Mawu Oyamba
2,5-Difluorobenzaldehyde. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, njira zopangira ndi chitetezo:
Ubwino:
2,5-Difluorobenzaldehyde ndi madzi achikasu owala osawoneka bwino okhala ndi chizindikiro chowotcha kwambiri, fungo lonunkhira bwino lomwe limatentha kwambiri. Izo sizisungunuka m'madzi koma zimatha kusungunuka mu zosungunulira za organic monga ethanol, toluene, ndi zina.
Gwiritsani ntchito:
2,5-Difluorobenzaldehyde ili ndi machitidwe osiyanasiyana mu kaphatikizidwe ka organic. Itha kugwiritsidwa ntchito ngati kalambulabwalo wa kaphatikizidwe ka mankhwala onunkhira, zotumphukira za paraphthalenedione, ndi mamolekyu a bioactive. Itha kugwiritsidwanso ntchito popanga ma organometallic complexes, zokutira zogwira ntchito kwambiri ndi utoto.
Njira:
2,5-difluorobenzaldehyde imatha kukonzedwa ndi zomwe benzaldehyde ndi hydrogen fluoride. Izi zimachitika nthawi zambiri pansi pa acidic ndipo zitha kutheka pogwiritsa ntchito hydrofluoric acid ngati gwero la hydrogen fluoride.
Zambiri Zachitetezo:
Kusamala kofunikira kuyenera kuchitidwa pogwira 2,5-difluorobenzaldehyde. Imakhala ndi zonyansa pakhungu, maso ndi kupuma. Magalasi oteteza mankhwala, magolovesi ndi zovala zodzitchinjiriza ziyenera kuvala ndipo kukhudzana mwachindunji kuyenera kupewedwa. Zikakulowa m'maso kapena pakhungu, muzimutsuka nthawi yomweyo ndi madzi ambiri ndipo pitani kuchipatala mwachangu. Panthawi yogwira ntchito, ziyenera kusungidwa kutali ndi kumene zimayaka moto ndikupewa utsi ndi nthunzi kuti zipewe moto ndi kuphulika.
Ichi ndichidule chachidule cha katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 2,5-difluorobenzaldehyde. Ngati pakufunika, onetsetsani kuti mwamvetsetsa ndikutsata malamulo otetezedwa a labotale ndi malangizo musanagwire kapena kugwiritsa ntchito.
