Thepa ea 'Mele
1) Thepa: kristale ea cubic e se nang mebala kapa phofo e tšoeu ea granular. Ha e na monko, e letsoai ebile e baba hanyane.
2) Boima ba 'mele (g/mL, 25 ° C) : 3.203;
3) Sebaka se qhibilihang (℃) : 755;
4) Sebaka se belang (° C, khatello ea sepakapaka): 1390;
5) Index ea Refractive: 1.6412;
6) Ntlha ea Flash (° C) : 1390
7) Solubility: ho bonolo ho qhibiliha ka metsing (solubility ke 90.5g / 100ml metsi ka 20 ° C, solubility ke 121g / 100ml metsi ka 100 ° C), tharollo ea metsi ha e nke lehlakore ebile e tsamaisa.Hanyenyane e qhibiliha ka joala, e qhibiliha ka acetonitrile, acetonitrile.
8) Khatello ea mouoane (806 ° C): 1mmHg.
Lintho tsa lik'hemik'hale
1) Anhydrous sodium bromide crystals precipitate ka sodium bromide solution at 51 ℃, and dihydrate e thehoa ha mocheso o le tlase ho 51℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Bromide ea sodium e ka nkeloa sebaka ke khase ea chlorine ho fana ka bromine.
2Br-+Cl2=Br2+2Cl-
3) Sodium bromide e sebetsana le concentrated sulfuric acid ho hlahisa bromine, ke hore, tlas'a ketso ea acid e matla ea oxidizing, bromide ea sodium e ka ba oxidized 'me ea lokolohile ho bromine.
2NaBr+3H2SO4 (e tsepamisitsoe maikutlo) =2NaHSO4+Br2+SO2↑+2H2O
4) Sodium bromide e ka sebetsana le dilute sulfuric acid ho hlahisa hydrogen bromide.
NaBr+H2SO4=HBr+NaHSO4
5) Ka har'a tharollo e nang le metsi, sodium bromide e ka sebetsana le li-ion tsa silevera ho etsa bromide ea silevera e bosehla bo bobebe.
Br – + Ag + = AgBr ka ho le letšehali
6) Electrolysis ea sodium bromide boemong bo qhibilihisitsoeng ho hlahisa khase ea bromine le tšepe ea sodium.
2 nabr e matlafalitsoeng = 2 le + Br2
7) Tharollo ea metsi a sodium bromide e ka hlahisa bromate ea sodium le hydrogen ka electrolysis.
NaBr + 3H2O= electrolytic NaBrO3 + 3H2↑
8) Karabelo ea 'mele e ka etsahala, joalo ka karabelo e kholo ea ho etsa bromoethane:
NaBr + – H2SO4 + CH2CH2OH ⇌ NaHSO4 + CH3CH2Br + H2O

Mekhoa ea ho Lokisetsa

1) Mokhoa oa indasteri
Bromine e feteletseng hanyane e eketsoa ka kotloloho ho tharollo e futhumetseng ea sodium hydroxide ho hlahisa motsoako oa bromide le bromate:
3Br2+6NaOH=5NaBr+NaBrO3+3H2O
Motsoako o fetoha mouoane hore o ome, 'me masala a tiileng a hlahisoang a kopantsoe le toner ebe a futhumatsoa ho fokotsa bromate ho bromide:
NaBrO3 = NaBr + 3 c + 3 co ngola
Qetellong, e qhibiliha ka metsing, ebe e sefshoa le ho khantša, ebe e omisoa ka likhato tse 110 ho isa ho tse 130 tsa Celsius.
*Mokhoa ona ke mokhoa o akaretsang oa ho lokisa bromide ka bromine mme hangata o sebelisoa indastering.
2) Mokhoa oa ho se nke lehlakore
Sebelisa sodium bicarbonate e le lintho tse bonahalang tse tala: qhala sodium bicarbonate ka metsing, 'me joale neutralize ka 35% -40% hydrobromide ho fumana sodium bromide tharollo, e leng condensed le cooled ho precipitate sodium bromide dihydrate.Filter, qhala dihydrate ka palo e nyenyane ea metsi, le tlohele bromine metsi ho fihlela 'mala oa bromine feela hlaha ka an hydrogen aquelour solution. pheha.Ka mocheso o phahameng, anhydrous crystallization precipitates, 'me ka mor'a ho omisa, e fetisetsoa ho se omisang' me e bolokoe ho 110 bakeng sa hora ea 1. E ntan'o pholile ka se omisitsoeng ka calcium bromide desiccant ho fumana anhydrous sodium bromide (reagent grade).
Molao-motheo oa ho itšoara: HBr+ NAHCO ₃→NaBr+CO2↑+H2O
Ka 40% ea alkali ea metsi e le lintho tse tala: beha hydrobromide acid ka pitseng ea karabelo, tlas'a ho tsosoa kamehla, butle-butle eketsa 40% ea tharollo ea alkali ea metsi, e fokotsa ho pH7.5 - 8.0, e arabela ho hlahisa sodium bromide solution.The sodium bromide solution e ne e le centrifuged le e tlhotliloeng ka har'a tanka ea ho boloka tharollo ea sodium bromide. 1. 55° E be kapa joalo, centrifugal filtration, filtration into concentrated sodium bromide liquid storage tank.Ebe e hatelloa ka har'a tanka ea crystallization, ka har'a kristalllization e pholisang e susumetsang, 'me joale crystallization ea karohano ea centrifugal, sehlahisoa se felileng.Joala bo tsoetsoeng bo khutlisetsoa tanka ea ho boloka metsi a sodium bromide.
Molao-motheo oa ho itšoara: HBr+NaOH→NaBr+H2O
3) Mokhoa oa ho fokotsa urea:
Ka tanka ea alkali, soda e qhibiliha ka metsing a chesang ka mocheso oa 50-60 ° C, ebe joale urea.
e eketsoa ho qhibiliha 21 ° E-ba tharollo. Joale ka pitseng ea phokotso ea karabelo, butle-butle ka bromine, laola mocheso oa karabelo oa 75-85 ° C, ho pH ea 6-7, ke hore, ho fihla qetellong ea karabelo, emisa bromine le ho hlohlelletsa, fumana tharollo ea sodium bromide.
Fetola pH ho 2 ka hydrobromic acid, ebe u fetola pH ho 6-7 ka urea le sodium hydroxide ho tlosa bromate. Tharollo e futhumatsoa ho pheha 'me tharollo e tletseng ea barium bromide e eketsoa ka pH6 - 7 ho tlosa sulfate.Haeba letsoai la barium le le ngata haholo, hlapolla sulfuric acid e ka ekeletsoa ho tlosa carbon dioxide, ka mor'a hore ho sebelisoe lintho tse 6 ka mor'a hore ho be le carbon activated. lihora. Ka mor'a hore tharollo e hlakisoe, e sefshoa, e ntšoa mouoane tlas'a khatello ea sepakapaka, 'me thepa e bohareng e tlatsoa ka makhetlo a mangata. Emisa ho fepa lihora tsa 2 pele ho crystallization. Lokisa pH ho 6-7 1 hora pele ho crystallization.Sodium bromide e ne e arohane 'me e omisitsoe ka mochine o omisang drum oa rotary.
Molao-motheo oa karabelo: 3Br2+3Na2CO3+ NH2ConH2 =6NaBr+4CO2↑+N2↑+2H2O
