Qhov sib txawv tseem ceeb ntawm reflux thiab soxhlet extraction yog tias reflux extraction tsuas muaj ib lub raj mis thiab txias saum toj no, whereas soxhlet extraction muaj ib tug tshwj xeeb apparatus hu ua lub soxhlet extractor.

Reflux yog cov txheej txheem kev tshuaj xyuas uas cuam tshuam nrog kev sib xyaw ntawm cov vapors thiab rov qab los ntawm cov condensate rau lub kaw lus los ntawm cov condensate originated. Soxhlet extraction yog ib qho kev tshuaj xyuas kev rho tawm uas siv cov extractor tshwj xeeb hu ua soxhlet extractor, uas muaj txiaj ntsig zoo rau lub hom phiaj distillation.

Relux Extraction yog dab tsi?

Reflux extraction yog cov txheej txheem kev tshuaj xyuas uas cuam tshuam nrog kev sib xyaw ua ke ntawm cov vapors thiab rov qab los ntawm cov condensate rau lub kaw lus uas cov condensate tau pib. Cov txheej txheem no muaj txiaj ntsig zoo hauv cov ntawv thov kev lag luam thiab cov chaw sim uas siv cov distillation. Ntxiv mus, cov txheej txheem no muaj txiaj ntsig zoo hauv chemistry los muab lub zog txhawm rau ua kom muaj kev cuam tshuam rau lub sijhawm ntev.

Daim duab 01: Ib qho Kev Rov Qab Los

Hauv cov txheej txheem kev lag luam distillation, reflux yog qhov tseem ceeb rau cov kab loj loj distillation thiab rau cov fractionators, suav nrog cov roj av refineries, petrochemical nroj tsuag, tshuaj nroj tsuag, thiab natural gas processing plant.

Hauv cov ntawv thov kev sim, peb tuaj yeem tso cov tshuaj reactants thiab cov kuab tshuaj sib tov rau hauv lub khob hauv qab. Tom qab ntawd, peb tuaj yeem txuas nws mus rau ib qho dej txias condenser uas feem ntau qhib rau huab cua nyob rau saum toj. Tom qab ntawd, lub khob hauv qab yog rhuab, cia lub boiling ntawm cov tshuaj tiv thaiv sib tov. Cov vapor uas tsim los ntawm qhov sib xyaw ua ke dhau los ntawm lub condenser, yog li rov qab mus rau lub khob hauv qab hauv qab gravitation. Cov txheej txheem no yog ib qho tseem ceeb vim tias nws tuaj yeem ua kom lub zog ua kom cov tshuaj tiv thaiv los ntawm kev ua cov txheej txheem ntawm qhov siab thiab tswj qhov kub ntawm qhov chaw siab tsis txhob poob ntau qhov sib tov.

Soxhlet Extraction yog dab tsi?

Soxhlet extraction yog ib qho kev tshuaj xyuas kev rho tawm uas siv cov extractor tshwj xeeb hu ua soxhlet extractor uas muaj txiaj ntsig zoo hauv cov hom phiaj distillation. Lub soxhlet extractor yog ib lub chaw soj ntsuam apparatus invented los ntawm Franz von Soxhlet nyob rau hauv 1879. Ameslikas, lub apparatus no yog tsim los extract lipid los ntawm ib tug khoom khoom. Qhov tseem ceeb tshaj, txoj kev no yuav pab tau thaum muaj kev txwv tsis pub solubility ntawm qhov xav tau hauv cov kuab tshuaj thiab thaum lub impurity tsis soluble hauv cov kuab tshuaj. Tsis tas li ntawd, cov txheej txheem no tuaj yeem tso cai rau kev ua haujlwm tsis muaj kev saib xyuas thiab tsis muaj kev tswj hwm nrog rau kev rov ua dua ntawm cov kuab tshuaj me me txhawm rau txhawm rau yaj cov khoom loj.

Daim duab 02: Ib qho yooj yim Soxhlet Extractor

Muaj peb qhov tseem ceeb ntawm lub tshuab soxhlet: percolator, thimble, thiab siphon. Lub percolator yog ib qho tseem ceeb raws li ib tug boiler thiab reflux uas yuav circulate cov kuab tshuaj. Lub thimble feem ntau yog ua los ntawm cov ntawv lim tuab thiab tuaj yeem khaws cov khoom uas peb yuav rho tawm. Thaum kawg, lub siphon yog ib feem uas ntuav lub thimble.

Qhov txawv ntawm Reflux thiab Soxhlet Extraction yog dab tsi?

Reflux thiab soxhlet extraction yog cov txheej txheem kev lag luam tseem ceeb uas muaj txiaj ntsig zoo hauv kev siv distillation. Qhov sib txawv tseem ceeb ntawm reflux thiab soxhlet extraction yog tias reflux extraction tsuas yog ib lub raj mis thiab txias saum toj no, hos soxhlet extraction muaj ib qho tshwj xeeb apparatus hu ua soxhlet extractor.

Cov hauv qab no infographic teev qhov sib txawv ntawm reflux thiab soxhlet rho tawm hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.

Summary – Reflux vs Soxhlet Extraction

Reflux yog cov txheej txheem kev tshuaj ntsuam xyuas uas cuam tshuam nrog kev sib xyaw ua ke ntawm cov vapors thiab rov qab los ntawm cov condensate mus rau lub kaw lus los ntawm cov condensate tau los. Soxhlet extraction yog ib txoj kev tshuaj xyuas kev rho tawm uas siv cov extractor tshwj xeeb hu ua soxhlet extractor uas muaj txiaj ntsig zoo hauv cov hom phiaj distillation. Qhov sib txawv tseem ceeb ntawm reflux thiab soxhlet extraction yog tias reflux tsuas muaj ib lub raj mis thiab txias saum toj no, whereas soxhlet extraction muaj ib tug tshwj xeeb apparatus hu ua lub soxhlet extractor.
