Vinyl Chloride From Petroleum

It is produced commercially by combining a hydrocarbon feedstock namely ethylene obtained by cracking natural gas or petroleum with elemental chlorine.

Vinyl chloride from petroleum.

What is vinyl chloride. Vinyl chloride can even be emitted from new vinyl products. Therefore a plasticizer is commonly added into pvc during processing in an effort to increase its stability flexibility and workability bocque et al 2016. For example elevated levels of vinyl chloride have been measured inside of new cars with vinyl interiors.

Vinyl chloride is used primarily to make polyvinyl chloride pvc. Some monomers exist in the form of reactive gaseous chemical substances and some of these may cause health hazards when in direct contact with humans. The major issue with this process is that fact that the catalyst used mercuric chloride is a very volatile compound. Generally pure pvc has a high glass transition temperature t g and low thermal stability.

The salt is used to obtain chlorine through a process called electrolytic disassociation of salt. 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. Poly vinyl chloride pvc is one of the most widely used plastics for numerous applications. Vinyl chloride monomer vcm is the key chemical precursor to pvc.

It is so volatile that much of the development work on this. Pvc is used to make a variety of plastic products including pipes wire and cable coatings and packaging materials. Vinyl chloride is good more than 98 and the only significant side reaction is the further addition of hcl to vinyl chloride to form 1 1 dichlorethane 21. Vinyl chloride monomer polyvinyl chloride vinyl chloride monomer is the key chemical precursor to polyvinyl chloride.

About 13 billion kilograms are produced annually. The crude oil petroleum or natural gas is used to obtain ethylene. Vinyl chloride is a colorless gas that burns easily. Vinyl is a flooring material made from petroleum oil.

This is the case for polyvinyl chloride pvc which is made from vinyl chloride monomer known usually by its initials vcm through polymerisation. These floor tiles consist of polyvinyl chloride chips. It does not occur naturally and must be produced industrially for its commercial uses. Chlorine is derived from brine a solution of common salt and water.

However the majority of the vinyl chloride found in the environment is the result of releases from manufacturing facilities or waste disposal. The production process requires high energy to extract and process chlorine into this material because it needs specific conditions of heat and pressure.
