Khoom siv
Levulinic acid muaj ntau yam kev siv. Nws tuaj yeem hnov mob raws li ob qho tib si carboxylic acid thiab ketone, tab tom ua cov txheej txheem xws li esterification, halogenation, hydrogenation, oxidative dehydrogenation, thiab condensation los tsim ntau yam khoom. Cov no muaj xws li resins, tshuaj, tshuaj tsw qab, kuab tshuaj, coatings, inks, roj hmab thiab yas additives, lubricating roj additives, surfactants, thiab lwm yam.
Hauv kev lag luam kws tshuaj, calcium ntsev ntawm nws (calcium fructoconate) tuaj yeem siv los npaj cov tshuaj txhaj tshuaj. Raws li cov khoom noj khoom haus ntxiv, nws pab tsim cov pob txha thiab pab tswj lub cev excitability ntawm cov hlab ntsha thiab cov leeg. 4-Oxovaleric acid kuj tseem siv rau hauv kev tsim cov tshuaj indomethacin thiab cov tshuaj hormones cog.
Cov bisphenol acid muab tau los ntawm nws tuaj yeem siv los tsim cov dej-soluble resins, uas muaj txiaj ntsig zoo hauv kev lag luam ntawv rau kev tsim cov ntawv lim. Tsis tas li ntawd, 4-Oxovaleric acid ua haujlwm nruab nrab hauv kev tsim cov tshuaj tua kab thiab dyes.

FAQ
Q: 4-Oxopentanoic acid ua dab tsi rau daim tawv nqaij?
A: Nws tuaj yeem ua rau mob thiab ua kom tawv nqaij. Nws kuj ua raws li cov tshuaj tua kab mob me me nrog cov tshuaj tua kab mob zoo, tsis muaj kev hloov pauv cov qauv lossis pH ntawm lwm cov khoom xyaw hauv cov khoom. Sodium levulinate, sodium ntsev ntawm 4-Oxopentanoic acid, feem ntau yog siv los ua preservative, txawm hais tias nws siv ntau dua hauv cov khoom noj khoom haus ntau dua li cov tshuaj pleev ib ce.
Q: Puas muaj kev nyab xeeb?
A: Cov Kws Tshaj Lij Tshaj Lij rau Kev Nyab Xeeb Cov Khoom Siv Tshuaj Txhuam Hniav tau xaus lus tias levulinic acid thiab sodium levulinate muaj kev nyab xeeb rau kev siv tshuaj pleev ib ce thaum tsim kom tsis txhob khaus, raws li cov kev coj ua tam sim no ntawm kev siv thiab cov ntsiab lus tau piav qhia hauv kev ntsuam xyuas kev nyab xeeb.
