Taw qhia
2-nn-pentylfuran yog cov organic compound. Cov hauv qab no yog kev qhia txog qee yam ntawm cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2-nn-pentylfuran:
Zoo:
- Cov tsos: cov kua tsis muaj xim
- Solubility: soluble hauv cawv thiab ether, insoluble hauv dej
- Cov khoom siv tshuaj: rhiab heev rau oxidants thiab muaj zog acids, nquag rau cov tshuaj tiv thaiv polymerization
Siv:
- 2-nn-pentylfuran feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis thiab cov ntaub ntawv tshawb fawb
- Vim nws cov cuab yeej adsorption pom tseeb, nws tau siv dav hauv cov xim thiab cov xim dej khib nyiab
Txoj kev:
2-nn-pentylfuran tuaj yeem npaj los ntawm:
- 2-nn-pentylfuran tau txais los ntawm cov tshuaj tiv thaiv ncaj qha ntawm alkynypropylberyllium thiab n-pentylene cov tshuaj tiv thaiv, thiab tom qab ntawd txo cov tshuaj tiv thaiv kom tau txais 2-nn-pentylfuran.
- 2-ammonium sulfate 5-hydroxypentanone yog tsim los ntawm cov tshuaj tiv thaiv ntawm 2-pentenone thiab ammonium sulfate, thiab ces 2-n-pentylfuran yog tau los ntawm cua sov thiab lub cev qhuav dej.
Cov ntaub ntawv kev nyab xeeb:
- 2-Nn-pentylfuran muaj cov khoom ua kom khaus thiab qhov muag puas, yog li tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag thaum siv nws.
- Kev ntsuas cua zoo yuav tsum tau ua thaum siv kom tsis txhob nqus cov pa.
- Nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav, zoo-ventilated, deb ntawm hluav taws thiab oxidants.
- Thaum tuav thiab khaws cia, thov xa mus rau cov txheej txheem kev nyab xeeb rau cov khoom txaus ntshai thiab pov tseg cov khoom pov tseg kom raug.
