DISTILLATION yog qhov ua kom huv ntawm cov kua los ntawm cua sov rau nws kub point , ua rau vaporization, thiab tom qab ntawd condensing cov vapors mus rau hauv lub xeev ua kua thiab sau cov kua. Kev sib cais ntawm ob lossis ntau dua cov kua yuav tsum muaj qhov sib txawv boiling kub.

Ib yam li ntawd, ib tug yuav nug, dab tsi lub cev khoom siv los cais cov sib tov los ntawm distillation?

Kev sib xyaw ua ke tuaj yeem sib cais siv ntau hom kev kawm. Distillation siv qhov zoo ntawm qhov sib txawv hauv cov ntsiab lus kub . Evaporation tshem tawm cov kua los ntawm kev daws kom tawm hauv cov khoom siv. Lim cais cov khib nyiab ntawm qhov sib txawv.

Ib tug kuj yuav nug, dab tsi tso cai rau ib tug sib tov kom cais distillation? Distillation Txhais Distillation yog ib txoj kev siv dav rau cais cov sib tov raws li qhov sib txawv ntawm cov xwm txheej yuav tsum tau hloov cov theem ntawm cov khoom ntawm lub sib tov . Rau cais a sib tov ntawm cov kua dej, cov kua tuaj yeem ua kom sov rau cov khoom siv, uas muaj cov ntsiab lus kub sib txawv, mus rau theem roj.

Xav txog qhov no, dab tsi yog peb lub cev muaj zog uas tuaj yeem siv los cais cov sib tov?

Cov khoom ntawm lub cev no tuaj yeem yog lub cev lub cev, cov khoom sib nqus thiab cov khoom siv hluav taws xob, qhov tshwj xeeb lub ntiajteb txawj nqus, ntom ntom, melting point, kub point thiab solubility. Nov yog qee qhov kev sib txawv ntawm kev sib cais sib xyaw. Cov tebchaw sib txawv muaj qhov sib txawv ntawm solubility ntawm qhov kub thiab txias.

Lub cev twg yog siv los cais cov tshuaj hauv chromatography?

Chromatography yog ib txoj kev ntawm kev sib cais tawm ntawm cov tshuaj sib tov, uas yog nyob rau hauv cov roj los yog kua daim ntawv, los ntawm kev cia lawv nkag mus maj mam dhau mus rau lwm qhov yam khoom , uas feem ntau yog kua lossis khoom.
