Mawu Oyamba
2-Fluoro-4-bromobenzaldehyde ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha gululi:
Ubwino:
- Maonekedwe: 2-Fluoro-4-bromobenzaldehyde ndi olimba opanda mtundu mpaka chikasu.
- Kusungunuka: Imasungunuka mu zosungunulira za polar monga ethanol ndi methylene chloride.
- Kukhazikika: 2-Fluoro-4-bromobenzaldehyde ndi gulu losakhazikika lomwe limakhudzidwa mosavuta ndi kuwala ndi kutentha ndipo limatha kuwonongeka mosavuta ndi kutentha.
Gwiritsani ntchito:
- Itha kugwiritsidwanso ntchito m'malo monga kaphatikizidwe ka utoto, zopangira, ndi zida zowunikira.
Njira:
2-Fluoro-4-bromobenzaldehyde ikhoza kupangidwa ndi njira zosiyanasiyana, monga:
Mowa wa 2-bromo-4-fluorobenzyl ukhoza kuchitidwa ndi yankho la acidic, yankho lake limatha kuchepetsedwa ndikusungunuka kuti lipeze mankhwala oyeretsedwa.
Itha kupezekanso ndi oxidizing 4-fluorostyrene pamaso pa ethyl bromide.
Zambiri Zachitetezo:
2-Fluoro-4-bromobenzaldehyde ndi organic pawiri yomwe imafuna njira zoyenera zachitetezo ndi njira zomwe ziyenera kutsatiridwa:
- 2-Fluoro-4-bromobenzaldehyde imakwiyitsa ndipo imatha kuwononga maso, khungu, ndi kupuma. Pogwira ntchito, ndikofunikira kuvala zida zodzitetezera zoyenera monga magalasi, magolovesi ndi masks.
- Pewani kutulutsa nthunzi kuchokera mumpweya wake kapena njira zake. Alonda amayenera kuyendetsedwa kapena kugwiritsidwa ntchito pamalo olowera mpweya wabwino.
- Pewani kukhala padzuwa kapena kutentha. Iyenera kusungidwa pamalo ozizira, owuma kuti isakhudzidwe ndi okosijeni.
- Osasakaniza 2-fluoro-4-bromobenzaldehyde ndi oxidizing amphamvu ndipo musathamangire m'madzi kapena malo ena.
Musanagwiritse ntchito 2-fluoro-4-bromobenzaldehyde, onetsetsani kuti mukuwerenga ndikumvetsetsa mapepala okhudzana ndi chitetezo ndi zolemba zogwirira ntchito, ndikutsata njira zoyenera zoyendetsera ndi kutaya.
