1) Indlela yezimboni
I-bromine eyeqile kancane yengezwa ngokuqondile kusisombululo esishisayo se-sodium hydroxide esishisayo ukuze kukhiqizwe ingxube ye-bromide ne-bromate:
3Br2+6NaOH=5NaBr+NaBrO3+3H2O
Ingxube iyahwamuka ukuze yome, futhi okusele okuqinile okubangelwayo kuxutshwa ne-toner futhi kushiswe ukuze kuncishiswe i-bromate ibe yi-bromide:
NaBrO3 = NaBr + 3 c + 3 co bhala
Ekugcineni, iyancibilika emanzini, bese ihlungwa futhi ifakwe amakristalu, bese yomiswa ku-110 kuya ku-130 degrees Celsius.
*Le ndlela iyindlela ejwayelekile yokulungisa i-bromide nge-bromine futhi ivame ukusetshenziswa embonini.
2)Indlela yokungathathi hlangothi
Sebenzisa i-sodium bicarbonate njengento eluhlaza: chaza i-sodium bicarbonate emanzini, bese uyinciphisa nge-35% -40% ye-hydrobromide ukuze uthole isisombululo se-sodium bromide, esifinyezwa futhi sipholiswe ukuze kuncibilike i-sodium bromide dihydrate.Hlunga, chaza i-dihydrate ngamanzi amancane, uphonsa amanzi e-bromine kuze kube yilapho kuvela umbala we-bromine ku-anhydrogen aqueous solution kanye ne-hydrogen aque afis solution. ubilise.Emazingeni okushisa aphezulu, i-anhydrous crystallization precipitates, futhi ngemva kokumiswa, idluliselwa kumshini wokomisa futhi igcinwe ku-110 ihora le-1. Ibe ipholiswa endaweni eyomile nge-calcium bromide desiccant ukuze ithole i-anhydrous sodium bromide (i-reagent grade).
Isimiso sokusabela: HBr+ NAHCO ₃→NaBr+CO2↑+H2O
Ngo-40% we-alkali ewuketshezi njengempahla eluhlaza: faka i-hydrobromide acid embizeni yokusabela, ngaphansi kokunyakaziswa njalo, kancane kancane engeza u-40% wesisombululo se-alkali esiwuketshezi, nciphisa ku-pH7.5 --8.0, asabele ukukhiqiza isixazululo se-sodium bromide. kokungu-1. 55°Yiba noma kunjalo, ukuhlunga okumaphakathi, ukuhluzwa ethangini lokugcina uketshezi lwe-sodium bromide.Bese kucindezelwa ethangini le-crystallization, ku-crystallization yokupholisa enyakazayo, bese kuba icrystallization yokuhlukaniswa kwe-centrifugal, umkhiqizo osuphelile.Utshwala bomama bubuyiselwa ethangini lokugcina uketshezi lwe-sodium bromide.
Isimiso sokusabela: HBr+NaOH→NaBr+H2O
3) Indlela yokunciphisa urea:
Ethangini le-alkali, i-soda iyancibilika emanzini ashisayo ekushiseni kwama-50-60 ° C, bese kuba yi-urea.
yengezwa ukuze incibilikise i-21 ° Yiba isisombululo.Bese ungene ebhodweni lokuphendula lokunciphisa, kancane kancane nge-bromine, lawula izinga lokushisa lokuphendula lika-75-85 °C, ku-pH ye-6-7, okungukuthi, ukufinyelela ekupheleni kokusabela, misa i-bromine futhi uvuselele, thola isisombululo se-sodium bromide.
Lungisa i-pH ibe ngu-2 nge-hydrobromic acid, bese ulungisa i-pH ibe ngu-6-7 nge-urea ne-sodium hydroxide ukuze ukhiphe i-bromate.Isixazululo sishisiswe sibe ngamathumba futhi isixazululo esigcwele se-barium bromide singezwa ku-pH6 -- 7 ukuze kukhishwe i-sulfate.Uma usawoti we-barium udlulele, hlambulula i-sulfuric acid ingafakwa ukuze ikhiphe indawo ye-carbon, i-activate ukuze isuse indawo. Amahora angu-4-6. Ngemva kokuba ikhambi licaciswe, liyahlungwa, lihwamuke ekucindezelweni komkhathi, futhi impahla ephakathi igcwaliswa izikhathi eziningana. Yeka ukuphakela amahora angu-2 ngaphambi kwecrystallization.Lungisa i-pH ibe ngu-6-7 1 ihora ngaphambi kokucwebezela.I-sodium bromide yahlukaniswa futhi yomiswa kumshini wokomisa imigqomo ojikelezayo.
Isimiso sokusabela: 3Br2+3Na2CO3+ NH2ConH2 =6NaBr+4CO2↑+N2↑+2H2O
