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

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

izinga
Idatha ethembekile
I-crystalline powder ebomvu. Indawo yokuncibilika icishe ibe ngu-200°C. Incibilika kancane emanzini, i-ethanol, inyibilika ku-asidi. Ukuqhuma kungenzeka lapho kuvezwe ukushisa, ukuthintana nelangabi elivulekile, ukushisa okuphezulu, ukushwibeka, ukudlidliza, kanye nomthelela. Uma ushisiwe, ukhipha intuthu enobuthi futhi ecasulayo. Ukuxuba nama-oxidants kungakha izingxube eziqhumayo.

Indlela
Idatha ethembekile
IHydrazine sulfate yayilengiswa emanzini ashisayo, i-potassium acetate yengezwe, ipholile ngemva kokubilisa, i-ethanol yengezwa, okuqinile kwahlungwa, futhi i-filtrate yagezwa nge-ethanol. I-2,4-= i-nitrophenyl ethanol yengezwe kusixazululo se-hydrazine esingenhla, futhi i-2,4-= i-nitrophenylhydrazine itholwe ngokuhlunga, ukugeza, ukomisa, nokugxila kwe-filtrate.

sebenzisa
Idatha ethembekile
Kuyi-reagent ye-chromogenic yokunqunywa kwe-aldehydes nama-ketone nge-chromatography yongqimba oluncane. Isetshenziswa njenge-reagent ye-ultraviolet derivatization yama-aldehyde nama-ketone ekukhiqizeni okuphilayo kanye nokukhiqizwa kweziqhumane.

ezokuphepha
Idatha ethembekile
irat ngomlomo LDso: 654mg/kg. Iyacasula emehlweni nasesikhumbeni. Iyazwela esikhumbeni. Lo mkhiqizo udonswa emzimbeni, ongabangela i-methemoglobinemia ne-cyanosis. Gcina endaweni epholile, engenisa umoya. Gcina kude nomlilo nemithombo yokushisa. Izinga lokushisa le-warehouse akufanele lidlule ku-30 ​​° C. Vikela elangeni eliqondile. Gcina isitsha sivalwe ngokuqinile. Ngenxa yezizathu zokuphepha, ivame ukumanziswa futhi idluliswe ngamanzi angekho ngaphansi kwama-25% ngesikhathi sokugcinwa nokuhamba. Kufanele igcinwe ngokuhlukana nama-oxidants nama-asidi. Ungahlanganisi isitoreji nezinto zokuhamba.
