Mawu Oyamba
2,4-Difluorophenylhydrazine hydrochloride ndi organic pawiri ndi mankhwala formula C6H6F2N2 · HCl. Zotsatirazi ndikulongosola mwatsatanetsatane za chikhalidwe chake, ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Mawonekedwe: Olimba akristalo opanda mtundu
-Posungunuka: 151-153°C
Kulemera kwa mamolekyulu: 188.59
-Kusungunuka: Kusungunuka m'madzi ndi zosungunulira zina, monga ethanol ndi chloroform
Gwiritsani ntchito:
2,4-Difluorophenylhydrazine hydrochloride imagwiritsidwa ntchito makamaka ngati kuchepetsa ndi nitrogen-containing reagent mu organic synthesis. Imatha kuchitapo kanthu ndi zinthu zina zopangira organic kupanga zotumphukira za hydrazine, monga kaphatikizidwe ka quinones, kapena kaphatikizidwe kazinthu zina za nayitrogeni heterocyclic.
Njira Yokonzekera:
2,4-Difluorophenylhydrazine hydrochloride nthawi zambiri imatha kukonzedwa ndi phenylhydrazine ndi 2,4-difluorobenzaldehyde. Zomwe zimachitika nthawi zambiri zimaphatikizira kuchita zomwe zimachitikira m'njira yoyambira ndikuwonjezera pang'onopang'ono hydrochloric acid ndi mpweya wotsatira wa mankhwala monga mchere wa hydrochloride.
Zambiri Zachitetezo:
- 2,4-Difluorophenylhydrazine hydrochloride ndi chinthu choyipa, chonde samalani kuti musapume mpweya, kulowa kapena kukhudzana ndi khungu ndi maso.
-Valani zida zodzitetezera zoyenera monga magolovesi, zopumira ndi magalasi mukamagwiritsa ntchito ndikugwira ntchito.
-Chonde sungani chosindikizidwa ndikupewa kukhudzana ndi mpweya, chinyezi komanso kuwala.
-chonde tsatirani njira zachitetezo cha labotale, pewani moto ndi kuyatsa pafupi ndi ntchitoyo.
