Distillation yog cov txheej txheem ntawm cua sov ua kua los tsim vapor uas tau sau thaum txias cais los ntawm cov kua qub. Nws yog nyob ntawm qhov sib txawv ntawm qhov kub kub lossis qhov ntsuas kub ntawm cov khoom. Cov txheej txheem yuav raug siv cais cov khoom sib xyaw ua ke los yog los pab ua kom huv.

Ua raws li qhov xav tau, lub hom phiaj ntawm distillation hauv chemistry yog dab tsi?

Distillation yog siv los purify ib tug compound byseparating nws los ntawm ib tug tsis-volatile los yog tsawg-volatile khoom. Vim cov sib txawv tebchaw feem ntau muaj txawv boiling ntsiab lus, lub Cheebtsam feem ntau cais los ntawm ib tug sib tov thaum lub sib tov yog distilled.

Ib tug kuj yuav nug, dab tsi yog piv txwv ntawm distillation? Piv txwv ntawm Distillation Cov dej ntsev yog hloov mus rau hauv dej tshiab los ntawm distillation .

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog qhov distillate nyob rau hauv yooj yim distillation?

Yooj yim distillation (cov txheej txheem tau teev tseg hauv qab no) tuaj yeem siv tau zoo los cais cov kua dej uas muaj tsawg kawg tsib caug degrees sib txawv hauv lawv cov ntsiab lus kub. Raws li cov kua distilled yog rhuab, cov vapors uas tsim yuav berichest nyob rau hauv lub feem ntawm cov sib tov uas boils nyob rau hauv lub lowesttemperature.

Dab tsi yog fractional distillation hauv chemistry?

Fractional distillation yog kev sib cais ntawm amixture rau hauv nws cov khoom seem, los yog feem. Tshuaj cov tebchaw sib cais los ntawm cua sov lawv mus rau qhov kub ntawm qhov twg lossis ntau qhov feem ntawm qhov sib tov yuav vaporize.
