Tso lus
Molecular distillation, tsis tu ncua alluded rau liluv txoj kev distillation, yog ib lub tswv yim tshwj xeeb siv hauv kev faib cov khoom sib xyaw raws li qhov sib txawv hauv lawv cov volatilities. Nws tau lees paub dav dav rau nws lub peev xwm los tswj cov ntaub ntawv kub-rhiab heev thiab tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau kev tshawb fawb me me hauv chaw ua haujlwm.
Nkag siab txog "Short Path" Concept
Lo lus "txoj kev luv" hauv atomic refining yog txiav txim siab los ntawm txoj kev npaj ntawm cov cuab yeej refining. Tsis yog txhua yam zoo li cov tswv yim ua kom zoo dua qub, tshem tawm tias cov vapor voyages los ntawm qhov chaw ntawm dissipation mus rau qhov chaw ntawm condensation yog qhov tseem ceeb txo qis.
Qhov kev tsim no txo qis lub sij hawm hauv tsev ntawm cov vapor, uas yog qhov yooj yim rau kev ua kom zoo ntawm cov khoom siv hluav taws xob.
Qhov tseem ceeb ntawm Txoj Kev Luv Distillation rau Me Labs
Cov chaw tshawb fawb me me tsis tu ncua xav tau qhov tseeb thiab tsim khoom hauv lawv cov ntaub ntawv. Txoj kev luv luv refining muaj ob peb cov txiaj ntsig uas kho nrog cov kev cai no:

Txoj Kev Short Path Distillation
Cov txheej txheem muaj cua sov cov sib tov nyob rau hauv lub distillation flask mus rau ib tug kub qhov twg cov yam xav tau pib evaporate. Cov vapor yog sai sai thauj mus rau lub condenser los ntawm txoj kev luv luv, qhov chaw uas nws txias sai heev thiab condensed rov qab rau hauv cov kua.
Kev npaj ntawm Mixture: Cov txheej txheem pib nrog kev npaj ntawm cov crude sib tov uas muaj cov yam xav tau los distilled. Qhov sib tov no feem ntau muab tso rau hauv lub evaporation flask ntawm lubluv txoj kev distillationcuab yeej.
Kev Siv Lub Tshuab Nqus Tsev: Lub tshuab nqus tsev yog siv los txo qhov siab rau qhov system. Qhov no txo qis cov ntsiab lus kub ntawm cov tebchaw hauv qhov sib tov, cia lawv vaporize ntawm qhov kub thiab txias thiab txo qhov kev pheej hmoo ntawm thermal degradation.
Cua sov: Lub evaporation fwj uas muaj cov hmoov sib tov yog rhuab, feem ntau yog siv lub tshuab cua sov los yog da dej. Cov cua sov siv ua rau cov tebchaw nrog cov ntsiab lus qis qis kom vaporize ua ntej, thaum tawm hauv qab cov ntsiab lus kub siab dua thiab cov impurities.
Vaporization thiab Vapor Txoj Kev: Raws li qhov sib tov yog rhuab, vapors nce los ntawm lub evaporation flask thiab nkag mus rau txoj kev luv luv distillation taub hau. Kev tsim ntawm lub taub hau luv luv ua kom ntseeg tau tias cov vapors taug kev luv luv kom ncav cuag lub condenser, txo lub sijhawm rau thermal degradation.
Condensation: Nyob rau hauv lub condenser, cov vaporized tebchaw yog sai txias thiab condensed rov qab mus rau hauv cov kua daim ntawv. Qhov no yog ua tiav los ntawm circulating lub coolant, xws li dej, los ntawm lub condenser tsho. Cov kua condensed yog sau rau hauv ib lub khob tau txais nyob rau hauv qab ntawm lub condenser.
Kev Sau Cov Distillate: Cov condensed distillate, muaj cov purified compounds, yog sau rau hauv lub khob tau txais. Nws yog ib qho tseem ceeb los saib xyuas qhov ntsuas kub thiab kho qhov ntsuas raws li qhov xav tau los xyuas kom pom kev sib cais thiab purity ntawm distillate.
Emptying Residue: Raws li cov distillation zuj zus, cov residue tuaj yeem sau rau hauv lub evaporation flask. Tej zaum nws yuav tsim nyog los ntuav cov seem seem thiab rov ua dua lub khob nrog cov hmoov av tshiab kom txuas ntxiv cov txheej txheem distillation.
Rov qab thiab Kev Ntsuam Xyuas: Thaum lub distillation tiav lawm, cov distillate sau tau tuaj yeem ua tiav, tshuaj xyuas, lossis siv ntau yam kev siv, nyob ntawm qhov xav tau.
