Waxyaabaha kiimikada ah
1) Kalluumeysiga sodium bromide kristaliyuhu wuxuu da'ayaa xalka sodium bromide ee 51 ℃, dihydrate-na waa la sameeyaa marka heerkulku ka hooseeyo 51 ℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Sodium bromide waxaa lagu badali karaa gaaska koloriin si loo siiyo bromine.
2Br- + Cl2 = Br2 + 2Cl-
3) Sodium bromide waxay la falgashaa sulfuric acid urursan si loo abuuro bromine, taas oo ah, hoosta ficilka oksijiinta adag, sodium bromide waa la oksijiyeyn karaa lagana nadiifin karaa bromine.
2NaBr + 3H2SO4 (urursan) = 2NaHSO4 + Br2 + SO2 ↑ + 2H2O
4) Sodium bromide waxay ku falcelin kartaa milix sulfuric acid si loo soo saaro hydrogen bromide.
NaBr + H2SO4 = HBr + NaHSO4
5) Xalka aqueous, sodium bromide waxay ku falcelin kartaa ions lacag ah si ay u sameysmaan bromide qalin adag oo huruud ah.
Br - + Ag + = AgBr ayaa tagay
6) Electrolysis-ka sodium bromide oo ku jirta xaalad dhalaal ah si loo soo saaro gaaska bromine iyo birta sodium.
2 tamarta nabr = 2 na + Br2
7) Sodium bromide aqueous solution wuxuu abuuri karaa sodium bromate iyo hydrogen by elektrolysis.
NaBr + 3H2O = elektroonikada NaBrO3 + 3H2 ↑
8) Dareen-celinta jirka ayaa dhici karta, sida fal-celinta ugu weyn ee lagu sameeyo bromoethane:
NaBr + - H2SO4 + CH2CH2OH ⇌ NaHSO4 + CH3CH2Br + H2O

1) Habka warshadaha
Bromine-ka waxoogaa xad-dhaafka ah ayaa si toos ah loogu daraa xalka kuleylka ee sodium hydroxide ee kuleylka ah si loo sameeyo isku-dar ah bromide iyo bromate:
3Br2 + 6NaOH = 5NaBr + NaBrO3 + 3H2O
Isku darka waa la uumiyaa si uu u qallalo, hadhaaga adag ee ka dhashana waxaa lagu qasaa toner waana la kululeeyaa si loo yareeyo bromate-ka iyo bromide
NaBrO3 = NaBr + 3 c + 3 co wax qor
Ugu dambeyntiina, waxaa lagu kala diraa biyo, ka dib waa la sifeeyaa oo la caddeeya, waxaana lagu qalajiyaa 110 illaa 130 darajo Celsius.
* Habkani waa habka guud ee bromide loogu diyaariyo bromine waxaana guud ahaan loo adeegsadaa warshadaha.
2) Habka dhexdhexaadinta
U isticmaal sodium bicarbonate alaab ceeriin ah: ku milmi sodium bicarbonate biyo, ka dibna ku kala nadiifi 35% -40% hydrobromide si aad u hesho sodium bromide xal, kaas oo cufan oo la qaboojiyey si loo sii daayo sodium bromide dihydrate. biyaha, tuura biyaha bromine ilaa midabka bromine uu uun soo muuqdo. Kulayl, ku qurxiya xalka aqueous ee hydrogen sulfide, oo karkari. heerkulka sare, sunta crystallization anhydrous, ka dib marka la qalajiyo, waxaa loo wareejiyaa qalajiyaha iyo waxaa lagu hayaa 110 ilaa 1 saac Ka dibna waxaa lagu qaboojiyaa qalajiyaha leh kaalshiyam bromide qallajiye ah si loo helo anhydrous sodium bromide (reagent grade).
Mabda'a falcelinta: HBr + NAHCO ₃ → NaBr + CO2 ↑ + H2O
40% oo ah alkali dareere ah maadada ceyriin ah: ku dar hydrobromide acid dheriga falcelinta, walaaq joogto ah, si tartiib ah ugu dar 40% xalka alkali ee dareeraha ah, dhexdhexaad u noqo pH7.5 - 8.0, falceliso soo saarida xalka sodium bromide. taangiga uumiga uumiga, quudinta dhexdhexaadka ah 1-2 jeer, ilaa culeyska gaarka ah ee 1. 55 ° Be ama sidaas, kala sifeynta bartamaha, kala sifeynta taangiyada sodium bromide ee kaydinta dareeraha ah Kadibna lagu cadaadiyey taangiga crystallization, ee kicinta qaboojinta kicinta, ka dibna crystallization ee kala-soocida kala-soocida, badeecada la soo gabagabeeyay. Khamriga hooyada ayaa lagu soo celiyay haanta dareeraha sodium bromide ee kaydinta.
Mabda'a falcelinta: HBr + NaOH → NaBr + H2O
3) Habka yareynta Urea:
Taangiga alkali, soodhaha ayaa lagu kala diraa biyo kulul heerkulkiisu yahay 50-60 ° C, ka dibna urea
waxaa lagu daraa in lagu kala diro 21 ° Be xal. Kadibna dheriga yareynta falcelinta, tartiib tartiib ah iyada oo loo marayo bromine, xakamee heerkulka falcelinta ee 75-85 ° C, illaa pH of 6-7, taas oo ah, in la gaaro dhamaadka jawaab celinta, jooji brominka iyo kicinta, hel xalka sodium bromide.
Isku hagaaji pH ilaa 2 oo leh hydrobromic acid, ka dibna pH ilaa 6-7 ku hagaaji urea iyo sodium hydroxide si aad uga saarto bromate. Xalka waa la kululeynayaa karkar iyo xalka miisaanka leh ee barium bromide ayaa lagu darayaa pH6 - 7 si looga saaro sulfate Haddii milixda bariumku badan tahay, dilid sulfuric acid ayaa lagu dari karaa si loo baabi'iyo.Karboonka firfircoon ee walxaha ficil-celinta kadib markaad ka saarto wasakhda, oo dhig 4-6 saacadood. Kadib marka xalka la cadeeyo, waa la sifeeyaa, waxaa lagu uumi karaa cadaadiska cimilada, walxaha dhexena waa la buuxiyaa dhowr jeer. Jooji quudinta ilaa 2 saacadood kahor intaanad crystallization ka dhigin pH ilaa 6-7 1 saac ka hor inta aan la dhagaxayn. Sodium bromide waa lakala soocay waxaana lagu qalajiyay mashiinka durbaanka wareega.
