Hunhu hwemuviri uye hwemakemikari
Zvimiro zvemuviri
1) Hunhu: Hupfu hwe cubic crystal kana chena granular husina ruvara. Hahunhuhwi, hune munyu uye hunovava zvishoma.
2) Kuwanda kwemvura (g/mL, 25 ° C): 3.203;
3) Nzvimbo yekunyunguduka (℃): 755;
4) Pokufashaira (° C, kumanikidzwa kwemhepo): 1390;
5) Chiratidzo cheRefractive: 1.6412;
6) Poindi yekupenya (° C): 1390
7) Kunyungudika: inonyungudika nyore nyore mumvura (kunyungudika i90.5g/100ml yemvura pa20 ° C, kunyungudika i121g/100ml yemvura pa100 ° C), mvura inonyungudika haina kwayakarerekera uye inofambisa mvura. Inonyungudika zvishoma mualcohol, inonyungudika muacetonitrile, acetic acid.
8) Kumanikidzwa kwemhepo (806 ° C): 1mmHg.
Hunhu hwemakemikari
1) Anhydrous sodium bromide crystals inowira mumushonga we sodium bromide pa51℃, uye dihydrate inoumbwa kana tembiricha iri pasi pe51℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Sodium bromide inogona kutsiviwa negesi rechlorine kuti ipe bromine.
2Br-+Cl2=Br2+2Cl-
3) Sodium bromide inosangana nesulfuric acid yakakora kuti igadzire bromine, kureva kuti, pasi pesimba re oxidizing acid, sodium bromide inogona kuoxidized uye isina bromine.
2NaBr+3H2SO4 (yakakomberedzwa) =2NaHSO4+Br2+SO2↑+2H2O
4) Sodium bromide inogona kuita mubatanidzwa ne sulfuric acid yakasanganiswa kuti igadzire hydrogen bromide.
NaBr+H2SO4=HBr+NaHSO4
5) Mumvura ine mvura, sodium bromide inogona kusangana nemaion esirivha kuita bromide yesirivha yakasimba yero.
Br – + Ag + = AgBr kuruboshwe
6) Kugadziriswa kwemagetsi e sodium bromide muchimiro chekunyunguduka kuti kugadzirwe gasi re bromine nesimbi ye sodium.
2 nabr ine simba = 2 na + Br2
7) Sodium bromide aqueous solution inogona kugadzira sodium bromate nehydrogen kuburikidza ne electrolysis.
NaBr + 3H2O= NaBrO3 yemagetsi + 3H2↑
8) Maitiro ezvisikwa anogona kuitika, akadai sekuita kukuru kwekugadzira bromoethane:
NaBr + – H2SO4 + CH2CH2OH ⇌ NaHSO4 + CH3CH2Br + H2O
Ruzivo rwechigadzirwa
Nzira dzekugadzirira
1) Nzira yeindasitiri
Bromine yakawandisa zvishoma inowedzerwa zvakananga kune saturated sodium hydroxide thermal solution kuti igadzire musanganiswa webromide nebromate:
3Br2+6NaOH=5NaBr+NaBrO3+3H2O
Musanganiswa wacho unopiswa kuti uome, uye zvasara zvakasimba zvinobva zvasanganiswa netoner zvodziiswa kuti bromate iite bromide:
NaBrO3 = NaBr + 3 c + 3 co nyora
Pakupedzisira, inonyungudutswa mumvura, yozosefa yoita crystallized, yoomeswa pa 110 kusvika 130 degrees Celsius.
*Iyi nzira ndiyo nzira yakajairika yekugadzira bromide nebromine uye inowanzo shandiswa mumaindasitiri.
2) Nzira yekubvisa tsvina
Shandisa sodium bicarbonate sezvinhu zvakabikwa: nyungudutsa sodium bicarbonate mumvura, wobva waibvisa ne35%-40% hydrobromide kuti uwane sodium bromide solution, iyo inosanganiswa uye inotonhorerwa kuti iite sodium bromide dihydrate. Sefa, nyungudutsa dihydrate nemvura shoma, donhedza mvura yebromine kusvika ruvara rwebromine rwaonekwa. Pisa, bvisa ruvara mumvura ine hydrogen sulfide, woiisa pamoto. Pakupisa kwakanyanya, anhydrous crystallization inowira, uye mushure mekuoma, inoendeswa kudryer uye inochengetwa pa110 kweawa imwe. Inobva yatonhodzwa mudryer ine calcium bromide desiccant kuti iwane anhydrous sodium bromide (reagent grade).
Nheyo yemhinduro: HBr+ NAHCO ₃→NaBr+CO2↑+H2O
Ne 40% yealkali yemvura sezvinhu zvakabikwa: isa hydrobromide acid muhari yereaction, uchikurunga nguva dzose, wedzera zvishoma nezvishoma 40% yealkali yemvura, gadzirisa kusvika pH7.5 - 8.0, gadzirisa kuti ugadzire sodium bromide solution. Sodium bromide solution yakatenderedzwa mukati me centrifuge ndokuseferwa mu dilute sodium bromide solution storage tank. Zvadaro mu evaporation tank concentration, pakati pekudya 1-2, kusvika pahukuru hwe 1.55°Be kana so, centrifugal filtration, filtration mu concentrated sodium bromide liquid storage tank. Zvadaro yakamanikidzwa mu crystallization tank, mu stirling cooling crystallization, uye ipapo crystallization yekuparadzaniswa kwe centrifugal, chigadzirwa chapera. Mother liquor inodzoserwa mu dilute sodium bromide liquid storage tank.
Nheyo yemhinduro: HBr+NaOH→NaBr+H2O
3) Nzira yekuderedza urea:
Mutangi realkali, soda inonyungudutswa mumvura inopisa patembiricha ye50-60 °C, uye wozobva waisa urea.
Inowedzerwa kuti inyungudise 21°Be solution. Zvadaro muhari yekuderedza reaction, zvishoma nezvishoma kuburikidza nebromine, dzora tembiricha ye reaction ye75-85 °C, kusvika kupH ye6-7, kureva kuti, kusvika kumagumo e reaction, misa bromine wokurunga, tora sodium bromide solution.
Gadzirisa pH kusvika pa2 uchishandisa hydrobromic acid, wobva wagadzirisa pH kusvika pa6-7 uchishandisa urea uye sodium hydroxide kubvisa bromate. Mhinduro yacho inopiswa kusvika yafashaira uye mhinduro yakazara ye barium bromide inowedzerwa pa pH6 — 7 kubvisa sulfate. Kana munyu we barium wakawandisa, sulfuric acid yakasanganiswa inogona kuwedzerwa kubvisa. Wedzera activated carbon kune reaction material mushure mekubvisa tsvina, woiisa kwemaawa 4-6. Mushure mekunge mhinduro yajekeswa, inosefetwa, yopiswa nekumanikidzwa kwemhepo, uye zvinhu zvepakati zvinozadzwa kakawanda. Mira kupa chikafu kwemaawa maviri usati waita crystallization. Gadzirisa pH kusvika pa 6-7 awa imwe usati waita crystallization. Sodium bromide yakaparadzaniswa yoomeswa murotary drum dryer.
Nheyo yekuita: 3Br2+3Na2CO3+ NH2ConH2 =6NaBr+4CO2↑+N2↑+2H2O
