Cyclhexane ntom ntom: Kev Ntsuam Xyuas thiab Kev Siv
Cyclohexane yog ib qho tseem ceeb organic compound dav siv nyob rau hauv kev lag luam tshuaj, tshwj xeeb tshaj yog nyob rau hauv lub synthesis ntawm nylon, kuab tshuaj thiab extractants. Raws li cov kws tshaj lij kev lag luam tshuaj, kev nkag siab txog qhov ceev ntawm cyclohexane thiab nws cov khoom muaj feem xyuam yog qhov tseem ceeb rau kev ua kom zoo dua cov txheej txheem ntau lawm thiab txhim kho cov khoom zoo. Hauv daim ntawv no, peb yuav txheeb xyuas qhov nthuav dav ntawm qhov tseem ceeb ntawm cyclohexane ntom ntom thiab sib tham txog nws qhov tseem ceeb hauv kev siv tswv yim.
Lub tswv yim tseem ceeb ntawm cyclohexane ceev
Cyclohexane (tshuaj formula: C₆H₁₂) yog ib qho saturated cyclohexane hydrocarbon nrog cov kua tsis muaj xim thiab pob tshab. Nws qhov ceev yog qhov loj ntawm ib chav tsev ntim ntawm cyclohexane, feem ntau qhia hauv g / cm³ lossis kg / m³. Ntawm chav tsev kub thiab siab (20 ° C, 1 atm), qhov ceev ntawm cyclohexane yog kwv yees li 0.779 g / cm³. Cov cuab yeej ntawm lub cev no cuam tshuam los ntawm qhov kub thiab txias thiab tuaj yeem sib txawv raws li qhov sib txawv.
Cov nyhuv ntawm qhov kub ntawm qhov ntom ntawm cyclohexane
Kub yog ib qho tseem ceeb tshaj plaws uas cuam tshuam rau qhov ceev ntawm cyclohexane. Raws li qhov kub thiab txias, lub thermal txav ntawm cyclohexane molecules intensifies thiab qhov nruab nrab ntawm qhov deb ntawm molecules nce, uas ua rau ib tug txo nyob rau hauv cov kua. Yog li ntawd, nyob rau hauv kev xyaum, thaum lub kub hloov, nws yog tsim nyog los recalibrate cov khoom siv los xyuas kom meej qhov tseeb ntawm qhov ntsuas thiab cov txheej txheem tsis. Piv txwv li, thaum cov txheej txheem distillation lossis rho tawm tau ua tiav ntawm qhov kub siab, qhov ceev ntawm cyclohexane yuav qis dua tus nqi ntawm chav tsev kub, uas tej zaum yuav muaj qee yam cuam tshuam rau kev sib cais.
Cov nyhuv ntawm lub siab ntawm cyclohexane ntom ntom
Kev kub siab kuj tuaj yeem ua rau muaj kev cuam tshuam loj rau qhov ceev ntawm cyclohexane. Feem ntau, raws li qhov siab nce, qhov kev ncua deb ntawm cov tshuaj txo qis thiab qhov ceev ntawm cov kua nce. Rau cov kua dej xws li cyclohexane, qhov kev hloov pauv ntawm qhov ceev yog qhov me me tshaj qhov kev ua haujlwm siab ua haujlwm. Yog li ntawd, cov nyhuv ntawm lub siab ntawm qhov ceev ntawm cyclohexane yog negligible nyob rau hauv feem ntau daim ntawv thov scenarios. Thaum muaj kev kub ntxhov siab heev, xws li hauv cov txheej txheem tshwj xeeb xws li kev tshem tawm cov kua dej supercritical, cov nyhuv ntawm qhov ceev ntawm qhov ceev yuav tsum tau saib xyuas tshwj xeeb.
Kev siv ntawm Cyclohexane Ceev hauv Kev Lag Luam
Nws yog ib qho tseem ceeb kom nkag siab txog kev siv cyclohexane ntom ntom hauv cov txheej txheem kev lag luam. Vim nws qhov chaw ntom ntom ntom thiab tsis sib xws, cyclohexane feem ntau yog siv nyob rau hauv cov txheej txheem xws li cov kuab tshuaj rho tawm thiab degreeze. Hauv kev tsim cov khoom siv hluavtaws xws li nylon, kev tswj xyuas qhov ceev kom ntseeg tau cov khoom sib xws thiab zoo sib xws. Qhov ceev kuj yog qhov tseem ceeb ntawm kev thauj thiab khaws cia ntawm cyclohexane, cuam tshuam rau lub tank tsim thiab kev ntsuas kev nyab xeeb.

Cyclohexane density yog ib qho kev ntsuas lub cev uas tsis tuaj yeem tsis quav ntsej hauv kev tsim tshuaj. Los ntawm kev nkag siab txog qhov cuam tshuam ntawm qhov kub thiab txias ntawm nws thiab nws qhov tseem ceeb ntawm kev siv hauv kev lag luam, cov txheej txheem tsim khoom tuaj yeem ua kom zoo dua qub thiab cov khoom zoo tuaj yeem txhim kho. Kev ntsuas ceev ceev thiab tswj hauv Cyclohexane-ntsig txog cov txheej txheem yuav coj cov txiaj ntsig kev khwv nyiaj txiag loj thiab kev ua haujlwm thev naus laus zis rau kev lag luam tshuaj.
Cov ntawv no tshawb nrhiav qhov tseem ceeb ntawm cyclohexane ntom thiab nws cov kev sib txawv raws li cov mob sib txawv, thiab yog npaj kom muaj txiaj ntsig rau cov tub txawg koom ua haujlwm.
