Cov ntsiab lus ntawm cov khoom

Cov Txheej Txheem Npaj

1) Txoj kev lag luam
Cov bromine ntau dhau me ntsis yog ntxiv ncaj qha rau cov kua sodium hydroxide thermal kom tsim tau cov bromide thiab bromate sib xyaw:
3Br2 + 6NaOH = 5NaBr + NaBrO3 + 3H2O
Cov khoom sib tov no tau ua kom qhuav, thiab cov khoom seem uas tau los ntawm kev sib tov nrog toner thiab cua sov kom txo cov bromate rau bromide:
NaBrO3 = NaBr + 3c + 3co sau
Thaum kawg, nws tau yaj rau hauv dej, tom qab ntawd lim thiab crystallized, thiab ziab ntawm 110 txog 130 degrees Celsius.
* Txoj kev no yog txoj kev dav dav ntawm kev npaj bromide los ntawm bromine thiab feem ntau yog siv hauv kev lag luam.
2) Txoj kev ua kom tsis muaj zog
Siv sodium bicarbonate ua cov khoom siv raw: yaj sodium bicarbonate hauv dej, thiab tom qab ntawd neutralize nws nrog 35% -40% hydrobromide kom tau txais sodium bromide kua, uas yog condensed thiab txias kom precipitate sodium bromide dihydrate. Lim, yaj dihydrate nrog me ntsis dej, nchuav bromine dej kom txog thaum xim ntawm bromine tshwm sim. Ua kom sov, decolor hauv cov kua dej ntawm hydrogen sulfide, thiab coj mus rau ib lub rhaub. Thaum kub siab, anhydrous crystallization precipitates, thiab tom qab ziab, nws raug xa mus rau lub tshuab ziab thiab khaws cia ntawm 110 rau 1 teev. Tom qab ntawd nws raug txias hauv lub tshuab ziab nrog calcium bromide desiccant kom tau txais anhydrous sodium bromide (reagent qib).
Txoj Cai ntawm Cov Tshuaj: HBr+ NAHCO₃→NaBr+CO2↑+H2O
Nrog 40% kua alkali ua raw khoom: muab hydrobromide acid rau hauv lub lauj kaub tshuaj tiv thaiv, nyob rau hauv qhov sib xyaw tas li, maj mam ntxiv 40% kua alkali kua, neutralize rau pH7.5 - 8.0, teb kom tsim cov sodium bromide kua. Cov sodium bromide kua tau centrifuged thiab lim rau hauv lub tank cia kua sodium bromide. Tom qab ntawd mus rau hauv lub tank evaporation concentration, nruab nrab pub 1-2 zaug, mus rau qhov hnyav tshwj xeeb ntawm 1. 55 ° Ua lossis li ntawd, centrifugal filtration, lim rau hauv lub tank cia kua sodium bromide concentrated. Tom qab ntawd nias rau hauv lub tank crystallization, hauv qhov sib xyaw txias crystallization, thiab tom qab ntawd crystallization ntawm centrifugal sib cais, cov khoom tiav. Cov cawv niam rov qab mus rau lub tank cia kua sodium bromide dilute.
Txoj cai ntawm cov tshuaj tiv thaiv: HBr + NaOH → NaBr + H2O
3) Txoj kev txo Urea:
Hauv lub tank alkali, cov dej qab zib raug yaj rau hauv dej kub ntawm qhov kub ntawm 50-60 ° C, thiab tom qab ntawd urea.
ntxiv rau kom yaj 21°Be kua. Tom qab ntawd mus rau hauv lub lauj kaub txo qis, maj mam dhau los ntawm bromine, tswj qhov kub ntawm cov tshuaj tiv thaiv ntawm 75-85 ° C, mus rau pH ntawm 6-7, uas yog, kom mus txog qhov kawg ntawm cov tshuaj tiv thaiv, nres bromine thiab do, tau txais sodium bromide kua.
Kho pH rau 2 nrog hydrobromic acid, thiab tom qab ntawd kho pH rau 6-7 nrog urea thiab sodium hydroxide kom tshem tawm bromate. Cov tshuaj raug cua sov kom npau thiab ntxiv cov tshuaj barium bromide saturated ntawm pH6 - 7 kom tshem tawm cov sulfate. Yog tias barium ntsev ntau dhau, dilute sulfuric acid tuaj yeem ntxiv kom tshem tawm. Ntxiv cov pa roj carbon activated rau cov khoom siv tshuaj tom qab tshem tawm cov khoom tsis huv, thiab muab tso rau 4-6 teev. Tom qab cov tshuaj tau ua kom meej, nws raug lim, evaporated ntawm atmospheric siab, thiab cov khoom nruab nrab raug sau ntau zaus. Tsum pub rau 2 teev ua ntej crystallization. Kho pH rau 6-7 1 teev ua ntej crystallization. Cov sodium bromide tau sib cais thiab ziab hauv lub tshuab ziab khaub ncaws rotary.
Lub hauv paus ntsiab lus ntawm kev ua tshuaj: 3Br2 + 3Na2CO3 + NH2ConH2 = 6NaBr + 4CO2↑ + N2↑ + 2H2O
