Isticmaalka alkenes in industry ee.

Alkenes - a walax kiimiko ah nooca shidaalka, isagoo in ay qaab-dhismeedka ka mid ah bond double. Kuwaas waxaa ka mid ethylene, propylene, butylene, isobutylene, pentene, hexene, heptene iyo kuwa kale. Isticmaalka alkenes waa caadiga ah ee meelo badan oo ka mid ah warshadaha, iyo sidoo kale dhaqaalaha dalka.

Maaddaama ay falcelin sare xeryahooda la bond a double, waxay si weyn loo isticmaalaa sida alaabta ceeriin ee warshadaha kiimikada. Tixgeli codsiga ah ee tusaale ahaan alkenes ethylene. Polymer bilowga taagan taxanaha homologous of alkenes loo isticmaalo soo saarida tones ethylene, taas oo markeeda loo isticmaalaa in lagu soo saaro fiiloyin dardaro Dacron, antifreezes, waxyaabaha qarxa. meel muhiim ah in codsiga ciyaara polymerization ethylene ah. Waxa ay maamushaa heerkulka sare iyo cadaadis. Polymerizing ethylene la xirrira polyetylen kaasi oo loo adeegsaday saldhig ahaan wax soo saarka ee balaastigga, masaxado dardaro iyo shidaalka. Polyetylen macromolecules gaaban waa labeen ah dareere. Haddii tirada unugyada ee Britain waa polyetylen 1.5-3 kun, ka dibna waxaa suurtagal ah in ay soo saaraan film baakadaha, dhalooyinka, maacuun caag ah. By kordhaya dhererka silsilad shan ah in lix kun oo polyetylen noqdo shirkad, wax waara kaas oo ah tuubbooyin macmalay. Oo ka mid ah alkenes kale ayaa sidoo kale diyaarisay by polymerization macdantaa dardaro. polypropylene xoog High wuxuu leeyahay sifooyin oo ka soo jeeda propene.

ethylene ficil la chloride ethyl chloride hydrogen waxaa la aasaasay, taas oo waxaa loo isticmaalaa in daawada suuxinta maxaliga ah. Isticmaalka alkenes waxaa sidoo kale la xiriira awoodda ay u leeyihiin in ay fal biyo si ay u sameeyaan alcohols ah. Sidaas darteed, in habka ficil fuuq ethylene waa la helay khamriga ethyl. Waxay ka heleen isticmaalka sida alaabta ceeriin soo saarka xeryahooda organic, lacquers, bacyaal, iyo warshadaha qurxiyo macnaheedu waa xabagta alkene, kuwaas oo loo soo sameeyey xeryahooda la bond labanlaab intii lagu qayilo ee ogsijiin atmosfeerta. Sidaas darteed cadaanyo Intaa waxaa dheer ee alkenes iyo halogeen-haloalkanes diyaariyey. Sayidka, dichloroethane ka ethylene waa la diyaariyey, kaas oo waxaa loo isticmaalaa sida dareeraha ah si ay u milmaan rinjiga iyo varnishes, decontaminating Maqsinnadaydii, ciidda, hadhuudh, iyo sida xabag ah in bacyaal bond. Qoraalkani wuxuu ku xawliga ah u wax soo saarka ee acid acetic, benzene ethyl, styrene oo kiimiko ah oo badan oo kale oo ganacsi oo muhiim ah sida ethylene. guryaha Chemical ogaado baaxadda codsiga saldhig ahaan walxaha oo dhan. falcelin High ay sabab u tahay jiritaanka bond a double. reactions Intaa waxaa dheer in alkenes dhacaan debaajiga double. Natiijadu waxay tahay qaybsama ee π-isgaarsiinta iyo waxbarashada in ay meel laba σ-silsilado.

Isticmaalka alkenes aan ku xaddidnayn ay u isticmaalaan sidii qalab ceeriin for tiro badan oo xeryahooda. Tusaale ahaan, ethylene waxaa loo isticmaalaa in storages ah, iyo in lagu koriyo si loo dardar-Bisaylkiisa ee midhaha iyo khudaarta, iyo sidoo kale jaangooyaha koritaanka dhirta a.
