Ntchito alkenes mu makampani.

Alkenes - ndi mankhwala mankhwala hydrocarbon chilengedwe, kukhala mu iwiri ake chomangira dongosolo lina. Zikuphatikizapo ethylene, propylene, butylene, isobutylene, pentene, hexene, heptene ndi ena. Ntchito alkenes ndi zina mwa madera ambiri a makampani, komanso chuma cha dziko.

Chifukwa reactivity mkulu wa mankhwala ndi chomangira awiri, iwo ankagwiritsa ntchito monga zipangizo makampani mankhwala. Taganizirani ntchito alkenes ethylene chitsanzo. Ethylene ataima pa chiyambi cha kwa magazi mndandanda wa alkenes ntchito popanga ethylene glycol, amene nawonso ntchito kubala kupanga ulusi Dacron, antifreezes, mabomba. Kwambiri pa ntchito umachita ethylene polymerization. Ilo liri pa kutentha ndi anzawo. Polymerizing ethylene kupanga polyethylene amene ntchito ngati maziko kwa kupanga mapulasitiki, rubbers kupanga ndiponso mafuta. Polyethylene macromolecules lalifupi ndi madzi lubricant. Ngati chiwerengero cha mayunitsi mu molekyulu ndi polyethylene 1.5-3 zikwi, ndiye n'zotheka kutulutsa phukusi film, mabotolo, ziwiya pulasitiki. Ndi kuwonjezeka unyolo kutalika zisanu ndi zikwi zisanu polyethylene amakhala olimba, chuma cholimba imene chopangidwa zovekera chitoliro. Wa alkenes ena komanso kukonzekera polymerization ulusi kupanga. Mkulu mphamvu polypropylene ali katundu anachokera ku propene.

Yatikhudza ethylene ndi mankhwala enaake a hydrogen ethyl mankhwala enaake aumbike, amene ntchito mankhwala kwa mankhwala oletsa ululu pamalopo. Ntchito alkenes ndi anafotokozanso ndi luso kuchita ndi madzi kupanga alcohols. Choncho, m'kati ethylene hydration anachita analandira mowa ethyl. Iwo anapeza ntchito zawo monga zipangizo kupanga mankhwala organic, lacquers, mapulasitiki, ndi mafakitale zodzikongoletsera zikutanthauza alkene okusayidi, amene anapanga kuchokera mankhwala ndi mgwirizano awiri pa makutidwe ndi okosijeni wa mpweya mumlengalenga. Chifukwa cha Kuwonjezera zimene alkenes ndi halogen-haloalkanes anakonza. Choncho, dichloroethane ku ethylene zakonzedwa, amene ntchito ngati zosungunulira kupasuka penti ndi vanishi, decontaminating nkhokwe, nthaka, tirigu, ndipo monga zomatira kuti ubale mapulasitiki. The zopangira kwa yopanga asidi acetic, ethyl benzene, styrene ndi zina zambiri mankhwala malonda zofunika mankhwala monga ethylene. katundu mankhwala kudziwa ukulu wa ntchito ngati maziko a zinthu zonsezi. Mkulu reactivity chifukwa kukhalapo kwa ubwenzi wachiphamaso. zochita Kuwonjezera pa alkenes zidzachitika pa ubale awiri. The chifukwa ndi akuwaza wa π-kulankhulana ndi maphunziro pamalo ake awiri σ-kumangidwa.

Ntchito alkenes si ntchito zawo monga zopangira kwa ambirimbiri mankhwala. Mwachitsanzo, ethylene ntchito storages, ndi greenhouses kuti imathandizira pa yakucha wa zipatso ndi ndiwo zamasamba, komanso zomera zikule yang'anira.
