Kushandiswa
Levulinic acid chigadzirwa chebiomass uye zvinobva mairi, zvakaita se ethyl levulinate ne alkyl levulinate, zvinogona kushandiswa semafuta ekuwedzera.
Levulinic acid inoshandiswa mu calcium levulinate mumishonga, se esters mu solvents uye plasticizers, uye mukugadzira valerolactone. Sezvo kushandiswa kwayo kuchiwedzera, ingangove yakagadzirwa kubva mumarara e cellulosic. Mesitonic acid, homololog ye levulinic acid inowanikwa ne boiing mesityl oxide ne KCN.
Kuwedzerwa kwehydrogen kwe levulinic acid kunogona kugadzira mamwe makemikari anobatsira. Valeric-g-lactone, inova solvent inoshanda uye inoshandiswa zvakanyanya, inogona kuwanikwa mugoho guru. Musanganiswa uyu unogona kuiswa hydrogenated kuita 1,4-pentandiol, iyo kana yapera mvura inoburitsa 1,3-pentadine (piperylene). Piperylene inozivikanwa nekuita polymer kuita rabha uye nekudaro ndiyo inogadzira rabha yakagadzirwa (Ghorpade naHanna 1997).
Levulinic acid ndiyo nzira yekutanga mukugadzirwa kwezvinhu zvinobatsira zvakaita seγ-valerolactone, ethyl levulinate, pentanoic acid uye 2-methyl-tetrahydrofuran. Kubviswa kwelevulinic acid uye kuumbwa kwayo kunoguma nemafuta anogona kushandiswa.
Inogona zvakare kushandiswa mu:
Kugadzirwa kwe catalytic composite yekugadzira 5-hydroxymethylfurfural ne furfural.
Kugadzirwa kwekunhuhwirira kwekutengeserana, fraistone.
Kugadzirwa kwezvinogadzirwa ne pyrrolidone kuburikidza ne reductive amination.
Kugadzirwa kwese kwe mycobacterial arabinogalactan.
Kurongedza
200KG/Drum kana zvichienderana nezvinodiwa nevatengi.

Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
