UTHENGA WABWINO KWAMBIRI

Kampani yathuamagwirizana ndi East China Yunivesite ya sayansi ya sayansi ndi ukadaulo, ndipo poyamba amasunga mosalekeza mu ketulo komanso njira yopitilira yopangaUbweya Wamwazi. Anazindikira kuti zomwe zimachitika pamtunda wochepa komanso kuyendetsa galimoto mopitirira muyeso, ndikupangitsa mtunduwo kukhala wokhazikika komanso wosuta mtengo wotsika. Tili ndi unyolo wokwanira woponya zinthu, ndipo tili ndi kupita patsogolo kwakukulu mu njira ndi mitundu yopanga. Zogulitsa zapadera zomwe zimapangidwa kuti ziziitanitsa zimapezekanso malinga ndi zomwe makasitomala amachita. Tili ndi magulu aukadaulo akusangalala ndi mbiri yabwino m'makampaniyo popanga, kafukufuku ndi ntchito, omwe angathetse mavuto anu nthawi yake.

Mu 1931, a Adskins a Adskins adazindikira kuti hydrogenation ya furforth ya furforth ya kutentha kwa furhuran, ndipo kusankhidwa kwazinthuzo kumatha kusintha kutentha ndi ma carelytic. Malinga ndi zochitika zosiyanasiyana, njira ya hydrogenation ya furfarn ya furforyl mowa zimatha kugawidwa ndi njira yamagetsi yomwe imatha kutentha, yomwe imatha kugawika njira yayitali (9 ~ 8mm).

Gawo la Gawo la Madzimadzi

Madzi a Sheser Hydrogenation ndikuyimitsa chothandizira mu furfiral pa 180 ~ 210 ℃, kupanikizika kwambiri kapena kupanikizika kwambiri hydrogenation, chipangizocho ndi nsanja yopanda kanthu. Kuti muchepetse katundu kutentha, kuchuluka kwa furfural nthawi zambiri kumayendetsedwa komanso nthawi yochita (wamkulu kuposa 1h) adakhala nthawi yayitali. Chifukwa cha zakumbuyo za zida, zochita za hydrogenation sizingakhale mu gawo la ubweya wa druphyl, ndipo imathanso kupanga zopangidwa ndi 22Furfirfuran ndi tetrahydrofuraran kumwa mowa, ndipo zovuta kubwezeretsa chonyansa, ndipo chovuta kuchititsa kuwonongeka kwa cromium. Kuphatikiza apo, njira ya gawo la madzi imafunikira kugwira ntchito mopanikizika, yomwe imafunikira zida zapamwamba. Pakadali pano, njirayi imagwiritsidwa ntchito makamaka m'dziko lathu. Zovuta kwambiri ndizomwe zimabwezedwa kwambiri ndi njira yamadzimadzi. Komabe, kupanga kwa furfuryl mowa ndi gawo lamadzimadzi omwe amakhala ndi vuto lochepa (1 ~ 1.3m) lanenedwa ku China, ndipo zokolola zambiri zapezeka.

Monga imodzi mwazipatso zopangira synthesis, zitha kugwiritsidwa ntchito kupanga levlinic acid, furan ule ndi zinthu zosiyanasiyana, furforl mowa - urea utomoni. Kuzizira kozizira kwa ma pulasitala zopangidwa kuchokera kumayiko kuli bwino kuposa kwa a Carial ndi Octanol etters. Komanso ma sotima abwino oti fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a fura a Fura a Fura a Fura a Furan, ndi utoto, ndi mafuta a rocke. Kuphatikiza apo, imagwiritsidwanso ntchito mu ulusi wopangidwa, mphira, mankhwala ophera tizilombo ndi mafakitale.
