| Kev piav qhia |
2-methylfuran yog cov nplaim taws, dej soluble kua uas muaj peev xwm siv tau los ua lwm yam biofuel. Nws tau dhau los ua qhov txaus nyiam thiab vam meej vim tias tsis ntev los no kev ua tiav hauv nws txoj kev tsim khoom los ntawm lub cev qhuav dej thiab hydrogenolysis ntawm fructose lossis cellulose. Qhov no qhia txog kev cia siab ntawm kev lag luam loj ntawm 2-methylfuran thiab nws cov derivative 2, 5-dimethylfuran. Lub 2-methylfuran thiab 2, 5-dimethylfuran tam sim no tau raug suav hais tias yog ib qho kev xaiv ntawm lwm txoj hauv kev roj rau lub tshuab hluav taws xob hluav taws xob (SI) vim lawv qhov zoo sib xws rau cov roj av. Yog li ntawd, raws li lwm yam bio-fuels, nws nthuav qhia txoj hauv kev los muab cov peev txheej txuas ntxiv txuas ntxiv mus ntxiv thiab daws qhov teeb meem loj ntawm fossil fuel depletion thiab ntiaj teb sov.

| Chemical Properties |
2-Methylfuran yog cov nplaim hluav taws, dej-soluble kua nrog cov ntxhiab tsw qab zib, pom muaj nyob hauv Myrtle thiab Dutch Lavender siv los ua FEMA GRAS (Feem ntau Pom Zoo Raws Li Kev Nyab Xeeb) cov tshuaj tsw qab, nrog rau cov peev xwm siv rau lwm cov roj. 2-Methylfuran yuav tsum tau txais traction nyob rau yav tom ntej vim nws yog siv feem ntau hauv kev lag luam tshuaj. Nws yog lub teeb daj daj ntsuab volatile organic compound nrog cov ntxhiab tsw ethereal thiab tseem hu ua sylvan. 2-Methylfuran hloov nws qhov ntxoov ntxoo rau xim dub lossis daj thaum raug tshav ntuj. Nws yog flammable heev thiab li no yog khaws cia rau hauv ib qho chaw ventilated, txias qhuav qhov chaw deb ntawm tshav kub & hluav taws. |
| Siv |
2-Methylfuran yog siv dav hauv kev tsim tshuaj xws li atropine, sodium acetate, furadantine, anisodamine thiab thiamine furan. Hauv kev lag luam tshuaj, kev sib txuas ntawm vitamin B1 yog ua tiav siv 2-Methylfuran. Nws tsawg dua li dej tab sis nws cov vapors hnyav dua thaum sib piv nrog huab cua. 2-Methylfuran tseem nrhiav tau daim ntawv thov ua ib qho cuab yeej rau kev kuaj mob qog noj ntshav thiab tsim cov tshuaj tiv thaiv malarial xws li chloroquine. Nws kuj yog siv los tsim methyl furfural, aliphatic compounds thiab sulfur thiab nitrogen heterocycles. Ntxiv mus, 2-Methylfuran kuj yog siv los ua tshuaj tua kab, tsw qab los yog tshuaj tsw qab thiab muaj cov nyhuv narcotic. |
| Kev npaj |
2-Methylfuran yog ib tsab xov xwm ntawm kev lag luam (tshuaj nruab nrab) thiab feem ntau yog tsim los ntawm catalytic hydrogenolysis ntawm furfural cawv los yog los ntawm hydrogenation-hydrogenolysis ib ntus los ntawm furfural nyob rau hauv lub vapor theem. |

| Chemical Properties |
Cov kua tsis muaj xim; ntsim, haus luam yeeb aroma |
| Chemical Properties |
2-Methylfuran yog cyclic diene muaj cov khoom zoo li ether. Nws yog reactive heev nrog ntau inorganic thiab organic tebchaw yielding ntau yam tshiab derivatives uas tos kev tshawb nrhiav rau txoj kev loj hlob ntawm kev lag luam daim ntaub ntawv. |
| Qhov tshwm sim |
Tshaj tawm pom nyob rau hauv nqaij nyug siav, qhob cij, butter, nqaij qaib, cocoa, kas fes, currant, mint, tshuaj yej thiab txiv lws suav. |
| Siv |
2-Methylfuran tuaj yeem siv rau hauv kev sib txuas ntawmexo ua-1-methyl-7-oxabicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic anhydride ntawm Diels-Alder cov tshuaj tiv thaiv nrog txiv neej anhydride. |
| Siv |
2-Methylfuran yog ib qho tshuaj tsis haum tshuaj organic (VOCs) siv los ua cov cuab yeej tsis cuam tshuam rau kev kuaj mob qog noj ntshav. |
| Txhais |
ChEBI: 2-methylfuran yog ib tug tswv cuab ntawm chav kawm ntawm furans uas yog furan nyob rau hauv uas cov hydrogen ntawm txoj hauj lwm 2 yog hloov los ntawm ib pawg methyl. Nws muaj lub luag haujlwm raws li tib neeg cov zis metabolite, tus neeg sawv cev hepatotoxic, roj, tus neeg sawv cev flavoring thiab cov nroj tsuag metabolite. Nws yog ib tug tswv cuab ntawm furans thiab volatile organic compound. |
