2,4-Dinitrophenylhydrazine(CAS#119-26-6)

2,4-Dinitrophenylhydrazine(CAS#119-26-6) yambitsani

khalidwe
Zambiri zodalirika
Red crystalline ufa. Malo osungunuka ndi pafupifupi 200 ° C. Kusungunuka pang'ono m'madzi, Mowa, kusungunuka mu asidi. Kuphulika kumatha kuchitika pa kutentha, kukhudzana ndi lawi lotseguka, kutentha kwakukulu, kukangana, kugwedezeka, ndi kukhudzidwa. Akawotchedwa, amatulutsa utsi wapoizoni komanso wokwiyitsa. Kusakaniza ndi okosijeni kumatha kupanga zosakaniza zophulika.

Njira
Zambiri zodalirika
Hydrazine sulphate inaimitsidwa m'madzi otentha, potaziyamu acetate inawonjezeredwa, itakhazikika pambuyo pa kuwira, ethanol inawonjezeredwa, zolimba zimasefedwa, ndipo filtrate inatsukidwa ndi ethanol. 2,4-= nitrophenyl ethanol inawonjezeredwa ku yankho lapamwamba la hydrazine, ndipo 2,4-= nitrophenylhydrazine inapezedwa mwa kusefera, kutsuka, kuyanika, ndi kusefera.

ntchito
Zambiri zodalirika
Ndi chromogenic reagent kuti adziwe aldehydes ndi ketoni ndi woonda wosanjikiza chromatography. Amagwiritsidwa ntchito ngati ultraviolet derivatization reagent for aldehydes ndi ketones mu organic synthesis ndi kupanga zophulika.

chitetezo
Zambiri zodalirika
makoswe pakamwa LDSo: 654mg/kg. Zimakwiyitsa maso ndi khungu. Zimakhudza khungu. Mankhwalawa amalowetsedwa m'thupi, zomwe zingayambitse methemoglobinemia ndi cyanosis. Sungani m'nyumba yosungiramo zinthu zoziziritsa kukhosi komanso mpweya wabwino. Khalani kutali ndi gwero la moto ndi kutentha. Kutentha kwa nyumba yosungiramo zinthu sikuyenera kupitirira 30 ° C. Dzitetezeni ku dzuwa. Sungani chidebecho chosindikizidwa mwamphamvu. Pazifukwa zachitetezo, nthawi zambiri imanyowetsedwa ndikudutsa madzi osachepera 25% panthawi yosungira ndikuyenda. Iyenera kusungidwa mosiyana ndi ma okosijeni ndi zidulo. Osasakaniza zosungirako ndi zoyendera.
