Mawu Oyamba
2,5-Dimethylfuran ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 2,5-dimethylfuran:
Ubwino:
- Maonekedwe: 2,5-Dimethylfuran ndi madzi opanda mtundu ndi fungo lachilendo.
- Kusungunuka: kusungunuka mu zosungunulira organic monga ethanol ndi ether, osasungunuka m'madzi.
- Kukhazikika: Ndiwokhazikika kutentha kwa chipinda, koma imayenera kutetezedwa ku kuwala ndi kusindikizidwa.
Gwiritsani ntchito:
- 2,5-dimethylfuran nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira mumakampani opanga mankhwala, makamaka pakusungunula ma polima, monga ma polima, ma resin, ndi zina zambiri.
Njira:
- 2,5-Dimethylfuran ikhoza kukonzedwa ndi momwe furan imachitira ndi ethylene. Choyamba, zochita zowonjezera za furan ndi ethylene pansi pa chothandizira cha asidi zimachitika, kenako makonzedwe a alkali-catalyzed amachitika kuti apange 2,5-dimethylfuran.
Zambiri Zachitetezo:
- 2,5-Dimethylfuran imakwiyitsa komanso yoledzeretsa, ndipo ikhoza kukhala ndi zotsatira zowonongeka pakhungu, maso, ndi kupuma.
- Njira zodzitetezera ziyenera kutsatiridwa kuti muwoneke, monga kuvala magolovesi odzitetezera oyenera, magalasi, ndi masks.
- Pewani kukhudzana ndi moto, samalani ndi mpweya wabwino pamene mukusunga, ndipo pewani zinthu zotulutsa okosijeni.
- Mukamagwiritsa ntchito 2,5-dimethylfuran, tsatirani njira zoyenera zotetezera ndikupewa kupuma, kumeza, kapena kukhudza.
