Isicelo:

I-Levulinic Acid (i-CAS: 123-76-2) incibilika kalula emanzini nasetshwaleni, i-ether organic solvents.I-distillation ku-atmospheric pressure ayiboli neze, futhi uma kushisa isikhathi eside, amanzi ayalahleka abe i-γ-lactone engagcwalisiwe.Iwumkhiqizo we-biomass futhi okuphuma kuyo, njenge-ethyl levulinate ne-alkyl levulinate, ingasetshenziswa njengezithasiselo zikaphethiloli.Isetshenziselwa i-calcium levulinate emithini yemithi, njengama-esters kuma-solvents nama-plasticizers, kanye nokwenza i-valerolactone.I-Hydrogenation ye-levulinic acid ingaveza amanye amakhemikhali awusizo.I-Levulinic Acid iyisandulela sokuhlanganiswa kweziphakathi eziwusizo ezifana ne-γ-valerolactone, i-ethyl levulinate, i-pentanoic acid ne-2-methyl-tetrahydrofuran.I-Derivatization kanye ne-esterification ye-levulinic acid iphumela kuma-biofuels angaba khona.
I-Levulinic Acid ingasetshenziswa njengezinto ezingavuthiwe zemithi, izinongo nopende, futhi isetshenziswe njenge-solvent.Lo mkhiqizo unezinhlelo zokusebenza ezibanzi.I-Levulinic acid ingasetshenziswa kokubili njenge-carboxylic acid futhi ingasetshenziswa njenge-ketone yokusabela ekwenzeni izinhlobo ezihlukahlukene zemikhiqizo ngokusebenzisa i-esterification, i-halogenation, i-hydrogenation, i-oxidation dehydrogenation, i-condensation, njll. izithasiselo zenjoloba nezepulasitiki, izithasiselo zokuthambisa, izithasiselo ezisetshenziswayo nokunye.Embonini yemithi, usawoti wawo we-calcium (i-calcium fructose) ungasetshenziselwa ukujova ngomjovo.Njengomuthi wokudla okunomsoco, kusiza ukukhulisa ukwakheka kwethambo nokugcina ukuthokozela okuvamile kwemizwa nemisipha.Ingasetshenziselwa futhi ukukhiqizwa kwe-indomethacin namahomoni ezitshalo.I-Levulinic acid eyenziwe nge-bisphenol acid ingenziwa nge-resin encibilikayo emanzini, esetshenziselwa imboni yephepha ukukhiqiza iphepha lokuhlunga.I-Levulinic acid iphinde ibe phakathi kwezibulala-zinambuzane namadayi.
Isetshenziselwa ama-reagents e-biochemical, kodwa futhi ne-organic synthesis.
I-Levulinic Acid ingasetshenziswa njengento ebalulekile yamakhemikhali eluhlaza noma ama-solvents.Ingasetshenziselwa ukukhiqizwa kwemithi (umjovo womjovo, i-indomethacin, njll.), inhlaka (i-bisphenol acid encibilika emanzini), izinongo (izinongo noma izinongo zikagwayi), upende, upende, izibulala-zinambuzane, nezinto ezifakwa emanzini.Ingasetshenziselwa ucwaningo lwe-biochemical;ukwenziwa kwama-ester nezidakamizwa.Futhi iyi-inhibitor ye-chlorophyll synthesis.
