Sodium nitrite (NaNO2) ndi mchere wopangidwa ndi nitrite ions ndi sodium ions' reaction.sodium nitrite mosavuta hydrolyzing ndi sungunuka m'madzi ndi madzi ammonia.Njira yake yamadzimadzi ndi yamchere, PH ili pafupi 9;ndipo imasungunuka pang'ono mu zosungunulira za organic monga ethanol, methanol ndi ether.Ndi oxidizer amphamvu ndipo ali ndi katundu reductive komanso.Mukakumana ndi mlengalenga, sodium Nitrite imasinthidwa pang'onopang'ono, ndikusandulika kukhala sodium nitrate pamwamba.Mpweya wa nayitrogeni wakuda wa nayitrogeni umatulutsidwa pansi pa acidity yofooka.Kulumikizana ndi zinthu zakuthupi kapena zochepetsera kumayambitsa kuphulika kapena kuyaka, kutulutsa mpweya wapoizoni komanso wokwiyitsa wa nitrogen oxide.Sodium Nitrite imathanso kukhala oxidized ndi amphamvu oxidizing wothandizira, makamaka ammonium mchere, monga ammonium nitrate, ammonium persulfate, etc., amene angagwirizane wina ndi mzake kutulutsa kutentha kwambiri pa kutentha yachibadwa, kutsogolera zipangizo kuyaka kuwotcha.Ikatenthedwa mpaka 320 ℃ kapena kupitilira apo, sodium Nitrite imatha kuwola kukhala oxygen, nitrogen oxide ndi sodium oxide.Mukalumikizana ndi zinthu zakuthupi, ndizosavuta kuyaka ndikuphulika.
Mapulogalamu:
Kusanthula kwa Chromatographic: Kusanthula kwa drip kumagwiritsidwa ntchito kudziwa mercury, potaziyamu ndi klorate.
Diazotization reagents: Nitrosation reagent;Kusanthula nthaka;Kutsimikiza kwa seramu bilirubin pakuyesa ntchito ya chiwindi.
Bleaching wothandizira silika ndi bafuta, zitsulo kutentha mankhwala wothandizira;zitsulo dzimbiri inhibitor;Mankhwala ophera poizoni a cyanide, ma laboratory analytical reagents.M'dera lazakudya, amagwiritsidwa ntchito ngati othandizira a chromophores pokonza nyama, komanso antimicrobial agents, preservatives.Ilinso ndi ntchito poyeretsa, electroplating ndi chithandizo chachitsulo.
Kusungirako chidwi: sodium nitrite ziyenera kusungidwa kutentha otsika, youma ndi mpweya wokwanira yosungiramo.Zitseko ndi Mawindo ali olimba kuti ateteze kuwala kwa dzuwa.Ikhoza kusungidwa mu katundu ndi ma nitrate ena osati ammonium nitrate, koma olekanitsidwa ndi zinthu zamoyo, zinthu zoyaka moto, kuchepetsa wothandizira ndi gwero lamoto.
