Petrochemicals are chemical products made from raw materials of petroleum or other hydrocarbon origin. Although some of the chemical compounds that originate from petroleum may also be derived from coal and natural gas, petroleum is the major source. They are used in products such as detergents, fertilizers, medicines, paints, plastics, synthetic fibres, and synthetic rubber.

  • Petrochemicals are chemical products made from raw materials of petroleum or other hydrocarbon origin. Although some of the chemical compounds that originate from petroleum may also be derived from coal and natural gas, petroleum is the major source. They are used in products such as detergents, fertilizers, medicines, paints, plastics, synthetic fibres, and synthetic rubber. The largest petrochemical industries are in the United States and Western Europe, though the major growth in new production capacity is in the Middle East and Asia. There is a substantial inter-regional trade in petrochemicals of all kinds. World production of ethylene is around 110 million tons per year, of propylene 65 million tons, and of aromatic raw materials 70 million tons. Primary petrochemicals are divided into three groups depending on their chemical structure: Olefins - include ethylene, propylene, and butadiene. Ethylene and propylene are important sources of industrial chemicals and plastics products. Butadiene is used in making synthetic rubber. Aromatic Petrochemicals - include benzene, toluene, and xylenes. Benzene is used in the manufacture of dyes and synthetic detergents. Toluene is used in making explosives. Manufacturers use xylenes in making plastics and synthetic fibres. Synthesis gas - is a mixture of carbon monoxide and hydrogen, and is used to make the petrochemicals ammonia and methanol. Ammonia is used in making fertilizers and explosives whereas methanol serves as a source for other chemicals. epichlorohydrin - chloro-oxirane; used in epoxy resin formation epoxy resins - a type of polymerizing glue from bisphenol A, epichlorohydrin, and some amine or polyols benzoic acid - carboxybenzene caprolactam nylon mixed xylenes - any of three dimethylbenzene isomers, could be a solvent but more often precursor chemicals ortho-xylene - both methyl groups can be oxidized to form (ortho-)phthalic acid phthalic anhydride para-xylene - both methyl groups can be oxidized to form terephthalic acid dimethyl terephthalate - can be copolymerized to form certain polyesters polyesters - although there can be many types, polyethylene terephthalate is made from petrochemical products and is very widely used. purified terephthalic acid - often copolymerized to form polyethylene terephthalate polyesters
  • Petrokemikaali (eng. Petrochemical) on öljyteollisuudessa käytetty käsite. Sillä tarkoitetaan öljyjalostuksen välituotetta. Petrokemikaalia käytetään muun muassa kemiantuotteiden ja polymeerien raaka-aineena.
  • L'industria petrolchimica si occupa essenzialmente della produzione di prodotti semilavorati impiegando come materia prima gas naturale o frazioni idrocarburiche provenienti dalla distillazione del petrolio. Quest'industria è caratterizzata da grandi capacità produttive e basso valore aggiunto per unità di prodotto, condizioni favorevoli all'applicazione delle economie di scala. Gli impianti petrolchimici si distinguono quindi per le grandi dimensioni il cui limite superiore è dettato essenzialmente dalle tecnologie cantieristiche disponibili e dall'operabilità. I prodotti dell'industria petrolchimica si definiscono intermedi, in quanto non raggiungono il mercato degli utenti finali, ma sono impiegati come prodotto di partenza per la sintesi di altre molecole.
  • Petrokjemiske produkter er materialer som er produsert fra petroleum. Selv om enkelte av de kjemiske forbindelsene også kan produseres fra andre råvarer som kull eller naturgass, så er det petroleum som er hovedkilden. Mesteparten av råoljen brennes som bensin og diesel, på tross av at en lang rekke med organiske forbindelser er avhengig av samme råvare. De to hovedtypene av petrokjemiske råvarer er olefiner og aromater.
