Taw qhia

Pentane. Nws cov khoom yog raws li nram no:

Nws yog miscible nrog ntau cov kuab tshuaj organic tab sis tsis nrog dej.

 

Chemical Properties: N-pentane yog ib qho aliphatic hydrocarbon uas yog nplaim taws thiab muaj qhov taw tes qis thiab autoignition kub. Nws tuaj yeem hlawv hauv huab cua los tsim cov pa roj carbon dioxide thiab dej. Nws cov qauv yog yooj yim, thiab n-pentane yog reactive nrog feem ntau cov organic tebchaw.

 

Kev Siv: N-pentane yog siv dav hauv kev sim tshuaj, kev npaj cov kuab tshuaj thiab cov kuab tshuaj sib tov, thiab tseem yog cov khoom siv tseem ceeb hauv kev lag luam roj av.

 

Txoj kev npaj: n-pentane feem ntau tau los ntawm kev tawg thiab hloov kho hauv cov txheej txheem roj av refining. Cov roj av los ntawm cov khoom tsim los ntawm cov txheej txheem no muaj n-pentene, uas tuaj yeem sib cais thiab huv si los ntawm kev distillation kom tau txais cov ntshiab n-pentane.

 

Cov ntaub ntawv kev nyab xeeb: n-pentane yog cov kua hluav taws xob thiab yuav tsum tau ceev kom deb ntawm cov nplaim taws thiab qhov kub thiab txias. Nws yuav tsum tau siv nyob rau hauv ib qho chaw zoo-ventilated thiab tsis txhob sib cuag nrog cov muaj zog oxidizing agents. Kev raug n-pentane ntev ntev tuaj yeem ua rau tawv nqaij qhuav thiab khaus khaus, thiab yuav tsum tau siv cov kev tiv thaiv tsim nyog xws li hnab looj tes thiab tsom iav. Nyob rau hauv rooj plaub ntawm kev nqus pa los yog kev sib cuag ntawm daim tawv nqaij nrog n-pentane, nrhiav kev pab kho mob tam sim ntawd.
