Specification
Citric acid yog ternary acid uas nws ionization tas li ntawm 25 degree yog pK1=3.13; pK{3}}.76; pK3=6.40. Hauv cov kab ke lom neeg uas muaj pH txog 7, ob yam khoom tam sim no yog citrate ions thiab mono-hydrogen citrate ions.

Nws tuaj yeem raug esterified ntawm ib lossis ntau dua ntawm nws peb pawg carboxylic acid los tsim ib qho ntawm ntau hom mono-esters, diesters, triesters, thiab sib xyaw esters.

Daim ntawv thov

Nws yog ib hom txiv hmab txiv ntoo acid, uas tuaj yeem ua kom rov ua dua tshiab ntawm cutin, thiab feem ntau siv rau hauv cov tshuaj pleev ib ce, tshuaj pleev, tshuaj zawv plaub hau, tshuaj pleev ib ce, khoom siv tshuaj tiv thaiv kev laus, khoom siv pob txuv thiab lwm yam. Nws tuaj yeem siv los ua kev sim reagent, chromatographic reagent thiab biochemical reagent hauv tshuaj siv tshuab. Siv raws li tus neeg sawv cev complexing, masking agent; Txhawm rau npaj cov tshuaj tsis haum. Kev siv nws los yog citrate li kev pab ntxhua khaub ncaws tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom siv ntxhua khaub ncaws, tuaj yeem ua rau cov hlau ions sai sai, tiv thaiv cov pa phem los ntawm kev rov qab mus rau hauv cov ntaub, thiab tswj xyuas qhov tsim nyog alkaline ntxuav; Dispersion thiab tshem tawm cov av thiab tshauv; Nws tuaj yeem txhim kho kev ua haujlwm ntawm surfactants thiab yog tus neeg saib xyuas zoo heev. Nws tuaj yeem siv los ua cov reagent los kuaj cov kua qaub ua haujlwm ntawm cov vuas ceramic. Citric acid - Sodium citrate tsis yog siv rau flue gas desulfurization. Citric acid-sodium citrate buffer tov yog ib qho tseem ceeb heev desulphurization absorber vim nws tsis tshua muaj vapor siab, tsis muaj tshuaj lom, ruaj khov khoom thiab siab SO2 nqus.

Nyob rau hauv kev tsim khoom ntawm nws microbial fermentation txoj kev yog siv, thiab tsuas muaj ob peb yam tseem ceeb aspergillus thiab poov xab, cov Aspergillus Niger yog ib tug kev sib tw hom nyob rau hauv kev lag luam, thiab candida lipiolytica thiab monzorrhoeae muaj kev sib tw nyob rau hauv cov poov xab.

Cia: Khaws rau hauv qhov chaw qhuav, txias, thiab ntxoov ntxoo nrog thawj ntim, tsis txhob ya raws, khaws cia ntawm chav tsev kub.
