Mawu Oyamba
2,3-dimethyl-2-butene (DMB) ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, njira zopangira ndi chitetezo:
Ubwino:
Maonekedwe: DMB ndi madzi opanda mtundu.
Kusungunuka: Amasungunuka mu zosungunulira zambiri monga ethanol, etha, ndi ma hydrocarbon.
Kachulukidwe: Kachulukidwe ake ndi pafupifupi 0.68 g/cm³.
Poizoni: DMB ilibe poyizoni pang'ono, koma kuwonetseredwa mopitirira muyeso kungayambitse kuyabwa m'maso ndi kuyabwa pakhungu.
Gwiritsani ntchito:
Kaphatikizidwe ka Chemical: DMB imagwiritsidwa ntchito kwambiri popanga organic monga zosungunulira, zapakatikati, kapena zosungunulira.
Makampani amafuta: DMB imagwiritsidwanso ntchito ngati mankhwala ofunikira pakuyenga mafuta a jute ndi njira za petrochemical.
Njira:
DMB imakonzedwa mwachizolowezi ndi alkylation ya methylbenzene ndi propylene. Njira zenizeni zimaphatikizapo kuchitapo kanthu kwa methylbenzene ndi propylene pa kutentha koyenera ndi kupanikizika pamaso pa chothandizira kupanga DMB.
Zambiri Zachitetezo:
Monga zosungunulira organic, DMB ndi kusakhazikika. Mukamagwiritsa ntchito, ndikofunikira kusunga mpweya wabwino ndikupewa kukhudzidwa kwambiri.
Zitha kuyambitsa kuyabwa mukakumana ndi khungu ndi maso. Kulumikizana kwa nthawi yayitali, kupuma, kapena kumeza kuyenera kupewedwa.
Posunga ndikugwiritsa ntchito DMB, kuyenera kupewedwa ndi ma oxidants amphamvu ndi ma asidi amphamvu.
Mukakhudzana ndi mankhwalawa, muzimutsuka nthawi yomweyo pakhungu kapena maso ndi madzi ambiri ndikupita kuchipatala.
