Mawu Oyamba
3-Fluoro-4-nitrotoluene ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha gululi:
Ubwino:
3-fluoro-4-nitrotoluene ndi kristalo wopanda mtundu wolimba wokhala ndi fungo la benzene. Kulemera kwake kwa molekyulu ndi 182.13 g/mol. Pawiri ali otsika solubility ndi sungunuka mu organic solvents monga Mowa ndi ether.
Gwiritsani ntchito:
3-fluoro-4-nitrotoluene makamaka ntchito fluorination zochita mu organic synthesis. Itha kugwiritsidwanso ntchito ku utoto, zokutira organic, zinthu zowoneka bwino, etc.
Njira:
3-fluoro-4-nitrotoluene amakonzedwa m'njira zosiyanasiyana, ndipo tingachipeze powerenga njira akamagwira fluorination wa cyanonitrobenzene. Kukonzekera kwapadera kumakhala kovuta ndipo kumafuna zinthu zina za labotale yamankhwala ndi njira.
Zambiri Zachitetezo:
3-fluoro-4-nitrotoluene ndi mankhwala oopsa. Panthawi ya opaleshoniyo, chisamaliro chiyenera kutengedwa kuti musagwirizane ndi khungu ndi maso, komanso mpweya wokwanira uyenera kuchitidwa. Ngati mutakoka mpweya kapena kumeza, pitani kuchipatala mwamsanga. Pakusungirako, kukhudzana ndi zoyaka, zowonjezera zowonjezera, ndi zina zotero kuyenera kupewedwa, ndikusungidwa pamalo ozizira, owuma. Ndikofunikira kutsatira mosamalitsa malamulo ndi malamulo oyenera ndikusamalira bwino ndikutaya zinyalala. Mukamagwiritsa ntchito kapena kunyamula, chonde onani ndikutsata njira zoyendetsera chitetezo.
