Nā Pono Kino
1) Nā Pono: ʻAno ʻole cubic aniani a keʻokeʻo granular pauka. He ʻaʻohe honi, paʻakai a ʻawaʻawa iki.
2) Ka nui (g / mL, 25 ° C): 3.203;
3) Wahi hoʻoheʻe (℃): 755;
4) Kahi hoʻolapalapa (° C, kaomi lewa): 1390;
5) Refractive index: 1.6412;
6) Kahi kiko (° C): 1390
7) Palehua: maʻalahi ka hoʻoheheʻe ʻia i ka wai (ʻo ka hoʻoheheʻe ʻia he 90.5g / 100ml wai ma 20 ° C, ʻo ka solubility he 121g / 100ml wai ma 100 ° C), kūleʻa a maʻalahi hoʻi ka hopena aqueous. acetonitrile, ʻākika waikawa.
8) Kaomi mahu (806 ° C): 1mmHg.
Nā waiwai kemika
1) Anhydrous sodium bromide crystals piʻi i ka hopena sodium bromide ma 51 ℃, a hana ʻia ka dihydrate ke haʻahaʻa ka mahana ma mua o 51 ℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Hiki ke pani ʻia ʻo Sodium bromide e ka gasolina chlorine e hāʻawi i ka bromine.
2Br- + Cl2 = Br2 + 2Cl-
3) hana ʻo Sodium bromide me ka waikawa sulfuric paʻa e hana i ka bromine, ʻo ia hoʻi, ma lalo o ka hana o ka waikawa oxidizing ikaika, hiki ke oxidized a me ka manuahi o bromine mai ka bromine.
2NaBr + 3H2SO4 (hoʻohui) = 2NaHSO4 + Br2 + SO2 ↑ + 2H2O
4) Sodium bromide hiki ke hana me ka dilute sulfuric acid e hana i ka hydrogen bromide.
NaBr + H2SO4 = HBr + NaHSO4
5) I loko o ka wai aqueous solution, hiki i ka sodium bromide ke hana me nā ion kala e hana i ka bromide kālā melemele mālamalama.
Br - + Ag + = AgBr hema
6) Electrolysis o ka sodium bromide i ka moku i hoʻoheheʻe ʻia e hana i ka gas bromine a me ka metala sodium.
2 ikaika nabr = 2 na + Br2
7) hiki i ka sodium Sodoma bromide aqueous solution ke hoʻoulu i ka sodium bromate a me ka hydrogen e ka electrolysis.
NaBr + 3H2O = electrolytic NaBrO3 + 3H2 ↑

Nā Papahana Hoʻomākaukau

1) Ke ʻano hana
Hoʻohui pololei ʻia ka bromine liʻiliʻi i ka hopena sodium sodium hydroxide saturated e hana i kahi hui o bromide a me bromate.
3Br2 + 6NaOH = 5NaBr + NaBrO3 + 3H2O
Hoʻopau ʻia ka hui ʻana e maloʻo, a ʻo ka hopena i koe i hui ʻia me ka toner a hoʻomehana ʻia e hoʻoliʻiliʻi i ka bromate i bromide:
NaBrO3 = NaBr + 3 c + 3 co kākau
ʻO ka hope, ua hoʻoheheʻe ʻia i ka wai, a laila kānana a crystallized, a hoʻomaloʻo ʻia ma 110 a 130 mau kekelē Celsius.
* ʻO kēia hana ke ʻano maʻamau o ka hoʻomākaukau ʻana i ka bromide e bromine a hoʻohana mau ʻia i ka ʻoihana.
2) Ke ʻano neutrization
E hoʻohana i ka sodium bicarbonate ma ke ʻano he mea waiwai: hoʻoheheʻe i ka sodium bicarbonate i ka wai, a laila neenee ia me 35% -40% hydrobromide e loaʻa ai ka hopena sodium bromide, i hoʻopili ʻia a hoʻalili ʻia e hoʻoulu i ka sodium bromide dihydrate. o ka wai, e hoʻolei i ka wai bromine a hiki i ke ʻano o ke kala o ka bromine. Hahana, decolor i kahi wai wai o ka hydrogen sulfide, a hoʻolapalapa. Ma kahi kiʻekiʻe o ke ana wela, piʻi ka crystallization anhydrous, a ma hope o ka hoʻomaloʻo ʻana, hoʻohuli ʻia i ka maloʻo mālama ʻia ma 110 no hoʻokahi hola. Hoʻomaʻalili ʻia ia i kahi mea hoʻomaloʻo me ka waipona bromide desiccant e loaʻa ai ka anhydrous sodium bromide (reagent grade).
Ke kumu hoʻohālikelike: HBr + NAHCO ₃ → NaBr + CO2 ↑ + H2O
Me 40% wai alkali e like me nā mea maka: kau i ka waikawa hydrobromide i loko o ka ipu i loko o ka ipu, ma lalo o ka hoʻoulu mau ʻana, e hoʻonui mālie i ka 40% wai ʻākana wai, hoʻopau i ka PH7.5 - 8.0, hana e hana i ka hopena sodium bromide. centrifuged a kānana ʻia i loko o ka dilute sodium bromide solution storage tank. A laila i loko o ka pahu wai e hoʻoliʻiliʻi ai, ʻai waena waena 1-2 mau manawa, i ka umekaumaha kikoʻī o 1. 55 ° E a i ʻole, centrifugal filtration, filtration into concentrated sodium bromide wai mālama wai pahu wai A laila kaomi ʻia i loko o ka pahu crystallization, i ka crystallization hoʻoluʻu hoʻohuihui, a laila ka crystallization o ka hoʻokaʻawale centrifugal, ka huahana i hoʻopau ʻia. Ua hoʻihoʻi ʻia ka wai inu makuahine i ka pahu dilime sodium bromide wai mālama wai.
Ke kumu hoʻohālikelike: HBr + NaOH → NaBr + H2O
3) Urea hōʻemi hana:
I loko o ka pahu alkali, hoʻoheheʻe ʻia ka soda i loko o ka wai wela ma kahi mahana o 50-60 ° C, a laila urea
Hoʻohui ʻia e hoʻoheheʻe i 21 ° Be solution. A laila i loko o ka ipu hoʻēmi hoʻoliʻiliʻi, lohi ma o ka bromine, kaohi i ka mahana o ke ʻano o 75-85 ° C, i ka pH o 6-7, ʻo ia hoʻi, e hiki i ka hopena o ka hopena. e hoʻokū i ka bromine a me ka hoʻoulu ʻana, e loaʻa i ka hopena sodium bromide.
Hoʻololi i ka PH i ka 2 me ka waikawa hydrobromic, a laila hoʻoponopono i ka pH i ka 6-7 me ka urea a me ka sodium hydroxide e hemo ai ka bromate. Hoʻomehana ʻia ka hopena i kahi paila a hoʻohui ʻia kahi hopena momona o barium bromide ma pH6 - 7 e wehe i ka sulfate Inā nui ka paʻakai barium, hiki ke hoʻohui ʻia ka waikawa sulfuric e kāpae. Hoʻohui i ke kalapona hana ʻia ma hope o ka hemo ʻana i nā haumia, a kau iā ia no 4-6 mau hola. Ma hope o ka wehewehe ʻana o ka hopena, ua kānana ʻia, hoʻomohu ʻia ma ke kaomi lewa, a hoʻopiha ʻia nā mea waena i nā manawa he nui. E hōʻoki i ka hānai ʻana no 2 mau hola ma mua o ka crystallization. Hoʻololi i ka pH i ka 6-7 1 hola ma mua o ka crystallization. Hoʻokaʻawale ʻia ka sodium bromide a hoʻomaloʻo ʻia i kahi mea holoi pahu hoʻokaʻa.
Kumuhana o ka hopena: 3Br2 + 3Na2CO3 + NH2ConH2 = 6NaBr + 4CO2 ↑ + N2 ↑ + 2H2O
