Yuav kom tsis txhob poob ntawm cov tshuaj reactants lossis cov kuab tshuaj, lub reflux system yog siv nyob rau hauv order kom condense tej vapors uas ua rau cua sov thiab xa cov condensates rau cov tshuaj tiv thaiv hlab ntsha.
Lub hom phiaj ntawm reflux yog dab tsi?
Boiling cov tshuaj rau lub sijhawm ntev yog qee zaum tsim nyog hauv cov tshuaj lom neeg. Refluxing yog ib qho txheej txheem uas kws tshuaj siv los ua kom sov cov kuab tshuaj yam tsis muaj qhov kub ntawm cov kuab tshuaj tseem ceeb. Cua sov cov tshuaj tiv thaiv rau nws cov boiling point yam tsis muaj ib tug condenser rau ntxiab vapor yuav tsum tau zam.

Loj-scale distillation yees siv lub reflux system kom ua tiav cov khoom tiav tiav. Reflux yog ib feem ntawm tus pej thuam lub condensed overhead kua khoom uas yog cycled rov qab mus rau sab saum toj ntawm lub pej thuam uas nws ntws downwards kom txias thiab condensation ntawm lub upflowing vapors.
Yuav ua li cas thaum reflux?
A reflux apparatus tso cai rau kom yooj yim cua sov ntawm ib qho kev daws teeb meem, tab sis tsis muaj qhov poob ntawm cov kuab tshuaj uas yuav tshwm sim los ntawm cua sov nyob rau hauv ib tug qhib hlab ntsha. Hauv kev teeb tsa reflux, cov kuab tshuaj vapors raug kaw los ntawm lub condenser, thiab cov concentration ntawm reactants tseem nyob tas li thoob plaws hauv cov txheej txheem.
Tus mob reflux tseem ua haujlwm li cas?
Nws ua haujlwm los ntawm txhim kho thiab ua kom pom qhov tsw thiab tsw qab thiab tshem tawm cov tsis xav tau cov tshuaj sulfur hauv thaj tsam loj ntawm tooj liabdome top. Qhov no ua rau ib qho smoother, richer, sweeter tasting ntsuj plig.
