Mawu Oyamba
(2E) -2-Butene-1,4-diol, yomwe imadziwikanso kuti (2E) -2-Butene-1,4-diol, ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
(2E) -2-Butene-1,4-diol ndi madzi opanda mtundu kapena otumbululuka achikasu okhala ndi fungo lonunkhira lapadera. Mapangidwe ake amankhwala ndi C4H8O2 ndipo kulemera kwake kwa molekyulu ndi 88.11g/mol. Ili ndi kachulukidwe ka 1.057g/cm³, malo otentha a 225-230 digiri Celsius, ndipo imasungunuka muzosungunulira wamba monga madzi, ethanol ndi ether.
Gwiritsani ntchito:
(2E) -2-Butene-1,4-diol ili ndi ntchito zambiri m'makampani opanga mankhwala. Itha kugwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe organic, pokonza utomoni kupanga, zokutira patsogolo, utoto ndi intermediates mankhwala ndi mankhwala ena. Komanso, itha kugwiritsidwanso ntchito ngati zosungunulira ndi surfactant mu makampani.
Njira Yokonzekera:
Kukonzekera kwa (2E) -2-Butene-1,4-diol kungapangidwe ndi njira zosiyanasiyana. Njira imodzi yodziwika bwino ndiyo kuchepetsa butenedioic acid. Kuchepetsa uku kungagwiritse ntchito chochepetsera monga hydrogen ndi chothandizira, kapena kuchepetsa reactant monga sodium hydride kapena sulfoxide.
Zambiri Zachitetezo:
(2E) -2-Butene-1,4-diol ndi mankhwala otetezeka omwe amagwiritsidwa ntchito. Komabe, monga mankhwala, imatha kuvulaza thupi la munthu. Kukhudzana ndi khungu, maso kapena kupuma kwa nthunzi kungayambitse mkwiyo ndi kupweteka kwa maso. Choncho, pogwira ndi kugwiritsa ntchito (2E) -2-Butene-1,4-diol, njira zoyenera zotetezera ziyenera kuchitidwa, monga kuvala magolovesi otetezera ndi zipangizo zotetezera maso, ndikuonetsetsa kuti malo ogwirira ntchito ali ndi mpweya wabwino. Panthawi imodzimodziyo, iyenera kusungidwa kutali ndi moto ndikupewa kukhudzana ndi ma okosijeni amphamvu. Funsani kuchipatala mwamsanga ngati mwakhudza mwangozi kapena kudya.
