Nhanganyaya
2,5-Dimethylfuran ndeye organic compound. Izvi zvinotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye2,5-dimethylfuran:
Hunhu:
- Kuonekwa: 2,5-Dimethylfuran imvura isina ruvara ine kunhuhwirira kwakasiyana.
- Solubility: inonyungudika muorganic solvents senge ethanol uye ether, isinganyungudika mumvura.
- Kugadzikana: Yakagadzikana pane tembiricha yekamuri, asi inoda kuchengetedzwa kubva kuchiedza uye kuvharwa.
Shandisa:
- 2,5-dimethylfuran inowanzoshandiswa sechinhu chinonyungudutsa mumakemikari indasitiri, kunyanya kunyungudutsa mapolymer compounds, akadai semapolymers, resins, nezvimwewo.
Nzira:
- 2,5-Dimethylfuran inogona kugadzirirwa nekuita kwe furan ne ethylene. Chekutanga, iyo yekuwedzera reaction yefuran uye ethylene pasi pekuita kweasidhi catalyst inoitwa, uyezve alkali-catalyzed kurongeka kwemaitiro kunoitwa kugadzira 2,5-dimethylfuran.
Zvekuchengetedza
- 2,5-Dimethylfuran inogumbura uye inodhaka, uye inogona kuva nemigumisiro inoshungurudza paganda, maziso, uye maitiro ekufema.
- Chengetedzo dzinofanirwa kutorwa kuitira kuratidzwa, sekupfeka magirovhosi ekudzivirira akakodzera, magirazi uye masks.
- Dzivisa kusangana nemoto, teerera kufefetera paunenge uchichengeta, uye chengeta kure neoxidants.
- Paunenge uchishandisa kana kubata 2,5-dimethylfuran, tevera maitiro akakodzera ekuchengetedza uye udzivise inhalation, kupinza, kana kubata.
