Since both raw materials are inexpensive readily.
Vinyl chloride from petroleum.
However the majority of the vinyl chloride found in the environment is the result of releases from manufacturing facilities or waste disposal.
Therefore a plasticizer is commonly added into pvc during processing in an effort to increase its stability flexibility and workability bocque et al 2016.
This is the case for polyvinyl chloride pvc which is made from vinyl chloride monomer known usually by its initials vcm through polymerisation.
It does not occur naturally and must be produced industrially for its commercial uses.
What is vinyl chloride.
Vinyl chloride is a colorless gas that burns easily.
The crude oil petroleum or natural gas is used to obtain ethylene.
Vinyl is a flooring material made from petroleum oil.
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.
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.
Vinyl chloride monomer vcm is the key chemical precursor to pvc.
Pvc is widely used in medical applications piping systems siding irrigation and sewer systems electrical conduits window frames water distribution systems wire and cable insulation flooring and wallcoverings fencing.
Vinyl chloride can even be emitted from new vinyl products.
Pvc is used to make a variety of plastic products including pipes wire and cable coatings and packaging materials.
Vinyl chloride monomer polyvinyl chloride vinyl chloride monomer is the key chemical precursor to polyvinyl chloride.
The major issue with this process is that fact that the catalyst used mercuric chloride is a very volatile compound.
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.
Chlorine is derived from brine a solution of common salt and water.
Generally pure pvc has a high glass transition temperature t g and low thermal stability.
Polyvinyl chloride or vinyl compound is chiefly made from two basic substances salt and crude oil.
The production process requires high energy to extract and process chlorine into this material because it needs specific conditions of heat and pressure.
About 13 billion kilograms are produced annually.
It is so volatile that much of the development work on this.
These floor tiles consist of polyvinyl chloride chips.
It is produced commercially by combining a hydrocarbon feedstock namely ethylene obtained by cracking natural gas or petroleum with elemental chlorine.
