Levulinic Acid (CAS: 123-76-2) yog yooj yim soluble hauv dej thiab cawv, ether organic solvents.Distillation ntawm atmospheric siab hardly decomposes, thiab yog rhuab mus ntev, dej yuav ploj mus ua unsaturated γ-lactone.Nws yog biomass khoom thiab nws cov derivatives, xws li ethyl levulinate thiab alkyl levulinate, tuaj yeem siv los ua roj ntxiv.Nws yog siv rau calcium levulinate nyob rau hauv pharmaceuticals, raws li esters nyob rau hauv cov kuab tshuaj thiab plasticizers, thiab ua valerolactone.Hydrogenation ntawm levulinic acid tuaj yeem tsim lwm yam tshuaj muaj txiaj ntsig.Levulinic Acid yog ib qho ua ntej rau kev sib txuas ntawm cov khoom siv nruab nrab xws li γ-valerolactone, ethyl levulinate, pentanoic acid thiab 2-methyl-tetrahydrofuran.Derivatization thiab esterification ntawm levulinic acid ua rau muaj peev xwm biofuels.
Levulinic Acid tuaj yeem siv los ua cov khoom siv raw ntawm cov tshuaj, txuj lom thiab xim, thiab siv los ua hnyav.Cov khoom no muaj kev siv dav.Levulinic acid tuaj yeem siv los ua ob qho tib si carboxylic acid thiab tseem tuaj yeem siv los ua ketone rau cov tshuaj tiv thaiv rau kev ua ntau yam khoom los ntawm esterification, halogenation, hydrogenation, oxidation dehydrogenation, condensation, thiab lwm yam, nrog rau cov resins, tshuaj, txuj lom, kuab tshuaj, roj hmab thiab yas additives, lubricants additives, surfactants thiab hais txog.Hauv kev lag luam tshuaj, nws cov calcium ntsev (calcium fructose) tuaj yeem siv rau kev txhaj tshuaj rau hauv cov hlab ntsha.Raws li cov khoom noj khoom haus, nws pab txhawb kev tsim cov pob txha thiab tswj qhov kev ua kom zoo ntawm cov hlab ntsha thiab cov leeg.Nws tuaj yeem siv rau kev tsim cov tshuaj indomethacin thiab cov tshuaj hormones cog.Levulinic acid tsim bisphenol acid tuaj yeem ua los ntawm cov dej-soluble resin, siv hauv kev lag luam ntawv los tsim cov ntawv lim.Levulinic acid kuj yog ib qho nruab nrab ntawm cov tshuaj tua kab thiab dyes.
Siv rau biochemical reagents, tab sis kuj rau cov organic synthesis.
Levulinic Acid tuaj yeem siv los ua cov khoom siv tshuaj tseem ceeb lossis cov kuab tshuaj.Nws tuaj yeem siv rau kev tsim cov tshuaj (xws li txhaj tshuaj, indomethacin, thiab lwm yam), resin (bisphenol acid water-soluble resin), spices (spices los yog haus luam yeeb txuj lom), xim, xim, tshuaj tua kab, thiab surfactants.Nws tuaj yeem siv rau kev tshawb fawb biochemical;kev tsim cov esters thiab tshuaj.Nws tseem yog tus inhibitor ntawm chlorophyll synthesis.
