Levulinic acid
levulinic acid yog ib qho ntawm cov bio-based platform molecules saum toj kawg nkaus uas tuaj yeem hloov mus rau hauv ntau yam tshuaj muaj txiaj ntsig.Nws tuaj yeem tsim los ntawm cov kua qaub catalysis los ntawm cov khoom siv txuas ntxiv, xws li cov suab thaj, lignocellulosic biomass thiab cov khoom pov tseg, cov neeg sib tw txaus nyiam vim lawv cov nplua nuj thiab ib puag ncig. benign xwm. LA kev hloov pauv los ntawm cov khoom lag luam niche mus rau cov tshuaj tsim tawm ntau, txawm li cas los xij, xav kom nws cov khoom lag luam los ntawm cov khoom noj biomass ruaj khov ntawm tus nqi qis, siv cov tswv yim zoo ib puag ncig.
Levulinic acid yog dawb Flake Crystal, flammable, hygroscopic. Soluble hauv dej thiab cawv, ether organic solvents. Distillation ntawm atmospheric siab hardly decomposes, thiab yog rhuab mus ntev, dej yuav ploj mus ua unsaturated Y-lactone. Melting point 37.2 ° C. Kub taw tes 139 ~ 140 ° C (lkPa). Tus txheeb ze ntom ntom yog 1.1335. Refractive index 4396.
Levulinic Acid - Kev siv
Cov khoom no tsuas yog siv los ua cov khoom siv raw rau kev tsim cov resins, tshuaj, txuj lom perfumes thiab coatings. Hauv kev lag luam tshuaj, nws cov calcium ntsev tuaj yeem ua rau hauv cov tshuaj txhaj tshuaj thiab indomethacin, thiab lwm yam. Nws cov esters qis tuaj yeem siv los ua zaub mov tsw thiab haus luam yeeb tsw. Cov bisphenol acid ua los ntawm cov khoom no tuaj yeem tsim cov dej-soluble resin, uas tuaj yeem siv hauv kev lag luam ntawv los tsim cov ntawv lim. Nws kuj tseem siv tau los ua tshuaj tua kab, dyes thiab surfactants. Nws kuj yog siv los ua cov extraction thiab sib cais tus neeg sawv cev rau cov tshuaj tsw qab.
Molecular Formula
Ntim
Cia & tuav
Cov khoom no muaj toxicity tsawg. Nws tau ntim rau hauv cov thawv yas thiab ntxiv dag zog nrog cov rooj ntoo. Khaws rau hauv qhov chaw txias, qhuav thiab ventilated. Nyob deb ntawm qhov hluav taws kub. Raws li cov kev cai ntawm cov tshuaj flammable cia thiab kev thauj mus los.
