Vinyl chloride to pvc catalyst.

Pvc is used to make a variety of plastic products including pipes wire and cable coatings and packaging materials. Pvc comes in two basic forms. Pvc is made by subjecting vinyl chloride to highly reactive compounds known as free radical initiators. Vinyl chloride ch 2 chcl is most often obtained by reacting ethylene with oxygen and hydrogen chloride over a copper catalyst.

Under the action of the initiators the. It does not occur naturally and must be produced industrially for its commercial uses. 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 is a colorless gas that burns easily.

Using a suitable solid mineral that adsorbs the chlorine released in the decomposition of the pvc. Rigid sometimes abbreviated as rpvc and flexible. In order to explore the possibility of efficient chlorine removal from the poly vinyl chloride pvc containing waste plastics simultaneous degradation and dechlorination of pvc at a relatively low temperature was investigated by changing the atmosphere gas and metal oxide as catalyst and or adsorbent catalyst adsorbent. Vinyl chloride is used primarily to make polyvinyl chloride pvc.

What is vinyl chloride. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed expired lifetime application number us835898a inventor. Catalyst vinyl chloride peroxy dicarbonate polymerization suspension prior art date 1959 08 25 legal status the legal status is an assumption and is not a legal conclusion. It is a carcinogenic gas that must be handled with special protective procedures.

Pvc is the world s third most widely produced synthetic plastic polymer after polyethylene and polypropylene about 40 million tons of pvc are produced each year. About 13 billion kilograms are produced annually. Suspension and emulsion polymerization of vinyl chloride monomer using free radical initiators. Vinyl chloride ch 2 chcl also known as chloroethylene is most often obtained by reacting ethylene with oxygen and hydrogen chloride over a copper catalyst it is a toxic and carcinogenic gas that is handled under special protective procedures.

Catalytic pyrolysis of poly vinyl chloride as a viable way of waste management randy santos fermin the main purpose of this investigation is to achieve the dechlorination and cracking of pvc producing a low chlorinated oil using a single step process.
