Taw qhia

Cyclopentane yog cov kua tsis muaj xim nrog cov ntxhiab tsw. Nws yog aliphatic hydrocarbon. Nws yog insoluble hauv dej tab sis tuaj yeem soluble hauv ntau cov kuab tshuaj organic.

 

Cyclopentane muaj qhov zoo solubility thiab zoo heev degreasing zog, thiab feem ntau yog siv los ua cov organic sim hnyav hauv chav kuaj. Nws kuj yog ib qho tshuaj ntxuav uas siv tau los tshem tawm cov roj thiab cov av.

 

Ib txoj hauv kev rau kev tsim cov cyclopentane yog los ntawm dehydrogenation ntawm alkanes. Ib txoj hauv kev yog kom tau txais cyclopentane los ntawm kev faib tawm los ntawm cov roj av tawg.

 

Cyclopentane muaj qee qhov kev pheej hmoo ntawm kev nyab xeeb, nws yog cov kua nplaum uas tuaj yeem ua rau hluav taws kub lossis tawg tau yooj yim. Kev sib cuag nrog cov nplaim taws thiab cov khoom kub kub yuav tsum zam thaum siv. Thaum tuav cyclopentane, nws yuav tsum tau ua kom cua zoo thiab tsis txhob nqus los yog sib cuag nrog daim tawv nqaij thiab qhov muag.
