styrene eji na polymers

Styrene bụ mmiri mmiri hydrocarbon doro anya nke a na-emepụta nke ọma site na ngwaahịa mmanụ ala mgbe usoro nke distillation na-esighi ike wepụ olefins na aromatics dị mkpa maka ihe kemịkal na-emepụta Styrene.Ọtụtụ osisi kemịkalụ petrochemical yiri foto dị n'aka nri.Rịba ama nnukwu kọlụm kwụ ọtọ nke a na-akpọ kọlụm distillation fractional.Nke a bụ ebe a na-ekpocha ihe ndị dị na mmanụ ala na oke okpomọkụ n'ihi na nke ọ bụla n'ime ihe ndị bụ isi kemịkalụ nwere isi ihe na-esi ísì ụtọ dị iche iche si otú a kewaa ha nke ọma.

Styrene bụ ihe a maara na okirikiri kemistri dị ka monomer.Mmeghachi omume nke monomers na-akpụ "agbụ" na ikike ijikọta na ụmụ irighiri ihe ndị ọzọ dị mkpa na mmepụta nke Polystyrene.Molecules Styrene nwekwara otu vinyl (ethenyl) nke na-ekekọrịta electrons na mmeghachi omume a maara dị ka covalent bonding, nke a na-enye ohere ịmepụta ya na plastik.Ọtụtụ mgbe, a na-emepụta Styren na usoro nzọụkwụ abụọ.Nke mbụ, alkylation nke benzene (hydrocarbon unsaturated) na ethylene iji mepụta ethylbenzene.A ka na-eji aluminom chloride catalyzed alkylation n'ọtụtụ osisi EB (ethylbenzene) gburugburu ụwa.Ozugbo emechara nke ahụ, a na-etinye EB site na usoro dehydrogenation ziri ezi site na ịgafe EB na uzuoku n'elu ihe mkpali dị ka iron oxide, aluminum chloride, ma ọ bụ n'oge na-adịbeghị anya, usoro ihe nrụnye zeolite nke edobere akwa iji nweta ụdị Styrene dị ọcha.A na-eji ihe fọrọ nke nta ka ọ bụrụ ethylbenzene niile a na-emepụta gburugburu ụwa maka nrụpụta styrene.Ọganihu ndị na-adịbeghị anya na mmepụta Styrene amụbawo ụzọ a ga-esi emepụta Styrene.Otu ụzọ na-eji Toluene na methanol kama EB.Inwe ike iji nri nri dị iche iche na-eme Styrene ka ọ bụrụ akụrụngwa bara uru nke ukwuu.

• A na-ekpo ọkụ na mmanụ cru dị ọkụ wee ghọọ vepour.

• Kọlụm ahụ na-ekpo ọkụ na ala ma na-adị jụụ n'ebe elu.
• Ka uzuoku hydrocarbon nke ọ bụla na-ebili ma jụọ oyi ruo n'ebe ọ na-esi esi mmiri, ọ na-echikọta ma na-emepụta mmiri mmiri.
• A na-ejide ụmụ irighiri mmiri mmiri (otu nke hydrocarbons nwere isi ihe na-esi ísì ụtọ) n'ime traị ma gbapụ ya.

Styrene bụkwa monomer dị mkpa na polymers ndị a:

• Polystyrene
• EPS (Polystyrene enwere ike ịgbasa)
• SAN (Styrene Acrylonitrile resins)
• SB Latex
• ABS (Acrylonitrile Butadiene Styrene Resins)
• SB Rubber (Styrene-butadiene kemgbe 1940)
• Thermoplastic Elastomers (thermoplastic rubbers)
• MBS (Methacrylate Butadiene Styrene Resins)
