Sodium nitrite (NaNO2) is an inorganic munyu inogadzirwa ne nitrite ions uye sodium ions' reaction.Sodium nitrite iri nyore hydrolyzing uye soluble mumvura uye liquid ammonia.Mhinduro yayo ine aqueous ndeye alkaline, iyo PH inenge 9;uye inonyungudika zvishoma muorganic solvents senge ethanol, methanol uye ether.Iyo yakasimba oxidizer uye ine reductive pfuma zvakare.Kana yaiswa kumhepo, Sodium Nitrite inozoitwa oxidized zvishoma nezvishoma, uye inoshanduka kuita sodium nitrate pamusoro.Brown nitrogen dioxide gasi inosunungurwa pasi pemamiriro asina simba easidhi.Kubata ne organic zvinhu kana kuderedza mumiririri kunotungamira kuputika kana kupisa, uyezve, kuburitsa muchetura uye inoshatirisa nitrogen oxide gasi.Sodium Nitrite inogonawo kuve neoxidized neakasimba oxidizing agents, kunyanya ammonium munyu, seammonium nitrate, ammonium persulfate, nezvimwewo, iyo inogona kupindirana pamwe chete kuti ibudise kupisa kwakanyanya pakupisa kwemazuva ose, zvichiita kuti zvinhu zvinopisa zvipise.Kana yapiswa kusvika 320 ℃ kana pamusoro, Sodium Nitrite inoora kuita oxygen, nitrogen oxide uye sodium oxide.Kana uchisangana ne organic matter, zviri nyore kupisa uye kuputika.
Applications:
Chromatographic analysis: Drip analysis inoshandiswa kuona mercury, potassium uye chlorate.
Diazotization reagents: Nitrosation reagent;Kuongorora kwevhu;Kutsunga kweserum bilirubin muyedzo yekushanda kwechiropa.
Bleaching agent yesilika uye yerineni, simbi yekupisa kupisa mumiririri;simbi corrosion inhibitor;Cyanide poisoning antidote, laboratory analytical reagents.Munzvimbo yekudya, inoshandiswa se chromophores 'agents pakugadzira zvigadzirwa zvenyama, pamwe neantimicrobial agents, preservatives.Iyo ine zvakare maapplication mu bleaching, electroplating uye simbi kurapwa.
Chengetedzo yekutarisira: sodium nitrite inofanirwa kuchengetwa mune yakaderera tembiricha, yakaoma uye inofefetera imba yekuchengetera.Magonhi neMahwindo zvakasimba kudzivirira zuva rakananga.Inogona kuchengetwa mustock nemamwe ma nitrate kunze kweammonium nitrate, asi yakaparadzaniswa kubva kune organic matter, inopisa zvinhu, inoderedza agent uye moto sosi.
