Infobox disclaimer and references

1,1-Dichloroethene, commonly called 1,1-dichloroethylene or 1,1-DCE, is an organochloride with the molecular formula C2H2Cl2. It is a highly flammable, colorless liquid with a sharp, harsh odor. It is insoluble in water, but soluble in ethanol, diethyl ether, acetone, benzene, and chloroform.

1,1-DCE is used as a comonomer in the polymerization of vinyl chloride, acrylonitrile, and acrylates.

1,1-DCE is used in semiconductor device fabrication for growing high purity silicon dioxide (SiO2) films.

The health effects from exposure to 1,1-DCE are primarily on the central nervous system, including symptoms of sedation, inebriation, convulsions, spasms, and unconsciousness at high concentrations.[1]
