Isicelo:

I-Levulinic Acid (i-CAS: i-123-76-2) i-soluble ngokulula emanzini kunye notywala, i-ether organic solvents.I-distillation kuxinzelelo lwe-atmospheric ayiboli, kwaye ukuba ishushu ixesha elide, amanzi ayalahleka ukuze abe yi-γ-lactone engaxutywanga.Yimveliso ye-biomass kunye ne-derivatives yayo, njenge-ethyl levulinate kunye ne-alkyl levulinate, ingasetyenziselwa njengezongezo zepetroli.Isetyenziselwa i-calcium levulinate kwi-pharmaceuticals, njenge-esters kwi-solvents kunye ne-plasticizers, kunye nokwenza i-valerolactone.I-Hydrogenation ye-levulinic acid inokuvelisa ezinye iikhemikhali eziluncedo.I-Levulinic Acid yi-precursor ye-synthesis ye-intermediates eluncedo njenge-γ-valerolactone, i-ethyl levulinate, i-pentanoic acid kunye ne-2-methyl-tetrahydrofuran.I-Derivatization kunye ne-esterification ye-levulinic acid iphumela kwii-biofuels ezinokubakho.
I-Levulinic Acid ingasetyenziselwa njengezinto eziluhlaza zonyango, iziqholo kunye nepeyinti, kwaye isetyenziswe njenge-solvent.Le mveliso inezicelo ezibanzi.I-Levulinic acid ingasetyenziselwa zombini i-carboxylic acid kwaye ingasetyenziselwa njenge-ketone yokuphendula ukwenza iintlobo ezahlukeneyo zeemveliso ngokusebenzisa i-esterification, i-halogenation, i-hydrogenation, i-oxidation dehydrogenation, i-condensation, njl., kubandakanywa i-resin, i-pharmaceuticals, iziqholo, i-solvents, Irabha kunye nezongezelelo zeplastiki, izongezo zokuthambisa, ii-surfactants njalo njalo.Kumashishini amayeza, ityuwa ye-calcium (i-calcium fructose) ingasetyenziselwa inaliti ye-intravenous.Njengeyeza lezondlo, linceda ukunyusa ukubunjwa kwamathambo kunye nokugcina ubumnandi obuqhelekileyo bemithambo-luvo kunye nezihlunu.Ingasetyenziselwa ukuveliswa kwe-indomethacin kunye neehomoni zezityalo.I-Levulinic acid eyenziwe nge-bisphenol acid ingenziwa nge-resin e-soluble yamanzi, esetyenziswe kumashishini ephepha ukuvelisa iphepha lokucoca.I-Levulinic acid nayo iphakathi kwe-pesticides kunye nedayi.
Isetyenziselwa ii-reagents ze-biochemical, kodwa kunye ne-organic synthesis.
I-Levulinic Acid ingasetyenziselwa njengento ebalulekileyo yeekhemikhali ekrwada okanye i-solvents.Ingasetyenziselwa ukwenza iyeza (inaliti efakwa emthanjeni, i-indomethacin, njl. njl.), intlaka (i-bisphenol acid enyibilikayo emanzini), iziqholo (iziqholo okanye iziqholo zecuba), ipeyinti, ipeyinti, izibulali-zinambuzane, kunye nezinto ezixutywayo.Ingasetyenziselwa uphando lwe-biochemical;ukwenziwa kwee-esters kunye neziyobisi.Ikwayi-inhibitor ye-chlorophyll synthesis.
