a reddish dye to distinguish treated from untreated gasoline and discourage the use of leaded gasoline for other purposes such as cleaning. [27]
