Cov txheej txheem ua haujlwm ntawm cov cuab yeej distillation feem ntau yog nyob rau qhov sib txawv ntawm cov cua sib cais, yog li cov kua paug ntawm cov txheej txheem ua haujlwm ntawm cov cuab yeej distillation:
1.} Cov ntsiab cai yooj yim
Lub ntsiab lus tseem ceeb ntawm distillation yog siv qhov sib txawv hauv cov kua sib txawv ntawm cov kua sib txawv, thaum cov kua muaj zog los ntawm cov condenser thiab hloov dua siab rov qab rau hauv cov kua, yog li ua tiav sib cais .
2. cua sov thiab vaporization
Thaum lub sij hawm distillation, cov sib tov ua kua yog rhuab kom sov {}}} Cov vapor siab nce mus txog equilibrium nrog sab nraud siab, cov kua pib boil .
{{03. billsation thiab sib cais
Lub vapor yog txias los ntawm condenser thiab hloov rov qab los ntawm cov kua dej npau suav muaj cov khoom siv npau suav muaj ntau dua ntawm cov khoom sib cais uas muaj peev xwm ua kom muaj kev sib cais thiab ua kom huv si ntawm cov kua xyaw ua ke.
4. Tiv thaiv kev ua phem
Thaum lub sij hawm distillation cov txheej txheem, txhawm rau tiv thaiv cov kua los ntawm overheating boiling kom cov pa dej npau taws kom muaj cov kua kom txau tawm .
5. Daim ntawv thov thiab kev faib tawm
Cov khoom siv distillation yog dav siv nyob rau hauv cov roj ua kom zoo, tshuaj thiab lwm yam kev sib cais thiab lwm yam kev sib cais thiab lwm yam kev sib cais ua ke nrog ntau cov ntsiab lus npau npau los ntawm ntau cov kev ua kom zoo nkauj cov txheej txheem .
{{0 {}} siab nqus distillation
Hauv qee cov ntawv thov tshwj xeeb, xws li cais high-boiling tshuaj, thiab kev sib cais ntau dua, thiab yog haum rau kev lag luam xws li tshuaj thiab khoom noj}
Cov ntsiab lus: Cov khoom siv distillation siv qhov sib txawv boiling sib txawv ntawm txhua qhov sib xyaw ua ke yog yooj yim thiab nws yog dav siv nyob rau hauv ntau cov kev lag luam {}}
