Ntchito:

Levulinic Acid (CAS: 123-76-2) imasungunuka mosavuta m'madzi ndi mowa, ether organic solvents.Distillation ndi kuthamanga kwa mumlengalenga sikuwola, ndipo ngati watenthedwa kwa nthawi yayitali, madzi amatayika kuti akhale osaturated γ-lactone.Ndi biomass mankhwala ndipo zotumphukira zake, monga ethyl levulinate ndi alkyl levulinate, zitha kugwiritsidwa ntchito ngati zowonjezera mafuta.Amagwiritsidwa ntchito pa calcium levulinate mu mankhwala, monga esters mu solvents ndi plasticizers, ndi kupanga valerolactone.Hydrogenation ya levulinic acid imatha kupanga mankhwala ena othandiza.Levulinic Acid ndi kalambulabwalo wa kaphatikizidwe wapakati zothandiza monga γ-valerolactone, ethyl levulinate, pentanoic acid ndi 2-methyl-tetrahydrofuran.Kutulutsa ndi esterification ya levulinic acid kumapangitsa kuti biofuel itheke.
Levulinic Acid ingagwiritsidwe ntchito ngati zopangira mankhwala, zonunkhira ndi utoto, ndikugwiritsidwa ntchito ngati zosungunulira.Izi zili ndi ntchito zambiri.Levulinic acid ingagwiritsidwe ntchito ngati onse a carboxylic acid ndipo ingagwiritsidwe ntchito ngati ketone yopangira zinthu zosiyanasiyana pogwiritsa ntchito esterification, halogenation, hydrogenation, oxidation dehydrogenation, condensation, etc., kuphatikizapo utomoni, mankhwala, zonunkhira, zosungunulira, mphira ndi pulasitiki zina, mafuta zowonjezera, surfactants ndi zina zotero.M'makampani opanga mankhwala, mchere wake wa calcium (calcium fructose) ukhoza kugwiritsidwa ntchito pobaya mtsempha.Monga mankhwala opatsa thanzi, amathandizira kupititsa patsogolo mapangidwe a mafupa ndikukhalabe ndi chisangalalo chokhazikika cha mitsempha ndi minofu.Itha kugwiritsidwanso ntchito popanga indomethacin ndi mahomoni omera.Levulinic acid yopangidwa ndi bisphenol acid imatha kupangidwa ndi utomoni wosungunuka m'madzi, womwe umagwiritsidwa ntchito m'makampani opanga mapepala kuti apange pepala losefera.Levulinic acid ndi gawo lapakati la mankhwala ophera tizilombo ndi utoto.
Amagwiritsidwa ntchito kwa biochemical reagents, komanso organic synthesis.
Levulinic Acid ingagwiritsidwe ntchito ngati mankhwala opangira mankhwala kapena zosungunulira.Itha kugwiritsidwa ntchito popanga mankhwala (jekeseni wa mtsempha, indomethacin, etc.), utomoni (bisphenol acid-soluble resin), zonunkhira (zonunkhira kapena zonunkhira za fodya), utoto, utoto, mankhwala ophera tizilombo, ndi zowonjezera.Itha kugwiritsidwa ntchito pofufuza zamankhwala am'chilengedwe;kupanga esters ndi mankhwala.Komanso ndi inhibitor ya chlorophyll synthesis.
