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

ubuziranenge
Amakuru yizewe
Ifu itukura. Ingingo yo gushonga igera kuri 200 ° C. Gushonga buhoro mumazi, Ethanol, gushonga muri aside. Ibisasu birashobora kubaho mugihe uhuye nubushyuhe, guhura numuriro ufunguye, ubushyuhe bwinshi, guterana amagambo, kunyeganyega, ningaruka. Iyo itwitse, isohora imyotsi yubumara kandi irakaza. Kuvanga na okiside birashobora gukora imvange ziturika.

Uburyo
Amakuru yizewe
Hydrazine sulfate yahagaritswe mu mazi ashyushye, hongerwaho acetate ya potasiyumu, ikonjesha nyuma yo gutekwa, Ethanol yongerwamo, ibishishwa birayungurura, kandi filtrate yogejwe na Ethanol. 2,4- = nitrophenyl etanol yongewe kumuti wa hydrazine yavuzwe haruguru, naho 2,4- = nitrophenylhydrazine yabonetse mukuyungurura, gukaraba, kumisha, no kuyungurura.

Koresha
Amakuru yizewe
Ni chromogenic reagent yo kumenya aldehydes na ketone ukoresheje chromatografi yoroheje. Ikoreshwa nka ultraviolet derivatisation reagent ya aldehydes na ketone muguhuza ibinyabuzima no gukora ibisasu.

umutekano
Amakuru yizewe
imbeba umunwa LDso: 654mg / kg. Birakaza amaso n'uruhu. Irimo gukangura uruhu. Iki gicuruzwa cyinjiye mu mubiri, gishobora gutera methemoglobinemia na cyanose. Ubike mu bubiko bukonje, buhumeka. Irinde umuriro nubushyuhe. Ubushyuhe bwububiko ntibugomba kurenga 30 ° C. Irinde izuba ryinshi. Komeza ikintu gifunze neza. Kubwimpamvu z'umutekano, akenshi iba itose kandi igashiramo amazi atarenze 25% mugihe cyo kubika no gutwara. Igomba kubikwa ukwayo na okiside na aside. Ntukavange ububiko no gutwara.
