Lik'hemik'hale
1) Likristale tse nang le anhydrous sodium bromide li kenella ka har'a tharollo ea sodium bromide ho 51 ℃, 'me dihydrate e thehoa ha mocheso o le tlase ho 51 ℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Bromide ea sodium e ka nkeloa sebaka ke khase ea chlorine ho fa bromine.
2Br- + Cl2 = Br2 + 2Cl-
3) Sodium bromide e itšoara ka asiti ea sulfuric e kenelletseng ho hlahisa bromine, ke hore, tlasa tšebetso ea asiti e matla ea oxidizing, bromide ea sodium e ka ts'oaetsoa ebile e lokolohile bromine.
2NaBr + 3H2SO4 (e tsepamisitsoeng) = 2NaHSO4 + Br2 + SO2 2 + 2H2O
4) Sodium bromide e ka sebetsana le hlapolla asiti ea sulfuric ho hlahisa hydrogen bromide.
NaBr + H2SO4 = HBr + NaHSO4
5) Ka tharollo ea metsi, bromide ea sodium e ka sebetsana le li-ion tsa silevera ho theha bromide ea silevera e bosehla bo bobebe.
Br - + Ag + = AgBr e setseng
6) Electrolysis ea sodium bromide e maemong a qhibilihisitsoeng ho hlahisa khase ea bromine le tšepe ea sodium.
2 matlafatso nabr = 2 na + Br2
7) Tharollo ea metsi a sodium bromide e ka hlahisa bromate ea sodium le hydrogen ka electrolysis.
NaBr + 3H2O = NaBrO3 ea motlakase + 3H2 electr
8) Liketso tsa 'mele li ka hlaha, joalo ka karabelo e kholo ea ho etsa bromoethane:
NaBr + - H2SO4 + CH2CH2OH ⇌ NaHSO4 + CH3CH2Br + H2O

1) Mokhoa oa indasteri
Bromine e fetelletseng hanyane e eketsoa ka kotloloho ho tharollo e chesang ea sodium hydroxide ho hlahisa motsoako oa bromide le bromate:
3Br2 + 6NaOH = 5NaBr + NaBrO3 + 3H2O
Motsoako o fetoha mouoane hore o ome, 'me masala a tiileng a hlahisoang a kopantsoe le toner ebe oa futhumatsoa ho fokotsa bromate hore e be bromide:
NaBrO3 = NaBr + 3 c + 3 co ngola
Qetellong, e qhibilihisoa ka metsing, e ntan'o tlhotliloeng ebe e entsoe likristale, ebe ea omisoa ka likhato tse 110 ho isa ho tse 130 tsa Celsius.
Mokhoa ona ke mokhoa o akaretsang oa ho lokisa bromide ka bromine mme o sebelisoa khafetsa indastering.
2) Mokhoa oa ho se nke lehlakore
Sebelisa bicarbonate ea sodium e le lisebelisoa tse tala: qhala bicarbonate ea sodium ka metsing, ebe oe fokotsa ka 35% -40% ea hydrobromide ho fumana tharollo ea sodium bromide, e khutsufalitsoeng le ho pholisoa ho fokotsa sodium bromide dihydrate Metsi, lahlela metsi a bromine ho fihlela 'mala oa bromine o hlaha feela. e bolokoa ka 110 hora e le 'ngoe ebe e pholisoa ka har'a se omisitsoeng ka calcium bromide desiccant ho fumana anhydrous sodium bromide (reagent grade).

Molao-motheo oa karabelo: HBr + NaOH → NaBr + H2O
3) Mokhoa oa phokotso ea Urea:
Ka tankeng ea alkali, soda e qhibiliha metsing a chesang ka mocheso oa 50-60 ° C, ebe urea
E kenyelletsoa ho qhala 21 ° Be tharollo. Ebe ka pitseng ea phokotso ea karabelo, butle butle ka bromine, laola mocheso oa karabelo oa 75-85 ° C, ho pH ea 6-7, ke hore, ho fihlela pheletso, emisa bromine mme e hlohlelletse, fumana tharollo ea sodium bromide.
Fetola pH ho ea ho 2 ka asiti ea hydrobromic, 'me u fetole pH ho ea ho 6-7 ka urea le sodium hydroxide ho tlosa bromate. Tharollo e futhumetse ho pheha mme tharollo e khotsofatsang ea barium bromide e eketsoa ho pH6 - 7 ho tlosa sulfate. Haeba letsoai la barium le le ngata haholo, hlapolla asiti ea sulfuric e ka eketsoa ho eketsa khabone e sebelisitsoeng ho lintho tse itšireletsang kamora ho tlosa litšila, ebe o li beha lihora tse 4-6. Kamora hore tharollo e hlakisoe, ea tlhotliloeng, ea fetoha mouoane ka lebaka la khatello ea sepakapaka, ebe lintho tse mahareng li tlatsoa makhetlo a 'maloa. Khaotsa ho fepa lihora tse 2 pele ho khanya. Fetola pH ho isa ho 6-7 hora pele ho crystallization. Bromide ea sodium e ile ea aroloa le ho omisoa ka har'a sesebelisoa sa moqomo oa rotary.
Molao-motheo oa karabelo: 3Br2 + 3Na2CO3 + NH2ConH2 = 6NaBr + 4CO2 ↑ + N2 ↑ + 2H2O
