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

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

umgangatho
Idatha ethembekileyo
Umgubo obomvu wekristale. Indawo yokunyibilika imalunga nama-200°C. Inyibilika kancinci emanzini, ethanol, inyibilika kwiasidi. Ugqabhuko-dubulo lunokwenzeka xa luvezwe kubushushu, ludibana nedangatye elivulekileyo, ubushushu obuphezulu, ukukhuhlana, ukungcangcazela, kunye nefuthe. Xa utshisiwe ukhupha umsi oyityhefu nocaphukisayo. Ukudibanisa nee-oxidants kunokwenza imixube eqhumayo.

Indlela
Idatha ethembekileyo
I-Hydrazine sulfate yanqunyanyiswa emanzini ashushu, i-potassium acetate yongezwa, ipholile emva kokubilisa, i-ethanol yongezwa, i-solids yahluzwa, kwaye i-filtrate ihlanjwe nge-ethanol. I-2,4-= i-nitrophenyl ethanol yongezwa kwisisombululo se-hydrazine esingentla, kwaye i-2,4-= i-nitrophenylhydrazine yafunyanwa ngokucoca, ukuhlamba, ukumisa, kunye nokugxilwa kwe-filtrate.

sebenzisa
Idatha ethembekileyo
I-reagent ye-chromogenic yokumisela i-aldehydes kunye ne-ketones nge-chromatography encinci. Isetyenziswa njenge-reagent ye-ultraviolet derivatization ye-aldehydes kunye nee-ketones kwi-organic synthesis kunye nokuveliswa kweziqhushumbisi.

ukhuseleko
Idatha ethembekileyo
impuku yomlomo LDso: 654mg/kg. Iyacaphukisa emehlweni kunye nolusu. Ivuselela ulusu. Le mveliso ifakwe emzimbeni, enokubangela i-methemoglobinemia kunye ne-cyanosis. Gcina kwindawo epholileyo nengena umoya. Zigcine kude nomlilo kunye nemithombo yobushushu. Ubushushu bendawo yokugcina impahla akufunekanga budlule kwi-30°C. Khusela ilanga elithe ngqo. Gcina isitya sivalwe ngokuqinileyo. Ngenxa yezizathu zokhuseleko, isoloko imanziswa kwaye igqithiswe ngamanzi angekho ngaphantsi kwe-25% ngexesha lokugcinwa kunye nokuthutha. Kufuneka igcinwe ngokwahlukileyo kwi-oxidants kunye ne-acids. Musa ukuxuba ukugcinwa kunye nokuthutha.
