Why does vinyl chloride phase seperate.

What is vinyl chloride. The further conversion of 1 2 dichloroethane to vinyl chloride used to be carried out in the liquid phase with alkali. Vinyl chloride can even be emitted from new vinyl products. Vinyl chloride a colourless flammable toxic gas belonging to the family of organohalogen compounds and used principally in making polyvinyl chloride or pvc a widely used plastic with numerous applications.

Vinyl chloride also burns easily and is not stable at high temperatures. The endothermic cleavage of edc is conducted at 500 600 c and 25 35 bar at high flow rates in tubes made of special steels ni cr with high heat resistance. Vinyl chloride is an organochloride with the formula h 2 c chcl that is also called vinyl chloride monomer vcm or chloroethene this colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride pvc. Charcoal is used as the catalyst.

Pvc is used to make a variety of plastic products including pipes wire and cable coatings and packaging materials. Vinyl chloride is a colorless organic gas with a sweet odor. It is produced by breaking down other gasses and chemicals which creates a colorless gas at room temperature with a sweet smelling mild odor. About 13 billion kilograms are produced annually.

When used as a geomembrane plasticizer additions of 25 35 are common. 16 2 2 process technology figure 16 2 figure 16 2 flow sheet of production of vinyl chloride. However the majority of the vinyl chloride found in the environment is the result of releases from manufacturing facilities or waste disposal.

Today gasphase dehydrochlorination is used exclusively. Vinyl chloride is used primarily to make polyvinyl chloride pvc. Vinyl chloride is a colorless gas that burns easily. Pvc is produced from its monomer vinyl chloride.

Unlike some other known carcinogens vinyl chloride is a manmade substance. The reaction is a reversible gas phase reaction. Pvc geomembranes are made from pvc resin plasticizer s fillers and additives. For example elevated levels of vinyl chloride have been measured inside of new cars with vinyl interiors.

Pvc is a hard plastic that is made softer and more flexible by the addition of plasticizers the most widely used being phthalates. The major industrial preparation of vinyl chloride begins with ethylene and has two. 16 2 vinyl chloride production.
