1) Indlela yoshishino
Ibromine egqithise kancinci yongezwa ngokuthe ngqo kwisisombululo esishushu sesodium hydroxide ukuvelisa umxube webromide kunye nebromate:
3Br2+6NaOH=5NaBr+NaBrO3+3H2O
Umxube ukhukuliswe ngumphunga ukuze wome, kwaye intsalela eyomeleleyo ixutywe netoner kwaye ifudunyezwe ukunciphisa ibromate ibe yibromide:
NaBrO3 = NaBr + 3 c + 3 co bhala
Ekugqibeleni, iyanyibilika emanzini, emva koko ihluzwe kwaye ikhazimliswe, kwaye yomiswe kwi-110 ukuya kwi-130 degrees celsius.
*Le ndlela yindlela eqhelekileyo yokulungisa ibromide ngebromine kwaye isetyenziswa ngokubanzi kushishino.
2)Indlela yokungathathi hlangothi
Sebenzisa i-sodium bicarbonate njengento ekrwada: nyibilikisa i-sodium bicarbonate emanzini, kwaye emva koko uyithintele nge-35% -40% ye-hydrobromide ukuze ufumane isisombululo se-sodium bromide, ephonswayo kwaye ipholiswe ukuze iqhube i-sodium bromide dihydrate.Filter, nyibilikisa i-dihydrate kunye nomlinganiselo omncinci wamanzi, uwise amanzi e-bromine de umbala we-bromine ubonakale nje kwisisombululo se-hydrogen, i-aqueous, i-decoloral, i-hydrogen sulfure, i-design ye-aqueous, i-hydrogen, i-aqulour, i-hydrogen, i-design, i-aqueous solution Ubilise.Ngobushushu obuphezulu, i-anhydrous crystallization precipitates, kwaye emva kokumisa, idluliselwa kwi-dryer kwaye igcinwe kwi-110 ngeyure ye-1. Emva koko ipholile kwi-dryer kunye ne-calcium bromide desiccant ukufumana i-anhydrous sodium bromide (i-reagent grade).
Umgaqo-siseko wokusabela: HBr+ NAHCO ₃→NaBr+CO2↑+H2O
Nge-40% yealkali yolwelo njengento ekrwada: beka i-hydrobromide acid kwimbiza yokusabela, phantsi kokuvuselela rhoqo, ngokucotha ukongeza i-40% yesisombululo solwelo sealkali, ingathathi hlangothi ukuya kwi-pH7.5 --8.0, isabela ukuvelisa isisombululo se-sodium bromide.Isisombululo se-sodium bromide sahluzwa kwi-dilute yesodium bromide isisombululo setanki yokugcina. ye-1. 55 ° Yiba okanye kunjalo, ukuhluzwa kwe-centrifugal, ukuhluzwa kwi-sodium bromide yokugcina ulwelo itanki yokugcina.Emva koko icinezelwe kwitanki yecrystallization, kwi-crystallization epholileyo yokupholisa, kwaye emva koko i-crystallization yokwahlula i-centrifugal, imveliso egqityiweyo.Utywala lomama bubuyiselwa kwi-tank ye-sodium bromide yokugcina ulwelo.
Umgaqo-siseko wokusabela: HBr+NaOH→NaBr+H2O
3)Indlela yokunciphisa urea:
Kwitanki ye-alkali, i-soda iyachithwa emanzini ashushu kwiqondo lokushisa lama-50-60 ° C, kwaye emva koko urea.
idityaniswe ukunyibilikisa i-21 ° Yiba isisombululo.Emva koko kwibhodwe lokuphendula lokunciphisa, ngokukhawuleza nge-bromine, lawula ukushisa kwe-reaction ye-75-85 °C, ukuya kwi-pH ye-6-7, oko kukuthi, ukufikelela ekupheleni kokuphendula, ukumisa i-bromine kunye nokuvuselela, ukufumana isisombululo se-sodium bromide.
Lungisa i-pH kwi-2 kunye ne-hydrobromic acid, kwaye emva koko ulungise i-pH kwi-6-7 kunye ne-urea kunye ne-sodium hydroxide ukususa i-bromate.Isisombululo sishushu kwi-thumba kunye nesisombululo esigcweleyo se-barium bromide songezwa kwi-pH6 --7 ukususa i-sulfate.Ukuba ityuwa ye-barium igqithise, i-dilute sulfuric acid inokongezwa emva kokususa i-carbon dioxide kunye ne-activated indawo yokuphendula. 4-6 iiyure. Emva kokuba isisombululo sicaciswe, siyahluzwa, sikhutshwe kwi-atmospheric pressure, kwaye izinto eziphakathi zizaliswe ngamaxesha amaninzi. Yeka ukutya kwiiyure ze-2 ngaphambi kwe-crystallization.Lungisa i-pH kwi-6-7 i-1 iyure ngaphambi kwe-crystallization.I-bromide ye-sodium yahlulwa kwaye yomiswa kwi-drum dryer.
Umgaqo-siseko wokusabela: 3Br2+3Na2CO3+ NH2ConH2 =6NaBr+4CO2↑+N2↑+2H2O
