Waxyaabaha kiimikada
1) Kiristaalo anhydrous sodium bromide ah ayaa ku soo da'aya xalka sodium bromide ee 51℃, fuuq-baxa waxa la sameeyaa marka heerkulku ka hooseeyo 51℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Sodium bromide waxaa lagu bedeli karaa gaaska chlorine si loo siiyo bromine.
2Br-+Cl2=Br2+2Cl-
3) Sodium bromide waxay la falgashaa sulfuric acid xoog leh si ay u dhaliso bromine, taas oo ah, iyada oo la raacayo ficilka aashitada oksaydhiyaha ee xooggan, sodium bromide waa la oksaydhsan karaa oo ka madax banaan bromine.
2NaBr+3H2SO4 (ku urursan) =2NaHSO4+Br2+SO2↑+2H2O
4) Sodium bromide waxay la falgali kartaa sulfuric acid si ay u soo saarto hydrogen bromide.
NaBr+H2SO4=HBr+NaHSO4
5) Xalka aqueous, sodium bromide waxay ka falcelin kartaa ions lacag ah si ay u sameeyaan bromide qalin ah oo huruud ah oo khafiif ah.
Br - + Ag + = AgBr bidix
6) Electrolysis of sodium bromide ee gobolka dhalaalay si loo dhaliyo gaaska bromine iyo birta sodium.
2 nabr tamar leh = 2 na + Br2
7) Sodium bromide xal aqueous waxay dhalin kartaa bromate sodium iyo hydrogen by electrolysis.
NaBr + 3H2O= NaBrO3 + 3H2↑
8) Dareen-celinta dabiiciga ah ayaa dhici karta, sida falcelinta ugu weyn ee samaynta bromoethane:
NaBr + - H2SO4 + CH2CH2OH ⇌ NaHSO4 + CH3CH2Br + H2O

1) Habka warshadaha
Bromine-ka yar ee xad-dhaafka ah ayaa si toos ah loogu daraa xal kuleyliyaha saturated sodium hydroxide si loo dhaliyo isku dhafka bromide iyo bromate:
3Br2+6NaOH=5NaBr+NaBrO3+3H2O
Isku darka ayaa la uumi baxa si ay u engegaan, iyo haraaga adag ee ka soo baxa waxaa lagu qasi karaa toner oo la kululeeyaa si loo yareeyo bromate si bromide:
NaBrO3 = NaBr + 3 c + 3 co qor
Ugu dambeyntii, waxaa lagu milmaa biyaha, ka dibna la sifeeyaa oo la miiriyaa, oo la qalajiyo 110 ilaa 130 darajo Celsius.
* Habkani waa habka guud ee bromide lagu diyaariyo bromine waxaana guud ahaan loo adeegsadaa warshadaha.
2) Habka dhexdhexaadinta
Isticmaal sodium bicarbonate sida walxo ceeriin ah: milmi bicarbonate sodium biyo, ka dibna dhexdhexaadin leh 35% -40% hydrobromide si aad u hesho xal sodium bromide, kaas oo la isku koobay oo la qaboojiyey si ay u soo dejiso sodium bromide dihydrate.Filter, milmi fuuq-baxa qadar yar oo biyo ah, hoos u dhig biyaha bromine ilaa midabka bromine kaliya u muuqda in uu keeno xal hydrogen ah. Heerkulka sare, kristallization anhydrous ayaa soo da'aya, ka dib marka la qalajiyo, waxaa loo wareejiyaa qalajiyaha waxaana lagu hayaa 110 ilaa 1 saac. Kadibna waxaa lagu qaboojiyaa qalajiyaha qalajiyaha calcium bromide si loo helo sodium bromide anhydrous (darajada reagent).
Mabda'a falcelinta: HBr+ NAHCO ₃→NaBr+CO2↑+H2O
Iyada oo 40% alkali dareere ah sida alaabta ceeriin: gelin hydrobromide acid galay dheriga falcelinta, hoos walaaqaya joogto ah, si tartiib ah ku dar 40% xal alkali dareere ah, dhexdhexaadin si pH7.5 -- 8.0, falcelinta si ay u soo saaraan sodium bromide solution.The sodium bromide xal ayaa centrifuged iyo sifeeyo galay badhanka sodium taangiga bromide taangiga si gaar ah u quudin, fiirsashada 1 jeer kaydinta taangiga bromide gaar ah. cufnaanta 1. 55 ° Noqo ama wax la mid ah, shaandhaynta centrifugal, shaandhaynta galay uruursan sodium bromide taangiga dareere dareere ah Ka dibna riixay galay taangiga crystallization, in crystallization walaaqaya qaboojinta, ka dibna crystallization ee kala soocidda centrifugal, alaabta la dhammeeyey, khamriga hooyada waxaa lagu soo celiyaa haanta kaydinta dareere sodium bromide walaaqi.
Mabda'a falcelinta: HBr+NaOH→NaBr+H2O
3) Habka dhimista urea:
Taangiga alkali, soodhada waxaa lagu milmaa biyo kulul heerkul ah 50-60 ° C, ka dibna HOL
waxaa lagu daraa si ay u milaan 21 ° Noqo xal. Ka dibna geli dheriga falcelinta dhimista, si tartiib ah iyada oo loo marayo bromine, xakamee heerkulka falcelinta ee 75-85 ° C, pH ee 6-7, taas oo ah, si loo gaaro dhamaadka falcelinta, jooji bromine iyo walaaq, hel xal sodium bromide.
Ku hagaaji pH ilaa 2 oo leh hydrobromic acid, ka dibna ku hagaaji pH ilaa 6-7 oo leh HOL iyo sodium hydroxide si aad uga saarto bromate. Xalka waxaa lagu kululeeyaa karkari iyo xal buuxa oo barium bromide ah ayaa lagu daraa pH6 - 7 si looga saaro sulfate. 4-6 saacadood. Ka dib markii xalka la caddeeyo, waa la sifeeyaa, uumi baxa cadaadiska atmospheric, iyo walxaha dhexdhexaadka ah ayaa la buuxiyaa dhowr jeer. Jooji quudinta 2 saacadood ka hor inta aan la kicin. Isku hagaajin pH ilaa 6-7 1 saac kahor crystallization. Soodhiyam bromide waa la kala soocay waxaana lagu qallajiyey qalajiyaha durbaanka rotary.
Mabda'a falcelinta: 3Br2+3Na2CO3+ NH2ConH2 =6NaBr+4CO2↑+N2↑+2H2O
