Amfani
Levulinic acid samfurin biomass ne kuma ana iya amfani da abubuwan da aka samo daga gare shi, kamar ethyl levulinate da alkyl levulinate, a matsayin ƙarin mai.
Ana amfani da levulinic acid don calcium levulinate a cikin magunguna, a matsayin esters a cikin sinadarai masu narkewa da masu amfani da filastik, da kuma don yin valerolactone. Yayin da amfaninsa ke ƙaruwa, wataƙila za a yi shi daga sharar cellulosic. Ana samun Mesitonic acid, wani nau'in levulinic acid ta hanyar haɗa mesityl oxide tare da KCN.
Haɓaka sinadarin levulinic acid na iya samar da wasu sinadarai masu amfani. Valeric-g-lactone, wanda shine ingantaccen mai narkewa mai amfani da yawa, ana iya samunsa a cikin yawan amfanin ƙasa. Wannan mahaɗin za a iya haɗa shi da hydrogen zuwa 1,4-pentandiol, wanda bayan bushewar ruwa yana samar da 1,3-pentadine (piperylene). An san Piperylene yana yin polymerize zuwa roba mai yawa kuma saboda haka tushen roba ne (Ghorpade da Hanna 1997).
Levulinic acid wani abu ne da ke ƙara wa sinadaran tsaka-tsaki masu amfani kamar γ-valerolactone, ethyl levulinate, pentanoic acid da 2-methyl-tetrahydrofuran ƙarfi. Rarraba sinadarin levulinic acid da kuma esterification na shi yana haifar da man fetur mai yawa.
Haka kuma ana iya amfani da shi a cikin:
Shirye-shiryen hadadden catalytic don hada 5-hydroxymethylfurfural da furfural.
Haɗar ƙamshi na kasuwanci, fraistone.
Haɗa pyrrolidone ta hanyar rage tasirin sinadarai.
Jimillar haɗin mycobacterial arabinogalactan.
