Calcium lignosulfonat yog lub ntuj organic acid ntsev compound muab los ntawm lignin. Nws muaj qhov zoo thermal stability thiab dej solubility, thiab yog dav siv nyob rau hauv kev tsim kho cov ntaub ntawv, tshuaj lom neeg kev lag luam thiab lwm yam teb.

Cov ntaub ntawv raw ntawm LSACa feem ntau yog los ntawm cov nroj tsuag ntuj biomass xws li cellulose thiab lignocellulose. Cov ntaub ntawv nyoos no yog nplua nuj nyob hauv lignin thiab yog qhov tseem ceeb ntawm LSACa. Hauv cov txheej txheem tsim khoom tiag tiag, cov khoom sib txawv ntawm lignin raw cov ntaub ntawv tuaj yeem raug xaiv rau kev sib xyaw, xws li ntoo tawv, softwood, sawdust, thiab lwm yam. Cov ntaub ntawv nyoos no muaj qee qhov sib txawv ntawm lignin cov ntsiab lus thiab cov yam ntxwv ntawm cov qauv, uas muaj qee yam cuam tshuam rau cov txheej txheem synthesis. Tsis tas li ntawd, nws tseem yuav tsum tau xaiv cov kua qaub uas tsim nyog thiab cov tshuaj reactants. Cov kua qaub reactants feem ntau yog siv rau kev sib cais thiab kev ua kom huv ntawm lignin, thaum cov tshuaj reactants yog siv rau kev sib txuas ntawm LSACa.

Cov tshuaj synthesis ntawm LSACa feem ntau suav nrog cov kauj ruam xws li kev sib cais lignin, sulfation, thiab calcium ntsev pauv. Thaum cov txheej txheem tshuaj tiv thaiv, cov tshuaj tiv thaiv kub, pH tus nqi, thiab lub sijhawm tshuaj tiv thaiv yuav tsum tau tswj. Rau cov ntaub ntawv sib txawv thiab cov tshuaj tiv thaiv, cov kev tswj xyuas ntawm cov tshuaj tiv thaiv kuj yuav txawv. Feem ntau hais lus, thaum lub sij hawm sib cais ntawm lignin, nws yog ib qho tsim nyog yuav tsum tau ntxiv cov kua qaub kua qaub rau kev sib cais, thiab tom qab ntawd cais los ntawm Fehling cov tshuaj tiv thaiv, tooj liab nitrate reagent thiab lwm txoj kev. Nyob rau hauv cov tshuaj tiv thaiv sulfation, nws yog ib qho tsim nyog yuav tsum tau ntxiv qhov tsim nyog ntawm cov concentrated sulfuric acid raws li catalyst, thiab tswj cov tshuaj tiv thaiv kub ntawm 60-80 ° C., thiab lub sij hawm cov tshuaj tiv thaiv yog 1-2 teev. Nyob rau hauv cov tshuaj calcium ntsev pauv cov tshuaj tiv thaiv, ib qho tsim nyog ntawm calcium ntsev tov yuav tsum tau ntxiv rau cov tshuaj tiv thaiv, cov tshuaj tiv thaiv kub yog tswj ntawm 50-60 degree, thiab cov tshuaj tiv thaiv lub sij hawm yog 2-3 teev. Nyob rau tib lub sijhawm, qee qhov dej nag yuav tsum tau ntxiv rau nag lossis daus thiab sib cais.

Tom qab cov tshuaj tiv thaiv, LSACa yuav tsum tau crystallized thiab sib cais kom tau ib yam khoom uas muaj purity siab dua. Cov txheej txheem sib cais crystallization yuav tsum tswj hwm yam xws li crystallization tej yam kev mob thiab kev xaiv hnyav los txhim kho qhov purity thiab tawm los ntawm cov khoom. Feem ntau hais lus, nws yog ib qho tsim nyog yuav tsum tau ntxiv cov dej kom tsim nyog tom qab cov tshuaj tiv thaiv ua kom cov concentration ntawm cov tshuaj tiv thaiv ntawm 10-15%, thiab tom qab ntawd sib sau ua ke thiab crystallize los ntawm nplawm, txias thiab lwm yam txheej txheem. Thaum lub sij hawm crystallization txheej txheem, qee cov crystallization-txhawb cov kuab tshuaj thiab cov khoom ntxiv, xws li methanol, acetone, ethanol, thiab lwm yam, tuaj yeem muab ntxiv rau hauv qhov tsim nyog los txhim kho cov purity thiab siv lead ua ntawm cov khoom.

Hauv kev xaus, cov txheej txheem synthesis ntawmCalcium lignosulfonatekoom nrog ntau yam kev siv thev naus laus zis thiab kev sim tswj, yuav tsum muaj qee yam kev paub txog tshuaj lom neeg thiab kev sim kev txawj ntse, thiab maj mam txhim kho cov kev mob tshwm sim los ntawm kev sim thiab kev sim los txhim kho qhov purity thiab tawm los ntawm cov khoom kom tau raws li daim ntawv thov hauv ntau qhov chaw.
