O mea tau vailaau
1) Anhydrous sodium bromide tioata e to'a i le vaifofo sodium bromide i le 51 ℃, ma dihydrate e faia pe a maualalo le vevela nai lo le 51 ℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) E mafai ona suia le sodium bromide i le kasa chlorine e maua ai le bromine.
2Br-+Cl2=Br2+2Cl-
3) O le sodium bromide e tali atu i le acid sulfuric concentrated e maua ai le bromine, o lona uiga, i lalo o le gaioiga o le malosi oxidizing acid, o le sodium bromide e mafai ona oxidized ma saoloto mai bromine.
2NaBr+3H2SO4 (concentrate) =2NaHSO4+Br2+SO2↑+2H2O
4) O le sodium bromide e mafai ona tali atu i le sulfuric acid fa'afefeteina e maua ai le hydrogen bromide.
NaBr+H2SO4=HBr+NaHSO4
5) I vaifofo vai, e mafai ona tali atu le sodium bromide ma ion siliva e fausia ai le bromide siliva malosi samasama.
Br - + Ag + = AgBr agavale
6) Electrolysis o le sodium bromide i le tulaga liusua e gaosia bromine kasa ma sodium uamea.
2 nabr malosi = 2 na + Br2
7) Sodium bromide vai vaifofo e mafai ona gaosia sodium bromate ma hydrogen e electrolysis.
NaBr + 3H2O= electrolytic NaBrO3 + 3H2↑
8) E mafai ona tupu ni fa'agaioiga fa'aletino, e pei o le tali autu e fai ai le bromoethane:
NaBr + - H2SO4 + CH2CH2OH ⇌ NaHSO4 + CH3CH2Br + H2O

1) Alamanuia auala
O le bromine teisi tele e fa'aopoopo sa'o i le vai fa'amama o le sodium hydroxide e maua ai se fa'afefiloi o le bromide ma le bromate:
3Br2+6NaOH=5NaBr+NaBrO3+3H2O
O le faʻafefiloi e faʻamamago e faʻagogo, ma o le mea e maua ai le toega malo e faʻafefiloi ma le toner ma faʻamafanafana e faʻaitiitia ai le bromate i le bromide:
NaBrO3 = NaBr + 3 c + 3 co tusi
Mulimuli ane, e faʻafefeteina i le vai, ona faʻamama ma faʻamaʻa, ma faʻamago i le 110 i le 130 tikeri Celsius.
*O lenei metotia o le auala lautele o le saunia o le bromide e bromine ma e masani ona faʻaaogaina i alamanuia.
2) auala fa'a'ese'ese
Faʻaaoga le sodium bicarbonate e pei o mea mata: faʻamavae le sodium bicarbonate i le vai, ona faʻafefe ai lea i le 35% -40% hydrobromide e maua ai le vaifofo o le sodium bromide, lea e faʻafefeteina ma faʻamafanafanaina e faʻafefe ai le sodium bromide dihydrate.Filter, faʻamaʻape le dihydrate ma sina vai itiiti, faʻafefe vai bromine seia oʻo ina foliga mai le lanu o le sulfide o le sulfide ma le hydrogen. i se vevela.I le maualuga o le vevela, faʻafefeteina tioata anhydrous, ma a maeʻa ona faʻagogo, e tuʻuina atu i le mea faʻagogo ma tausia i le 110 mo le 1 itula. Ona faʻamafanafanaina lea i totonu o se faʻamago ma le calcium bromide desiccant e maua ai le sodium bromide anhydrous (vaega regent).
Fa'atonuga tali: HBr+ NAHCO ₃→NaBr+CO2↑+H2O
Faatasi ai ma le 40% alkali vai e pei o mea mata: tuu hydrobromide acid i totonu o le ulo tali, i lalo o le faʻavevesi faifaipea, faʻaopoopo lemu 40% vai vaifofo alkali, neutralize i pH7.5 -- 8.0, tali atu e maua ai le sodium bromide solution.O le sodium bromide solution sa centrifuged ma faamama i totonu o le dilute sodium bromide solution solution tank.Then i totonu o le tane e teu ai vaifofo evaporation2. o le 1. 55 ° Ia pe, centrifugal filtration, filtration i totonu concentrated sodium bromide vai tane teuina. Ona fetaomi atu lea i totonu o le tane crystallization, i le faagaeeina cooling crystallization, ona sosoo ai lea ma le crystallization o le vavaeeseina centrifugal, ua toe foi atu le oloa gaosi oloa.The tina i le dilute sodium bromide vai vai.
Fa'atonuga tali: HBr+NaOH→NaBr+H2O
3) Urea faʻaitiitia auala:
I totonu o le tane alkali, o le soda e faʻamavaeina i totonu o le vai vevela i le vevela o le 50-60 °C, ona sosoo ai lea ma le urea.
faʻaopoopo e faʻamavae 21 ° Be vaifofo. Ona i totonu o le faʻaitiitiga tali faʻafefete, faʻagesegese e ala i le bromine, pulea le vevela o le 75-85 °C, i le pH o le 6-7, o lona uiga, e oʻo atu i le pito o le tali, taofi le bromine ma faʻamalosi, maua le vaifofo sodium bromide.
Fetuunai le pH i le 2 ma le hydrobromic acid, ona fetuunai lea o le pH i le 6-7 ma le urea ma le sodium hydroxide e aveese ai le bromate.O le vaifofo e vevela i se vevela ma se vaifofo tumu o le barium bromide e faaopoopo i le pH6 -- 7 e aveese ai le sulfate. Afai o le masima barium e tele naua, e mafai ona faaopoopo le sulfuric sulfuric dilute ina ua uma ona toe fa'afo'i le mea e toe fa'afo'i ai. 4-6 itula. A maeʻa ona faʻamalamalamaina le vaifofo, e faʻamamāina, faʻamama i le mamafa o le ea, ma faʻatumu mea faʻavaitaimi i ni nai taimi. Taofi le fafagaina mo le 2 itula aʻo leʻi faʻamago. Fetuunaʻi le pH i le 6-7 1 itula aʻo leʻi faʻamaʻa. Na vavae ese le sodium bromide ma faʻagogo i totonu o se masini faʻagogo rotary.
Fa'avae o le tali atu: 3Br2+3Na2CO3+ NH2ConH2 =6NaBr+4CO2↑+N2↑+2H2O
