Mawu Oyamba
3,5-difluorophenylhydrazine hydrochloride ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, kagwiritsidwe ntchito, njira yopangira ndi chidziwitso cha chitetezo:
Katundu: Imasungunuka m'madzi ndi zosungunulira zina monga ethanol, methanol. Ndi chinthu chofooka cha acidic chomwe chimagwirizana ndi alkalis.
Gwiritsani ntchito:
3,5-difluorophenylhydrazine hydrochloride nthawi zambiri amagwiritsidwa ntchito ngati kuchepetsa ndi activator mu organic synthesis. Itha kugwiritsidwa ntchito powonjezera zochita, kuchepetsa zinthu zachilengedwe monga ma ketoni, aldehydes, ma ketoni onunkhira, ndi zina.
Njira:
3,5-Difluorophenylhydrazine hydrochloride imatha kupezeka ndi zomwe hydroquinone ndi 2-chloro-1,3,5-trifluorobenzene. Nthawi zambiri, hydroquinone imakhudzidwa ndi kuchuluka kwa 2-chloro-1,3,5-trifluorobenzene pansi pamikhalidwe yamchere kuti ipeze 3,5-difluorophenylhydrazine. Pochitapo kanthu ndi hydrogen chloride, 3,5-difluorophenylhydrazine hydrochloride ikhoza kupezeka.
Zambiri Zachitetezo:
3,5-Difluorophenylhydrazine hydrochloride ndi mankhwala omwe amagwiritsidwa ntchito nthawi zambiri m'ma laboratories ndi kupanga mafakitale. Ndondomeko zoyenera ziyenera kutsatiridwa panthawi ya ndondomekoyi, ndipo zipangizo zodzitetezera zoyenera monga magolovesi, magalasi otetezera chitetezo, ndi malaya a labu ziyenera kuvala. Sichiwopsezo chochepa, koma chiyenera kupewedwa kuti zisakhudze khungu, maso, ndi kupuma. Ngati akhudzidwa, m'pofunika kuti muzimutsuka mwamsanga ndi madzi ambiri ndikupita kuchipatala mwamsanga. Panthawi yosungiramo, ziyenera kusungidwa kutali ndi magwero a moto ndi zipangizo zoyaka moto, ndikusungidwa pamalo owuma, omwe ali ndi mpweya wabwino.
