Taw qhia
2,5-Dimethylfuran yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2,5-dimethylfuran:
Zoo:
- Cov tsos mob: 2,5-Dimethylfuran yog cov kua tsis muaj xim nrog cov ntxhiab tsw.
- Solubility: soluble nyob rau hauv cov organic solvents xws li ethanol thiab ether, insoluble nyob rau hauv dej.
- Stability: Nws yog qhov ruaj khov ntawm chav tsev kub, tab sis nws yuav tsum tau tiv thaiv los ntawm lub teeb thiab kaw.
Siv:
- 2,5-dimethylfuran feem ntau yog siv los ua cov kuab tshuaj hauv kev lag luam tshuaj, tshwj xeeb tshaj yog rau dissolving polymer tebchaw, xws li polymers, resins, thiab lwm yam.
Txoj kev:
- 2,5-Dimethylfuran tuaj yeem npaj los ntawm cov tshuaj tiv thaiv furan nrog ethylene. Ua ntej, qhov sib ntxiv ntawm furan thiab ethylene nyob rau hauv qhov kev txiav txim ntawm cov kua qaub catalyst yog nqa tawm, thiab tom qab ntawd cov tshuaj tiv thaiv alkali-catalyzed yog nqa tawm los tsim 2,5-dimethylfuran.
Cov ntaub ntawv kev nyab xeeb:
- 2,5-Dimethylfuran yog irritating thiab narcotic, thiab tej zaum yuav muaj teeb meem rau ntawm daim tawv nqaij, qhov muag, thiab ua pa system.
- Yuav tsum ceev faj kom raug, xws li hnav hnab looj tes tiv thaiv, tsom iav, thiab qhov ncauj qhov ntswg.
- Tsis txhob sib cuag nrog hluav taws, xyuam xim rau qhov cua thaum khaws cia, thiab kom deb ntawm oxidants.
- Thaum siv lossis tuav 2,5-dimethylfuran, ua raws li cov txheej txheem kev nyab xeeb thiab tsis txhob nqus, noj, lossis tiv tauj.
