Qhov sib txawv tseem ceeb ntawm chav distillation thiab hydrodistillation yog tias chav distillation siv chav rau kev rho tawm, hos hydrodistillation siv dej, chav lossis kev sib xyaw ntawm dej thiab chav rau kev rho tawm.
Distillation yog txheej txheem kev lag luam uas suav nrog cov cua sov ntawm cov kua los tsim cov vapor uas tau sau thaum txias cais los ntawm cov kua qub. Cov txheej txheem ntawm distillation tsuas yog siv qhov sib txawv ntawm cov ntsiab lus boiling lossis volatility ntawm cov khoom sib txawv hauv qhov sib tov.
Chav Distillation yog dab tsi?
Chav distillation yog txheej txheem kev lag luam uas suav nrog kev sib cais ntawm cov khoom sib xyaw hauv qhov sib xyaw ua kom sov los ntawm kev ntxiv dej rau lub distillation flask. Cov txheej txheem no muaj txiaj ntsig zoo hauv kev lag luam-teev daim ntawv thov raws li cov txheej txheem purification kom tshem tawm impurities hauv ib qho chaw. Cov khoom ntawm cov khoom sib tov yuav tsum tsis hloov pauv kom ua tiav cov txheej txheem no.
Nyob rau hauv chav distillation, peb muaj peev xwm cais cov Cheebtsam nyob rau hauv sib tov los ntawm vaporizing lawv ntawm boiling point uas yog qis dua lawv qhov tseeb boiling point. Yog tias tsis ua raws li txoj cai no, qee cov khoom yuav decompose ua ntej mus txog qhov kub. Yog tias qhov no tshwm sim, peb tsis tuaj yeem cais lawv kom raug.
Daim duab 01: Chav Distillation Apparatus
Cov txheej txheem ntawm chav distillation suav nrog kev ntxiv dej rau lub khob distillation, qhov sib xyaw kom sib cais. Cov dej yog ntxiv kom txo qis cov ntsiab lus kub ntawm cov khoom. Tom qab ntawd, peb tuaj yeem ua kom sov qhov sib tov thaum agitating nws. Raws li cov kauj ruam no, cov khoom yuav vaporize sai sai. Tom qab ntawd lub vapor siab ntawm lub distillation flask nce. Thaum lub vapor siab tshaj qhov atmospheric siab, qhov sib tov pib boil. Txij li thaum qhov sib tov boils ntawm qis siab (qis dua li atmospheric siab), lub boiling point ntawm lub Cheebtsam kuj poob lawm.
Hydrodistillation yog dab tsi?
Hydrodistillation yog txheej txheem kev lag luam uas tuaj yeem ua tiav siv dej lossis chav dej. Lub npe "hydrodistillation" yog siv los ntawm kev siv dej hauv cov kua los yog daim ntawv vapor. Cov txheej txheem no tau ntev tau siv rau kev rho tawm cov roj tseem ceeb thiab cov tebchaw los ntawm cov ntaub ntawv cog. Muaj peb txoj hauv kev ua qhov kev rho tawm no: dej distillation, dej thiab chav distillation, thiab ncaj qha chav distillation.
Txoj kev ntawm distillation hauv dej distillation yog hydro-diffusion; Txoj kev ntawm distillation hauv dej ntxiv rau chav distillation yog hydrolysis, thaum txoj kev ntawm distillation nyob rau hauv ncaj qha chav distillation yog decomposition los ntawm tshav kub. Thaum peb siv cov nroj tsuag matrix hauv cov txheej txheem ntawm hydrodistillation, dej thiab chav ua haujlwm yog cov xov xwm tseem ceeb rau cov tshuaj dawb bioactive. Feem ntau, cov roj thiab lwm yam bioactive compounds tau los ntawm txoj kev no yog qhuav dhau anhydrous sodium sulfate. Feem ntau, hydrodistillation yog ua ntawm qhov kub siab tshaj qhov kub ntawm cov dej. Vim li no, qee cov khoom tsis haum thiab cov xim ntuj tuaj yeem poob los ntawm cov nroj tsuag matrix.
Qhov txawv ntawm Chav Distillation thiab Hydrodistillation yog dab tsi?
Chav distillation yog hom hydrodistillation. Qhov sib txawv tseem ceeb ntawm chav distillation thiab hydrodistillation yog tias chav distillation siv chav rau kev rho tawm thaum hydrodistillation siv dej, chav lossis kev sib xyaw ntawm dej thiab chav rau kev rho tawm.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm chav distillation thiab hydrodistillation.
Summary – Chav Distillation vs Hydrodistillation
Chav distillation yog hom hydrodistillation. Qhov sib txawv tseem ceeb ntawm chav distillation thiab hydrodistillation yog tias chav distillation siv chav rau kev rho tawm thaum hydrodistillation siv dej, chav lossis kev sib xyaw ntawm dej thiab chav rau kev rho tawm.
