Product Name:1,1-Dichloroethylene
English Name:1,1-Dichloroethylene
CAS No.:75-35-4
Aliases:Vinylidene chloride, Vinylidene dichloride, 1,1-Dichloroethene
Molecular Formula:C2H2Cl2
Physical Properties:Colorless clear liquid with a characteristic odor, easily vaporized. Molecular weight 96.94. Melting point -122°C, boiling point 31.6°C at 760 mmHg, density 1.213 g/cm³ at 20°C, refractive index 1.4259 at 20°C, flash point -23°C (-9°F), vapor pressure 601 mmHg at 25°C, vapor density 3.46 (vs air). Slightly soluble in water (2.5 g/L at 20°C), soluble in many organic solvents. Stable but highly flammable; vapor may travel a long distance to an ignition source. Incompatible with strong oxidizers, alcohols, halides, copper, and aluminum.
Uses:Mainly used as a monomer for producing vinylidene chloride (PVDC) resins and copolymers. The resulting polymers exhibit excellent gas/moisture barrier, heat resistance and chemical resistance, widely used in food packaging, cling films, coatings, inks and adhesives. It also serves as an intermediate in organic synthesis.
Technical Specifications:
Purity: ≥99.9%
Appearance: Colorless transparent liquid
Density (20°C): ~1.213 g/cm³
Boiling point (760 mmHg): 31.6°C
Packaging: 200kg/drum
