Useful:

• Chemical Classes: Solvents -> Chlorinated Aliphatics
• Canonical SMILES: C(=CCl)Cl
• Inhalation Risk: A harmful contamination of the air will be reached quickly on evaporation of this substance at 20 °C; on spraying or dispersing, however, much faster.
• Effects of Short Term Exposure: The substance is irritating to the eyes and respiratory tract. The substance may cause effects on the central nervous system at high levels. This may result in lowering of consciousness.
• Effects of Long Term Exposure: The substance defats the skin, which may cause dryness or cracking. The substance may have effects on the liver.
• Description: Acetylene dichloride is a colourless liquid (usually a mixture of the cis and trans isomers) with a slightly acrid, chloroform-like odour. Acetylene dichloride is a chemical used mainly in the production of perfumes, dyes, and thermoplastics. The type and severity of symptoms varies depending on the amount of chemical involved and the nature of the exposure. It is incompatible with strong oxidisers, strong alkalis, potassium hydroxide, and copper. Acetylene dichloride is highly flammable and in a fire gives off irritating or toxic fumes/gases. (Acetylene dichloride usually contains inhibitors to prevent polymerisation.)
• Uses: 1,2-Dichloroethylene is used as a solvent for organic materials and as an intermediate in the synthesis of other chlorinated compounds; it may be produced by the chlorination of acetylene but is often produced as a by-product in the manufacture of other chlorinated compounds.
