8) Vapor siab (806 ° C): 1mmHg.
Cov khoom siv tshuaj
1) Anhydrous sodium bromide crystals precipitate hauv cov tshuaj sodium bromide ntawm 51 ℃, thiab dihydrate yog tsim thaum kub qis dua 51 ℃.
NaBr + 2 h2o = NaBr · 2 H2O
2) Sodium bromide tuaj yeem hloov tau los ntawm cov roj chlorine los muab bromine.
2Br-+Cl2=Br2+2Cl-
3) Sodium bromide reacts nrog concentrated sulfuric acid los tsim bromine, uas yog, nyob rau hauv qhov kev txiav txim ntawm muaj zog oxidizing acid, sodium bromide yuav oxidized thiab dawb los ntawm bromine.
2NaBr + 3H2SO4 (concentrated) = 2NaHSO4 + Br2 + SO2↑ + 2H2O
4) Sodium bromide tuaj yeem cuam tshuam nrog dilute sulfuric acid los tsim hydrogen bromide.
NaBr+H2SO4=HBr+NaHSO4
5) Hauv cov tshuaj aqueous, sodium bromide tuaj yeem hnov ​​​​mob nrog nyiaj ions los ua lub teeb daj daj nyiaj bromide.
Br – + Ag + = AgBr laug
6) Electrolysis ntawm sodium bromide hauv lub xeev molten los tsim cov roj bromine thiab sodium hlau.
2 energized nabr = 2 na + Br2
7) Sodium bromide aqueous tov tuaj yeem tsim sodium bromate thiab hydrogen los ntawm electrolysis.
NaBr + 3H2O = electrolytic NaBrO3 + 3H2↑
8) Cov tshuaj tiv thaiv kab mob tuaj yeem tshwm sim, xws li cov tshuaj tiv thaiv tseem ceeb los ua bromoethane:
NaBr + – H2SO4 + CH2CH2OH ⇌ NaHSO4 + CH3CH2Br + H2O

Txoj Kev Npaj

1) Muaj txoj hauv kev
Cov bromine ntau dhau me ntsis yog ncaj qha ntxiv rau saturated sodium hydroxide thermal tov los tsim kom muaj kev sib xyaw ntawm bromide thiab bromate:
3Br2+6NaOH = 5NaBr+NaBrO3+3H2O
Cov sib tov yog evaporated kom qhuav, thiab cov khoom seem seem yog tov nrog toner thiab rhuab kom txo tau cov bromate rau bromide:
NaBrO3 = NaBr + 3 c + 3 co write
Thaum kawg, nws yog yaj nyob rau hauv dej, ces lim thiab crystallized, thiab qhuav ntawm 110 mus rau 130 degrees Celsius.
* Txoj kev no yog txoj kev dav dav ntawm kev npaj bromide los ntawm bromine thiab feem ntau siv hauv kev lag luam.
2) Neutralization txoj kev
Siv sodium bicarbonate raws li raw khoom: yaj sodium bicarbonate hauv dej, thiab tom qab ntawd neutralize nws nrog 35% -40% hydrobromide kom tau sodium bromide tov, uas yog condensed thiab txias rau precipitate sodium bromide dihydrate.Filter, dissolve lub dihydrate nrog ib tug me me ntawm dej, tee bromine dej kom txog rau thaum ib tug xim ntawm bromine sulfide ntawm hydrochloric acid, nws tshwm sim nyob rau hauv ib tug hydrochloric acid. Thaum kub kub, anhydrous crystallization precipitates, thiab tom qab ziab, nws raug xa mus rau lub tshuab ziab khaub ncaws thiab khaws cia rau ntawm 110 rau 1 teev.
Reaction txoj cai: HBr + NAHCO ₃ → NaBr + CO2↑ + H2O
Nrog 40% kua alkali raws li raw khoom: muab hydrobromide acid rau hauv cov tshuaj tiv thaiv lauj kaub, nyob rau hauv tas li stirring, maj mam ntxiv 40% kua alkali tov, neutralize rau pH7.5 - 8.0, react los tsim sodium bromide tov.Cov sodium bromide tov yog centrifuged thiab lim rau hauv dilute sodium bromide tov tank evaporation tov khoom. 1-2 zaug, mus rau qhov tshwj xeeb lub ntiajteb txawj nqus ntawm 1. 55 ° Be los yog li ntawd, centrifugal pom, pom mus rau hauv concentrated sodium bromide kua cia tank.Tom qab ntawd nias rau hauv lub tank crystallization, nyob rau hauv lub stirring txias crystallization, thiab ces lub crystallization ntawm centrifugal sib cais, cov khoom tiav lawm.Cov kua dej qab zib yog xa rov qab mus rau sodium bromide tank.
Reaction txoj cai: HBr + NaOH → NaBr + H2O
3) Urea txo txoj kev:
Hauv lub tank alkali, cov dej qab zib yog yaj hauv dej kub ntawm qhov kub ntawm 50-60 ° C, thiab tom qab ntawd urea.
yog ntxiv rau yaj 21 ° Be tov.Tom qab ntawd rau hauv qhov txo cov tshuaj tiv thaiv lub lauj kaub, maj mam los ntawm bromine, tswj cov tshuaj tiv thaiv kub ntawm 75-85 ° C, mus rau pH ntawm 6-7, uas yog, kom ncav cuag qhov kawg ntawm cov tshuaj tiv thaiv, nres bromine thiab nplawm, tau sodium bromide tov.
Kho pH mus rau 2 nrog hydrobromic acid, thiab tom qab ntawd kho pH mus rau 6-7 nrog urea thiab sodium hydroxide kom tshem tawm bromate.Cov tshuaj yog rhaub rau boil thiab ib tug saturated tov ntawm barium bromide yog ntxiv ntawm pH6 - 7 kom tshem tawm cov sulfate.Yog hais tias barium ntsev ntau dhau, dilute sulfuric acid yuav tsum tau ntxiv rau cov tshuaj tiv thaiv tom qab tshem tawm. rau 4-6 teev. Tom qab qhov kev daws teeb meem tau pom meej, nws tau lim, evaporated ntawm atmospheric siab, thiab cov khoom nruab nrab tau ntim ob peb zaug. Tsis txhob pub mis rau 2 teev ua ntej crystallization.Kho pH rau 6-7 1 teev ua ntej crystallization.Cov sodium bromide tau muab cais thiab ziab hauv lub tshuab ziab khaub ncaws.
Lub hauv paus ntsiab lus ntawm cov tshuaj tiv thaiv: 3Br2 + 3Na2CO3 + NH2ConH2 = 6NaBr + 4CO2↑ + N2↑ + 2H2O
