Chemical properties
1) Anhydrous sodium bromide makristasi anonaya mune sodium bromide mhinduro pa51 ℃, uye dihydrate inoumbwa kana tembiricha yadzikira pane 51 ℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Sodium bromide inogona kutsiviwa ne chlorine gasi kuti ipe bromine.
2Br-+Cl2=Br2+2Cl-
3) Sodium bromide inopindirana neconcentrated sulfuric acid kugadzira bromine, kureva kuti, pasi pekuita kweakasimba oxidizing acid, sodium bromide inogona kuve oxidized uye isina bromine.
2NaBr+3H2SO4 (yakadzika) =2NaHSO4+Br2+SO2↑+2H2O
4) Sodium bromide inogona kuita ne dilute sulfuric acid kugadzira hydrogen bromide.
NaBr+H2SO4=HBr+NaHSO4
5) Mumushonga wemvura, sodium bromide inogona kuita nemaoni esirivheri kuita mwenje yeroro yakasimba sirivha bromide.
Br - + Ag + = AgBr kuruboshwe
6) Electrolysis ye sodium bromide munzvimbo yakanyungudutswa kugadzira bromine gasi uye sodium simbi.
2 nabr ine simba = 2 uye + Br2
7) Sodium bromide aqueous solution inogona kugadzira sodium bromate uye hydrogen ne electrolysis.
NaBr + 3H2O= electrolytic NaBrO3 + 3H2↑
8) Organic reactions inogona kuitika, senge iyo huru yekuita kugadzira bromoethane:
NaBr + - H2SO4 + CH2CH2OH ⇌ NaHSO4 + CH3CH2Br + H2O

1) Industrial nzira
Iyo bromine yakawandisa zvishoma inowedzerwa zvakananga kune yakazara sodium hydroxide thermal solution kugadzira musanganiswa webromide uye bromate:
3Br2+6NaOH=5NaBr+NaBrO3+3H2O
Musanganiswa wacho unoputiswa kuti uome, uye zvakasara zvakasara zvakasanganiswa ne toner uye zvinopisa kuderedza bromate kuita bromide:
NaBrO3 = NaBr + 3 c + 3 co nyora
Pakupedzisira, inonyungudutswa mumvura, yozopepetwa uye yakanatswa, yoomeswa pa110 kusvika 130 degrees Celsius.
*Iyi nzira ndiyo yakajairika nzira yekugadzira bromide nebromine uye inowanzo shandiswa muindasitiri.
2) Neutralization nzira
Shandisa sodium bicarbonate seyakagadzirwa: nyungudutsa sodium bicarbonate mumvura, wobva waita neutralize ne 35% -40% hydrobromide kuti uwane sodium bromide solution, inodzorwa uye inotonhodzwa kuti ipere sodium bromide dihydrate. Sefa, nyungudutsa dihydrate nemvura shoma, donhedza bromine mvura kusvikira ruvara rwebromine ruchingobuda muan hydrogen aqueous solution , hydrogen aqueous solution. boil.Pakupisa kwepamusoro, anhydrous crystallization precipitates, uye mushure mekuoma, inotamirwa kune yakaoma uye inochengetwa pa 110 kweawa 1. Inobva yatonhodzwa muomesi ne calcium bromide desiccant kuti iwane anhydrous sodium bromide (reagent grade).
Zvinoita musimboti: HBr+ NAHCO ₃→NaBr+CO2↑+H2O
Iine 40% yealkali yemvura seyakagadzirwa: isa hydrobromide asidhi muhari inokonzeresa, uchitenderedza nguva dzose, zvishoma nezvishoma wedzera 40% mvura alkali solution, neutralize kusvika pH7.5 - 8.0, ita kuti ibudise sodium bromide solution.Sodium bromide solution yaive centrifuged uye yakasefa mu dilute sodium bromide solution solution. of 1. 55°Be or so, centrifugal filtration, filtration into concentrated sodium bromide liquid storage tank.Zvino yakatsikirirwa mucrystallization tank, in the stirring cooling crystallization, and then the crystallization of centrifugal separation, the finished product.Mai doro rinodzoserwa ku dilute sodium bromide liquid storage tank.
Maitiro ekuita: HBr+NaOH→NaBr+H2O
3) Urea kuderedza nzira:
Mune alkali tangi, soda inonyungudutswa mumvura inopisa pakupisa kwe50-60 ° C, uyezve urea.
inowedzerwa kuti iparadze 21 ° Iva mhinduro.Zvino muhari yekudzikisa yekuderedza, zvishoma nezvishoma kuburikidza nebromine, chengetedza kupisa kwekushisa kwe75-85 ° C, kusvika pH ye6-7, ndiko kuti, kusvika kumagumo ekugadzirisa, kumisa bromine nekukurudzira, kuwana sodium bromide solution.
Gadzirisa pH kusvika 2 ne hydrobromic acid, uye wozogadzirisa pH kusvika 6-7 ne urea uye sodium hydroxide kubvisa bromate.Mushonga wacho unopisa kusvika kumota uye saturated solution ye barium bromide inowedzerwa pa pH6 -- 7 kubvisa sulfate.Kana barium munyu wakanyanyisa, dilute sulfuric acid inogona kuwedzerwa kuti ibvise kabhoni, wedzera zvinhu zvekabhoni kuitira kuti ibvise. 4-6 maawa. Mushure mekunge mhinduro yacho yajekeswa, inosefa, inoputika pamhepo yemhepo, uye zvinhu zvepakati zvinozadzwa kakawanda. Rega kudyisa kwemaawa maviri usati waita crystallization. Rongedza pH kusvika 6-7 1 awa isati yaita crystallization.Sodium bromide yakaparadzaniswa uye yakaomeswa mu rotary drum dryer.
Musimboti wekuita: 3Br2+3Na2CO3+ NH2ConH2 =6NaBr+4CO2↑+N2↑+2H2O
