Nā waiwai kemika
1) Anhydrous sodium bromide crystals precipitate i loko o ka sodium bromide solution ma 51 ℃, a hoʻokumu ʻia ka dihydrate ke emi ka mahana ma mua o 51 ℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Hiki ke pani ʻia ka sodium bromide e ke kinoea chlorine e hāʻawi i ka bromine.
2Br-+Cl2=Br2+2Cl-
3) Hoʻopili ka sodium bromide me ka sulfuric acid concentrated e hoʻohua i ka bromine, ʻo ia hoʻi, ma lalo o ka hana o ka waikawa oxidizing ikaika, hiki ke hoʻoheheʻe ʻia ka sodium bromide a manuahi mai ka bromine.
2NaBr+3H2SO4 (concentrated) =2NaHSO4+Br2+SO2↑+2H2O
4) Hiki i ka sodium bromide ke hana me ka dilute sulfuric acid e hana i ka hydrogen bromide.
NaBr+H2SO4=HBr+NaHSO4
5) I loko o ka wai wai, hiki i ka sodium bromide ke hana me nā ion kālā e hana i ka bromide kālā paʻa melemele māmā.
Br - + Ag + = AgBr hema
6) Electrolysis o ka sodium bromide i loko o ka moku i hoʻoheheʻe ʻia e hana i ke kinoea bromine a me ka metala sodium.
2 nabr ikaika = 2 na + Br2
7) Hiki i ka sodium bromide aqueous solution ke hana i ka sodium bromate a me ka hydrogen ma o ka electrolysis.

1) Keʻano hana hana
Hoʻohui pololei ʻia ka bromine i ʻoi aku ka nui i ka hopena wela o ka sodium hydroxide e hoʻohua i ka hui ʻana o ka bromide a me ka bromate:
3Br2+6NaOH=5NaBr+NaBrO3+3H2O
Hoʻopau ʻia ka hui ʻana a maloʻo, a hui pū ʻia ke koena paʻa me ka toner a hoʻomehana ʻia e hoʻemi i ka bromate i bromide:
NaBrO3 = NaBr + 3 c + 3 co kakau
ʻO ka hope, hoʻoheheʻe ʻia i ka wai, a laila kānana a crystallized, a maloʻo ma 110 a 130 degere Celsius.
* ʻO kēia kaʻina hana maʻamau o ka hoʻomākaukau ʻana i ka bromide e ka bromine a hoʻohana mau ʻia i ka ʻoihana.
2) Keʻano o ka neutralization
E hoʻohana i ka sodium bicarbonate e like me ka mea maka: e hoʻoheheʻe i ka sodium bicarbonate i ka wai, a laila e hoʻokaʻawale iā ia me 35% -40% hydrobromide e kiʻi i ka solution sodium bromide, i hoʻopaʻa ʻia a hoʻomaha ʻia e hoʻoheheʻe i ka sodium bromide dihydrate. i ka boil.Ma ke kiʻekiʻe wela, anhydrous crystallization precipitates, a ma hope o ka hoʻomaloʻoʻana, ua hoʻoneʻe 'ia i ka dryer a mālama 'ia ma 110 no 1 hola. It ua cooled i loko o ka mea maloʻo me ka calcium bromide desiccant e loaa anhydrous sodium bromide (reagent grade).
Kumukānāwai pane: HBr+ NAHCO ₃→NaBr+CO2↑+H2O
Me ka 40% wai alkali e like me ka mea maka: e kau i ka waika hydrobromide i loko o ka ipu hao, ma lalo o ka hoʻoulu ʻana mau, e hoʻohui mālie i ka 40% wai alkali solution, neutralize i ka pH7.5 -- 8.0, e hana i ka hopena sodium bromide. o 1. 55 ° Be a pela, centrifugal kānana, kānana i loko o concentrated sodium bromide wai waihona pahu.A laila kaomi i loko o ka crystallization pahu, i ka hoʻouluulu cooling crystallization, a laila, i ka crystallization o centrifugal kaawale, ka pau product.The makuahine waiʻona ua hoʻihoʻi 'ia i ka dilute sodium bromide wai waihona pahu.
Manaʻo pane: HBr+NaOH→NaBr+H2O
3) Keʻano ho'ēmi Urea:
I loko o ka pahu alkali, ua hoʻoheheʻe ʻia ka soda i ka wai wela ma kahi mahana o 50-60 °C, a laila urea.
Hoʻohui ʻia e hoʻoheheʻe 21 ° Be solution. A laila i loko o ka hoʻohaʻahaʻa pane ʻana i ka ipuhao, mālie ma o bromine, e hoʻomalu i ka mahana hopena o 75-85 °C, i ka pH o 6-7, ʻo ia hoʻi, e hiki i ka hopena o ka hopena, hoʻōki i ka bromine a me ka hoʻoulu ʻana, e kiʻi i ka solution sodium bromide.
Hoʻololi i ka pH i ka 2 me ka waika hydrobromic, a laila hoʻololi i ka pH i 6-7 me ka urea a me ka sodium hydroxide e wehe i ka bromate. Hoʻomaʻamaʻa ʻia ka hopena i kahi ʻeha a hoʻohui ʻia kahi hopena saturated o ka barium bromide i ka pH6 -- 7 e wehe i ka sulfate. 4-6 hola. Ma hope o ka hoʻomaʻamaʻa ʻana o ka hopena, kānana ʻia, hoʻoheheʻe ʻia i ke kaomi ea, a hoʻopiha ʻia ka mea waena i nā manawa he nui. E ho'ōki i ka hānai ʻana no 2 mau hola ma mua o ka crystallization. E hoʻoponopono i ka pH i ka 6-7 1 hola ma mua o ka crystallization. Ua hoʻokaʻawale ʻia ka sodium bromide a maloʻo i loko o kahi pahu maloʻo rotary.
Kumu o ka pane: 3Br2+3Na2CO3+ NH2ConH2 =6NaBr+4CO2↑+N2↑+2H2O
