1,1-dichloroethylene, also called 1,1-Dichloroethene, vinylidene chloride or 1,1-DCE, is an organochloride with the molecular formula C2H2Cl2. It is a colourless liquid with a sharp odour. [1] 1,1-Dichloroethylene turns into a vapour quickly at room temperature and burns fast. 1,1-Dichloroethylene is a manmade chemical and is not found naturally in the environment. [2] Like most chlorocarbons, it is poorly soluble in water, but soluble in organic solvents. 1,1-dichloroethylene was the precursor to the original cling-wrap for food, but this application has been phased out.
