Distillation yog tshuaj txheej txheem qhov twg muaj kev sib xyaw ua ke ntawm ob lossis ntau dua cov kua (hu ua "cov khoom siv") nrog cov ntsiab lus kub sib txawv tuaj yeem sib cais los ntawm ib leeg. Tom qab ntawd lub vapor yog nkag mus rau hauv lub condenser, uas ua rau lub vapor txias thiab hloov nws rov qab mus rau hauv cov kua uas hu ua distillate '.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog qhov txheej txheem ntawm distillation?
Cov txheej txheem ntawm distillation pib nrog cua sov cov kua rau boiling point. Cov kua evaporates, tsim ib vapor. Cov vapor yog tom qab ntawd txias, feem ntau dhau los ntawm cov kav dej lossis cov raj ntawm qhov kub qis dua. Yog tias cov tebchaw no muaj cov ntsiab lus kub sib txawv, koj tuaj yeem cais lawv siv distillation.
Qhov thib ob, dab tsi yog ob txheej txheem hauv distillation? Distillation refining muaj ob txheej txheem ntawm distilling thiab condensation reflux. Distillation feem ntau yog nqa tawm hauv distillation kem, gas-kua ob -phase ntws los ntawm kev sib cuag countercurrent, theem kub thiab huab hwm coj hloov.
Tsis tas li ntawd, 3 kauj ruam ntawm distillation yog dab tsi?
Zuag qhia tag nrho txheej txheem ntawm cawv distillation tuaj yeem suav nrog 3 qhov chaw: fermentation, Distillation , thiab Ua tiav.
Dab tsi yog siv rau distillation?
Distillation yog siv cais cov kua dej los ntawm cov khoom tsis muaj hluav taws xob, xws li kev sib cais ntawm cov cawv cawv los ntawm cov khoom fermented, los yog hauv kev sib cais ntawm ob lossis ntau dua cov kua uas muaj cov ntsiab lus kub sib txawv, xws li hauv kev sib cais ntawm cov roj av, roj av, thiab cov roj lubricating los ntawm cov roj crude.

Dab tsi yog qhov zoo ntawm fractional distillation tshaj qhov yooj yim distillation?
Fractional distillation yog qhov ua tau zoo dua hauv kev sib cais cov kev daws teeb meem zoo tshaj plaws rau hauv lawv cov khoom ntshiab dua li qhov yooj yim distillation. rau cov kev daws teeb meem uas sib txawv me ntsis ntawm Raoult txoj cai, txoj kev tseem tuaj yeem siv rau kev sib cais tag nrho
Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb

Dab tsi yog txheej txheem spontaneous thiab non-spontaneous txheej txheem?
Cov txheej txheem spontaneous yog ib qho uas tshwm sim yam tsis muaj kev cuam tshuam ntawm sab nraud. Ib txoj kev uas tsis yog tshwm sim yuav tsis tshwm sim yog tias tsis muaj kev cuam tshuam ntawm sab nraud
Cov txheej txheem twg yog txheej txheem endothermic?
Cov txheej txheem endothermic yog ib qho txheej txheem uas xav tau lossis nqus lub zog los ntawm nws qhov chaw nyob ib puag ncig, feem ntau yog ua kom sov. Nws yuav yog cov txheej txheem tshuaj, xws li dissolving ammonium nitrate hauv dej, lossis cov txheej txheem ntawm lub cev, xws li melting ntawm cov dej khov nab kuab
