1. Cov yam ntxwv thiab cov txheej txheem purification ntawm anhydrous tooj liab sulfate:
Lub cev pom lub cev yog cov hmoov dawb lossis tawv dawb, soluble hauv dej thiab dilute ethanol, tab sis insoluble nyob rau hauv abcute aganol. Nws muaj qhov ruaj khov thiab tshuaj ruaj khov ruaj khov, tsis yooj yim rau decompose, thiab nyuaj rau kev hnov mob nrog lwm cov teb chaws. Zoo thermal stability, yooj yim rau delibicesce nyob rau hauv huab cua noo, sib sau dub tooj liab oxide thaum kub. Thaum yaj hauv dej, anhydrous tooj liab sulfate nrog cov dej moleculate los ua kom sulple tooj liab sulfate (Cuso4 oo tau siv nyob rau hauv kev kuaj muaju qhia thiab tshuaj lom neeg. Nws tuaj yeem cuam tshuam nrog ntau cov organic sib xyaw, xws li reacting nrog roj fatty los tsim cov alkylate coj. Anhydrous tooj liab sulfate muaj qee yam ntawm toxicity. Thaum siv nws, koj yuav tsum ua raws li cov cai thiab kev ua haujlwm kom ua kom muaj kev nyab xeeb.
1. Cov txheej txheem lim dej ntawm anhydrous tooj liab sulfate feem ntau adopts cov kauj ruam hauv qab no:
Kev tshem tawm ntawm cov khoom siv raw: muab cov tooj liab nyoos sulfate rau hauv lub taub hau tank, thiab cua sov kom ntev li 60 ~ 80 ° C kom yaj tag nws. Oxidation thiab imprivity tshem tawm: Ntxiv ib tus nqi oxidants tsim nyog, xws li nitrical peroxide, thiab lwm yam kom oxidize lub impurities hauv kev daws. Pom: lim cov tshuaj oxidized kom tshem tawm cov khoom impurities. Kho tus nqi pH: Ntxiv qhov tsim nyog ntawm alkali, xws li socium hydroxide, thiab lwm yam. Nag los: Precipition cov tshuaj kom ua tiav nag lossis daus hydroxide. Ntxuav: ntxuav cov tooj liab nag los hydroxide kom tshem tawm cov kab txawv. Kom qhuav: Qhuav ntxuav cov tooj liab hydroxide kom tshem tawm cov dej noo. Hlawv: Cov tooj liab qhuav hydroxide yog hlawv kom decompain nws rau hauv tooj liab sulfate. Cua txias: cub hlawv sulfate yog txias kom tau txais anhydous tooj liab sulfate khoom.
2. CatealyS rau cov hluavtaws ntawm cov txuj lom thiab cov lus nug hauv kev lag luam organic, thiab siv ua cov av polymerization ntawm cesol methacrylate. Nyob rau hauv cov txheej txheej kev lag luam, anhydrous tooj liab sulfate yog siv los ua biocide nyob rau hauv kev tsim cov nkoj hauv qab cov xim tiv thaiv kab hauv qab. Nyob rau hauv cov nqe lus ntawm cov analytical reagents, anhydrous tooj liab sulfate tuaj yeem siv los npaj cov tshuaj yej featagent rau kev txheeb xyuas cov piam thaj rau kev txheeb xyuas cov piam thaj rau kev txheeb xyuas cov piam thaj kom txheeb xyuas cov protein. Anhydrous tooj liab sulfate kuj tau siv los ua cov zaub mov-theem chelating tus neeg sawv cev thiab hais kom meej hauv cov txheej txheem qe thiab caw cov txheej txheem sib xyaw. Hauv kev ua liaj ua teb
2. Nrhiav tau thiab kev tsim khoom ntawm cov qib tooj liab sulfate:
Tsuas yog tsom rau nws cov kev coj dawb huv, cov ntsiab lus xyaw thiab cov ntsiab lus hlau hnyav. Cov nam ntau lawm suav nrog cov ntxhia ua tiav, ua kom leaching, extraction, electroly thiab lwm cov kauj ruam.
Rau kev sim, lub hom phiaj tseem ceeb yog kev sim ntau yam ntsuas tooj liab, xws li tooj liab, cov ntsiab lus av, thiab lwm yam ntawm cov ntsuas no tuaj yeem paub tias qhov zoo Ntawm pub qib tooj liab sulfate nce mus txog tus qauv thiab ua raws li cov qauv hauv tebchaws.
Nyob rau hauv cov nqe lus ntawm kev tsim khoom, nws yog thawj zaug tsim nyog los ua dua tshiab thiab xaiv cov tooj liab sulfate.then cov ntaub ntawv raw yog ua tiav los ntawm cov ntxhia ua
Kev ua ntej yog nqa tawm kom tau txais ore nrog cov ntsiab lus tooj liab ntau dua. Tus tooj liab yog tom qab ntawd rho tawm los ntawm ore los ntawm cov qauv tshuaj xws li leaching thiab extraction. Thaum kawg, rho tawm cov tooj Ions yog txo kom nws yog xim tooj liab los ntawm kev siv electrolysis thiab txuas ntxiv mus rau hauv cov qib noj liab sulfate.
