Ukusetyenziswa
I-Levulinic acid yimveliso ye-biomass kwaye izinto eziphuma kuyo, ezifana ne-ethyl levulinate kunye ne-alkyl levulinate, zingasetyenziswa njengezongezo zamafutha.
I-levulinic acid isetyenziselwa i-calcium levulinate kwi-pharmaceuticals, njengeesters kwi-solvents nakwi-plasticizers, kunye nokwenza i-valerolactone. Njengoko ukusetyenziswa kwayo kukhula, mhlawumbi iya kwenziwa nge-cellulosic waste. I-Mesitonic acid, i-homololog ye-levulinic acid ifunyanwa ngokubilisa i-mesityl oxide ene-KCN.
I-hydrogenation ye-levulinic acid inokuvelisa ezinye iikhemikhali eziluncedo. I-Valeric-g-lactone, eyisinyibilikisi esisebenzayo esisetyenziswa kakhulu, ingafumaneka kwisivuno esiphezulu kakhulu. Le khompawundi inokuba yi-hydrogenated ibe yi-1,4-pentandiol, ethi xa iphelelwa ngamanzi emzimbeni ivelise i-1,3-pentadine (i-piperylene). I-Piperylene yaziwa ngokuyi-polymerize ibe yi-rubber mass kwaye ke ngoko ngumthombo werabha yokwenziwa (Ghorpade kunye noHanna 1997).
I-Levulinic acid sisandulela sokwenziwa kwezinto eziluncedo ezifana ne-γ-valerolactone, i-ethyl levulinate, i-pentanoic acid kunye ne-2-methyl-tetrahydrofuran. Ukuveliswa kunye nokulungiswa kwe-levulinic acid kuphumela kwi-biofuels ezinokubakho.
Ingasetyenziswa kwakhona kwi:
Ukulungiswa kwe-catalytic composite yokwenza i-5-hydroxymethylfurfural kunye ne-furfural.
Ukwenziwa kwevumba lezorhwebo, i-fraistone.
Ukwenziwa kwezinto eziphuma kwi-pyrrolidone nge-reductive amination.
Ukwenziwa okupheleleyo kwe-mycobacterial arabinogalactan.
Ukupakisha
200KG/Idrama okanye ngokweemfuno zomthengi.
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
