Boiling point ntawm cyclohexane: nyob rau hauv-tob tsom xam thiab kev siv
Cyclhexane yog ib qho tseem ceeb ntawm cov khoom siv dav siv hauv kev lag luam tshuaj thiab nws lub cev muaj zog muaj kev cuam tshuam loj rau kev tsim khoom lag luam. Ntawm lawv, qhov kub ntawm qhov kub ntawm cyclohexane yog qhov tseem ceeb, uas yog qhov tseem ceeb rau kev tsim thiab kev ua kom zoo ntawm ntau cov txheej txheem. Hauv daim ntawv no, lub ntsiab lus kub ntawm cyclohexane yuav raug tshuaj xyuas kom meej, thiab nws txoj kev sib raug zoo nrog lwm yam thiab nws qhov tseem ceeb hauv kev siv tswv yim yuav tau tham txog.
Cov ntaub ntawv tseem ceeb ntawm qhov kub kub ntawm cyclohexane
Cyclohexane yog saturated cyclic hydrocarbon nrog cov tshuaj formula C6H12. Nws qhov kub kub ntawm atmospheric siab yog 80.74 ° C. Qhov ntsuas kub qis no ua rau nws yooj yim los tswj cov theem hloov ntawm cov kua thiab gaseous xeev ntawm cyclohexane. Cov cuab yeej no tseem ceeb tshwj xeeb hauv kev tsim tshuaj, tshwj xeeb tshaj yog thaum cov txheej txheem xws li distillation thiab kev sib cais. Kev nkag siab txog cov ntsiab lus kub ntawm cyclohexane tuaj yeem pab tsim cov cuab yeej siv tau zoo thiab kev ua haujlwm hauv cov txheej txheem cuam tshuam.
Kev sib raug zoo ntawm boiling point thiab molecular qauv ntawm cyclohexane
Lub boiling point ntawm cyclohexane feem ntau cuam tshuam los ntawm nws cov qauv molecular. Cyclohexane molecule muaj rau carbon atoms thiab kaum ob hydrogen atoms, uas qhia ib tug ruaj khov hexagonal nplhaib qauv. Vim tias tsuas yog van der Waals rog muaj nyob nruab nrab ntawm cov molecules, cyclohexane muaj qhov kub qis dua li ntau cov polar molecules. Piv nrog rau nws cov qauv zoo sib xws, cyclohexane's nonpolar xwm ua rau qis qis dua li qhov hnyav ntawm cov saw ncaj alkanes. Yog li ntawd, lub boiling point ntawm cyclohexane ua ib qho tseem ceeb uas yuav tsum tau coj mus rau hauv tus account thaum xaiv hnyav los yog teeb tsa cov tshuaj tiv thaiv.
Qhov tseem ceeb ntawm lub boiling point ntawm cyclohexane nyob rau hauv industrial daim ntaub ntawv
Lub rhaub dej kub ntawm cyclohexane ua lub luag haujlwm tseem ceeb hauv ntau yam txheej txheem tshuaj. Piv txwv li, hauv cov txheej txheem petrochemical hydro-refining, cyclohexane feem ntau yog siv los ua cov kuab tshuaj los yog nruab nrab, thiab kev paub txog nws qhov kub thiab txias tuaj yeem pab kho qhov kub thiab txias. Hauv kev ua haujlwm siab ua kua chromatography (HPLC), cyclohexane feem ntau yog siv los ua ib feem ntawm lub xov tooj ntawm tes vim nws qhov kub tsis tshua muaj kub thiab zoo solubility, kom ntseeg tau tias cov kuab tshuaj evaporates sai yam tsis cuam tshuam nrog cov txheej txheem sib cais.
Environmental thiab Safety Considerations rau lub Boiling Point ntawm Cyclohexane
Hauv kev xyaum, kev paub txog qhov kub thiab txias ntawm cyclohexane kuj tseem ceeb rau kev tsim khoom nyab xeeb. Vim nws qhov kub tsis tshua muaj kub thiab tsis hloov pauv, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias, cyclohexane yuav tsum tau saib xyuas tshwj xeeb los tswj nws cov vapor concentration txhawm rau tiv thaiv kev tawg lossis hluav taws. Lub qhov cua zoo yuav tsum tau muab tso rau hauv cov nroj tsuag nrog cov khoom tsim nyog kom paub tseeb tias cyclohexane vapor tsis dhau qhov kev nyab xeeb.
Cov ntsiab lus
Lub ntsiab lus kub ntawm cyclohexane yog ib qho tseem ceeb uas tsis tuaj yeem tsis quav ntsej hauv kev tsim tshuaj thiab kev sim ua haujlwm. Kev nkag siab ntxaws txog nws qhov kub hnyiab tau ua rau cov txheej txheem tsim thiab kev ua kom zoo dua qub, thiab tseem yuav pab kom muaj kev nyab xeeb hauv cov txheej txheem ntau lawm. Hauv kev siv tshuaj lom neeg yav tom ntej, nrog rau kev ua tiav ntawm kev siv thev naus laus zis, kev tshawb fawb thiab kev nkag siab ntawm cov ntsiab lus kub ntawm cyclohexane yuav ua kom tob dua, txhawb kev ua haujlwm zoo thiab kev nyab xeeb dua.
