Iimpawu zemichiza
1) Amakhemikhali e-sodium bromide anhydrous ayanyibilika kwisisombululo se-sodium bromide kwi-51 ℃, kwaye i-dihydrate yenziwa xa iqondo lobushushu lingaphantsi kwama-51 ℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Isodium bromide inokutshintshwa yichlorine yegesi ukunika bromine.
2Br- + Cl2 = Br2 + 2Cl-
I-3) Isodium bromide iphendula nge-sulfuric acid egxile ekuveliseni i-bromine, oko kukuthi, phantsi kwesenzo se-asidi eyomeleleyo, i-sodium bromide inokudityaniswa kwaye ingenasimahla kwi-bromine.
2NaBr + 3H2SO4 (kugxilwe) = 2NaHSO4 + Br2 + SO2 2 + 2H2O
4) Isodium bromide inokusabela ngokudibanisa isalfure acid ukuvelisa ihydrogen bromide.
NaBr + H2SO4 = HBr + NaHSO4
5) Kwisisombululo esinamandla, isodium bromide inokusabela ngeeon zesilivere ukuze zenze ukukhanya okuluhlaza okwesibhakabhaka.
Br - + Ag + = AgBr ngasekhohlo
I-6) i-Electrolysis yesodium bromide ekwimeko etyhidiweyo ukuvelisa igesi yebromine kunye nesinyithi yesodiyam.
2 amandlaabr = 2 na + Br2
I-7) Isisombululo se-sodium bromide esinamandla sinokuvelisa isodium bromate kunye ne-hydrogen nge-electrolysis.
NaBr + 3H2O = i-NaBrO3 yombane + 3H2 electr
8) Ukuphendulwa kwezinto eziphilayo kunokwenzeka, njengempendulo ephambili yokwenza i-bromoethane:
NaBr + - H2SO4 + CH2CH2OH, NaHSO4 + CH3CH2Br + H2O

Iindlela zokulungiselela

1) Indlela yoshishino
I-bromine ecekeceke kancinci yongezwa ngokuthe ngqo kwisisombululo esishushu se-sodium hydroxide yokuvelisa umxube we-bromide kunye ne-bromate:
3Br2 + 6NaOH = 5NaBr + NaBrO3 + 3H2O
Umxube uyanyuka umphunga ukuze wome, kwaye intsalela eqinileyo edityanisiweyo ixutywe ne toner kunye nokufudunyezwa ukunciphisa i-bromate ukuya kwi-bromide:
NaBrO3 = NaBr + 3 c + 3 co bhala
Okokugqibela, inyibilikiswa emanzini, emva koko icocwe kwaye idityaniswe, kwaye yomiswe kwi-110 ukuya kwi-130 degrees Celsius.
* Le ndlela yindlela eqhelekileyo yokulungiselela i-bromide nge-bromine kwaye isetyenziswa ngokubanzi kumzi mveliso.
2) Indlela yokungathathi cala
Sebenzisa i-sodium bicarbonate njengezinto ezingavuthiyo: nyibilikisa isodium bicarbonate emanzini, emva koko uyiyekise nge-35% -40% yehydrobromide ukufumana isisombululo se-bromide yesisombululo, esixineneyo nesipholileyo ukucutha isodium bromide dihydrate. Amanzi, yehla amanzi e-bromine de umbala we-bromine uvele nje, ishushu, isisombululo kwisisombululo samanzi se-hydrogen sulfide, kwaye uzise emathunjini. kubushushu obuphezulu, i-anhydrous crystallization precipitates, kwaye emva kokomisa, idluliselwe kwisomisi kwaye igcinwe kwi-110 ngeyure e-1.
Umgaqo wokuphendula: HBr + NAHCO ₃ → NaBr + CO2 ↑ + H2O
Nge-40% ye-alkali engamanzi njengezinto ezingafunekiyo: beka i-hydrobromide acid embizeni yokuphendula, phantsi kokunyanzelwa rhoqo, kongeza kancinci i-40% yesisombululo se-alkali, ungene kwi-pH7.5 -8.0, usabele ukuvelisa isisombululo se-bromide yesodium. I-centrifuged kwaye icocwe kwitanki yokugcina isisombululo se-bromide yesisombululo. Emva koko kungena itanki yokuxinana komphunga, isondlo esiphakathi amaxesha angama-1-2, kumxhuzulane othile we-1. Emva koko ucinezelwe kwitanki ye-crystallization, kwi-crystallization yokupholisa evuselelayo, emva koko i-crystallization yokwahlukana kwe-centrifugal, imveliso egqityiweyo.Umama wotywala ubuyiselwa kwitanki yokugcina isodium bromide.
Umgaqo wokuphendula: HBr + NaOH → NaBr + H2O
3) indlela yokunciphisa i-Urea:
Kwitanki yealkali, isoda inyibilikiswa emanzini ashushu kubushushu obungama-50-60 ° C, emva koko urea
Yongezwa ukuba inyibilike i-21 ° Yiba sisisombululo, emva koko kwisitya sokuphendula, ngokuthe chu nge-bromine, lawula ubushushu bokusabela kwe-75-85 ° C, kwi-pH ye-6-7, oko kukuthi, ukufikelela esiphelweni sokuphendula, yeka i-bromine kwaye uxhokonxe, fumana isisombululo se-bromide yesodium.
Lungisa i-pH ukuya kwi-2 ene-hydrobromic acid, emva koko uhlengahlengise i-pH ukuya kwi-6-7 kunye ne-urea kunye ne-sodium hydroxide ukuze ususe i-bromate. Ukuba ityuwa ye-barium igqithile, kungongezwa i-acid ye-sulfuric ukususa.Yongeza ikhabhoni kwinto yokuphendula emva kokususa ukungcola, uyibeke kangangeeyure eziyi-4-6. Emva kokuba isisombululo sicacisiwe, siyacocwa, senziwe ngumphunga kuxinzelelo lomoya, kwaye izinto eziphakathi zizaliswa amatyeli aliqela. Yeka ukondla iiyure ezi-2 ngaphambi kokufakwa kwekristale.Lungisa i-pH ukuya kwi-6-7 iyure e-1 ngaphambi kwe-crystallization.I-bromide yesodium yahlulwa yoma kwi-rotary drum dryer.
Umgaqo wokuphendula: 3Br2 + 3Na2CO3 + NH2ConH2 = 6NaBr + 4CO2 ↑ + N2 ↑ + 2H2O
