Cov khoom siv tshuaj
Potassium bromide yog ib tug raug ionic compound uas yog kiag li ionized thiab nruab nrab tom qab tau yaj nyob rau hauv dej. Feem ntau siv los muab bromide ions - Silver bromide rau kev yees duab siv tau los ntawm cov nram qab no cov tshuaj tiv thaiv tseem ceeb:
KBr(aq) + AgNO3(aq) → AgBr(s) + KNO3(aq)
Cov bromide ion Br- hauv cov kua dej tuaj yeem tsim cov complexes nrog qee cov hlau halides, xws li:
KBr(aq) + CuBr2(aq) → K2[CuBr4](aq)

1) ElectrolysisTxoj kev
Yuav los ntawm poov tshuaj bromide thiab poov tshuaj hydroxide synthesis nrog dej distilled yaj mus rau hauv cov electrolyte, thawj batch ntawm crude khoom, electrolytic tom qab 24 teev tom qab txhua 12 teev siv ntxhib, cov khoom ntxhib yog ntxuav nrog distillation hydrolysis tom qab tshem tawm KBR, ntxiv ib qho me me ntawm cov poov tshuaj hydroxide kho pH lim tom qab 8. lub crystallizer thiab nruab nrab-txias rau chav tsev kub, crystallization, sib cais, ziab, poov tshuaj bromate yog tsim los ntawm cov khoom.
2) Chlorine oxidationMethod
Tom qab cov tshuaj tiv thaiv ntawm txiv qaub mis thiab bromide, chlorine roj tau ntxiv rau chlorine oxidation cov tshuaj tiv thaiv, thiab cov tshuaj tiv thaiv tau xaus thaum pH tus nqi mus txog 6 ~ 7.Tom qab tshem tawm slag, cov filtrate yog evaporated.Barium chloride tov yog ntxiv rau react los tsim barium bromate nag lossis daus, thiab cov dej lim dej ntxiv rau cov dej nag thiab cov carbonate ntxiv rau cov dej nag thiab dej. decomposition tshuaj. Crude potassium bromate yog ntxuav nrog me me ntawm cov dej distilled rau ob peb zaug, ces lim, evaporated, txias, crystallized, sib cais, qhuav thiab crushed los npaj cov khoom noj khoom haus poov tshuaj bromate.
3) Bromo-PotassiumHydroxideMethod
Nrog rau kev lag luam bromine thiab poov tshuaj hydroxide ua raw cov ntaub ntawv, poov tshuaj hydroxide tau yaj mus rau hauv kev daws nrog 1.4 npaug ntawm cov dej, thiab bromine tau ntxiv nyob rau hauv tas li stirring.Thaum bromide ntxiv rau ib tug npaum li cas, dawb crystals yog precipitated tawm kom tau poov tshuaj bromate crude.
Txuas ntxiv ntxiv bromine kom txog thaum cov kua liab liab.Tib lub sijhawm ntxiv bromine, dej txias tas li ntxiv rau kev daws kom tsis txhob poob ntawm bromine volatilization vim qhov kub thiab txias.Recrystallized dua, lim, qhuav, ces yaj nrog dej deionized, thiab ntxiv ib qho me me ntawm cov poov tshuaj hydroxide kom tshem tawm cov bromine ntau dhau thaum lub sij hawm ua tiav cov khoom siv, cov khoom siv rov ua kom tiav, rov ua dua tshiab.
1) Photosensitive cov ntaub ntawv kev lag luam siv nyob rau hauv lub tsim ntawm photosensitive zaj duab xis, tsim tawm, tsis zoo thickening tus neeg saib xyuas, toner thiab xim duab bleaching tus neeg saib xyuas;
2) Siv los ua cov paj hlwb tranquilizer hauv tshuaj (peb ntsiav tshuaj bromine);
3) Siv rau kev tshuaj xyuas tshuaj reagents, spectroscopic thiab infrared kis tau tus mob, ua xab npum tshwj xeeb, nrog rau engraving, lithography thiab lwm yam;
4) Nws kuj tseem siv los ua cov tshuaj ntsuam xyuas reagent.
