Ukubukeka | Impushana emhlophe |
Ukuminyana | 2.257 g/cm3, okuqinile |
Iphoyinti lokuncibilika | 308 °C (586 °F; 581 K) |
Iphuzu elibilayo | 380 °C (716 °F; 653 K) iyabola |
Ukuncibilika emanzini | 73 g/100 mL (0 °C) 91.2 g/100 mL (25 °C) 180 g/100 mL (100 °C) |
Ukuncibilika | Incibilika kakhulu ku-ammonia, i-hydrazine encibilikayo otshwaleni incibilika kancane ku-pyridine ayincibiliki ku-acetone |
I-sodium nitrite (NaNO2) usawoti we-inorganic okhiqizwa ama-nitrite ions kanye ne-sodium ions' reaction.I-sodium nitrite i-hydrolyzing kalula futhi inyibilika emanzini kanye ne-ammonia ewuketshezi.Isixazululo saso esinamanzi sine-alkaline, i-PH icishe ibe ngu-9;futhi iyancibilika kancane kuzincibilikisi eziphilayo njenge-ethanol, i-methanol ne-ether.I-oxidizer eqinile futhi inempahla yokunciphisa futhi.Uma ivezwa emoyeni, i-Sodium Nitrite izokwenziwa i-oxidized kancane kancane, futhi iphenduke ibe yi-nitrate ye-sodium phezulu.Igesi ye-nitrogen dioxide ensundu ikhishwa ngaphansi kwesimo se-asidi ebuthakathaka.Ukuthintana nezinto eziphilayo noma i-ejenti enciphisayo kuzoholela ekuqhumeni noma ekushiseni, ngaphezu kwalokho, kudedele igesi ye-nitrogen oxide enobuthi futhi ecasulayo.I-Sodium Nitrite ingabuye ifakwe i-oxidized ngama-oxidizing agents aqinile, ikakhulukazi usawoti we-ammonium, njenge-ammonium nitrate, i-ammonium persulfate, njll.Uma ishiselwa ku-320 ℃ noma ngaphezulu, i-Sodium Nitrite izobola ibe umoya-mpilo, i-nitrogen oxide ne-sodium oxide.Lapho uthintana nezinto eziphilayo, kulula ukuvutha nokuqhuma.
Izicelo:
Ukuhlaziywa kweChromatographic: Ukuhlaziywa kwe-drip kusetshenziselwa ukunquma i-mercury, i-potassium ne-chlorate.
Ama-reagents e-Diazotization: i-Nitrosation reagent;Ukuhlaziya umhlabathi;Ukunqunywa kwe-serum bilirubin ekuhlolweni kokusebenza kwesibindi.
I-bleaching agent ye-silika nelineni, i-ejenti yokwelapha ukushisa kwensimbi;insimbi corrosion inhibitor;I-Cyanide poisoning antidote, ama-reagents okuhlaziya aselabhorethri.Endaweni yokudla, isetshenziswa njengama-ejenti e-chromophores lapho kucutshungulwa imikhiqizo yenyama, kanye nama-antimicrobial agents, ama-preservatives.Iphinde ibe nezinhlelo zokusebenza ekufakweni kwe-bleaching, electroplating kanye nokwelashwa kwensimbi.
Ukunakwa kwesitoreji: i-sodium nitrite kufanele igcinwe endaweni yokushisa ephansi, eyomile futhi enomoya.Iminyango namafasitela kuqinile ukuvimbela ukukhanya kwelanga okuqondile.Ingagcinwa esitokisini namanye ama-nitrate ngaphandle kwe-ammonium nitrate, kodwa ihlukaniswe nezinto eziphilayo, izinto ezivuthayo, i-ejenti enciphisayo kanye nomthombo womlilo.
