Qhov sib txawv tseem ceeb ntawm molecular distillation thiab txoj kev luv luv distillation yog tias molecular distillation siv lub tshuab nqus tsev tsis tshua muaj siab thiab nws yog hom txheej txheem luv luv distillation, whereas luv txoj kev distillation yog cov txheej txheem analytical thiab ib hom distillation uas tso cai. tus qauv mus taug kev luv luv ntawm kev txo siab.

Molecular distillation yog ib qho kev tshuaj ntsuam xyuas thiab ib hom kev luv luv lub tshuab nqus tsev distillation uas siv lub tshuab nqus tsev tsis tshua muaj siab. Cov txheej txheem no tseem siv cov molecular tseem. Txoj kev luv luv distillation yog cov txheej txheem analytical thiab ib hom distillation uas tso cai rau tus qauv taug kev luv luv ntawm kev txo qis.

Molecular Distillation yog dab tsi?

Molecular distillation yog ib qho kev tshuaj ntsuam xyuas thiab ib hom kev luv luv lub tshuab nqus tsev distillation uas siv lub tshuab nqus tsev tsis tshua muaj siab. Cov txheej txheem no siv cov molecular tseem. Lub tshuab nqus tsev siab uas siv rau cov txheej txheem no yog tsawg li 0.01 torr lossis qis dua. Cov txheej txheem no yog qhov tseem ceeb hauv kev sib cais cov khoom sib xyaw, hauv cov txheej txheem purification, thiab hauv cov ntsiab lus ntawm cov khoom ntuj tsim. Ntxiv mus, peb tuaj yeem siv molecular distillation rau cov khoom ntuj tsim, cov tebchaw nyuaj, thiab thermally rhiab molecules xws li cov vitamins thiab polyunsaturated fatty acids.

Molecular distillation cuam tshuam rau lub sijhawm luv luv ntawm cov kua distillate rau qhov kub thiab txias hauv qab lub tshuab nqus tsev siab uas tuaj yeem pom hauv kab distillation. Nws muaj qhov deb me me ntawm cov evaporator thiab lub condenser, uas yog li 2 cm. Hauv cov txheej txheem no, cov kua dej yog nyob rau hauv lub free molecular flow regime. Piv txwv li, txoj kev tsis pub dawb ntawm cov molecules yog piv rau qhov loj ntawm cov khoom siv.

Daim duab 01: Distillation ntawm Laboratory

Feem ntau, cov roj theem tsis ua rau muaj kev kub ntxhov rau cov khoom uas yuav evaporate. Yog li ntawd, tus nqi ntawm evaporation tsis nyob ntawm qhov siab. Tsis tas li ntawd, kev txav ntawm cov molecules los ntawm kem yog nyob rau hauv txoj kab ncaj nraim ntawm qhov pom. Qhov no yog vim tias cov molecules tsis tsim cov roj txuas ntxiv lawm. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum muaj txoj hauv kev luv luv ntawm qhov kub thiab txias. Feem ntau, qhov no tau txais los ntawm kev ncua lub phaj kub npog nrog zaj duab xis pub, uas muab tso rau ntawm ib sab ntawm lub phaj txias uas muaj kab pom nyob nruab nrab ntawm.

Qhov txiaj ntsig tseem ceeb ntawm cov txheej txheem no yog lub peev xwm kom tsis txhob muaj teeb meem ntawm toxicity uas tshwm sim vim cov kuab tshuaj uas peb tau siv hauv cov txheej txheem no ua cov neeg ua haujlwm sib cais. Ntxiv mus, lwm qhov txiaj ntsig tseem ceeb yog txo qis qhov poob vim thermal decomposition, uas tuaj yeem pab tau hauv cov txheej txheem pub noj tas mus li. Qhov no tso cai rau sau cov distillate yam tsis muaj kev so hauv lub tshuab nqus tsev.

Industrially, molecular distillation yog ib qho tseem ceeb hauv cov roj purifying, enriching borage roj hauv gamma linoleic acid, thiab rov qab tocopherols los ntawm deodorizer distillate ntawm soybean roj.

Txoj Kev Luv Distillation yog dab tsi?

Txoj kev luv luv distillation yog cov txheej txheem tshuaj xyuas thiab ib hom distillation uas tso cai rau tus qauv mus rau qhov deb ntawm qhov txo qis. Qhov kev ncua deb no yog luv li 2 cm. Feem ntau, hom kev luv luv distillation txheej txheem no muaj ntau lub npe. Lub npe nyob ntawm cov chaw tsim khoom ntawm lub kaw lus thiab cov tebchaw uas yuav tsum tau distilled siv qhov ntsuas no. E.g. distillation nrog cov distillate taug kev los ntawm ib lub iav qhov muag mus rau lwm qhov (uas tsis xav tau ib qho condenser cais ob chav).

Daim duab 02: Qhov sib txawv ntawm txoj kev luv luv lub tshuab nqus tsev distillation; 1. Lub lauj kaub tseem, 2. Cov ntiv tes txias 3. Cov dej txias tawm 4. Cov dej txias hauv 5. Nqus inlet 6. Distillate flask.

Feem ntau, txoj kev luv luv distillation yog qhov tseem ceeb rau cov tebchaw uas tsis ruaj khov ntawm qhov kub thiab txias thiab tseem cais thiab ntxuav cov khoom me me. Qhov txiaj ntsig tseem ceeb ntawm kev siv cov txheej txheem kev ntsuas no yog qhov ntsuas kub ntawm qhov ntsuas kub tuaj yeem txo qis ntawm kev txo qis piv rau qhov kub ntawm cov kua dej (ntawm tus nqi siab tus nqi). Ntxiv mus, lub distillate yuav tsum tau mus tsuas yog ib tug me me nrug ua ntej lub condensation txheej txheem. Kev siv txoj kev luv luv tuaj yeem ua kom qhov poob ntawm tsuas yog me me ntawm cov khoom sib txuas ntawm ob sab ntawm lub cuab yeej. Ib qho piv txwv zoo yog cov txheej txheem Kugelrohr distillation.

Dab tsi yog qhov txawv ntawm Molecular Distillation thiab Short Path Distillation?

Qhov sib txawv tseem ceeb ntawm molecular distillation thiab txoj kev luv luv distillation yog tias molecular distillation siv lub tshuab nqus tsev tsis tshua muaj siab thiab nws yog hom txheej txheem luv luv distillation, whereas luv txoj kev distillation yog cov txheej txheem analytical thiab ib hom distillation uas tso cai. tus qauv mus taug kev luv luv ntawm kev txo siab.

Cov lus hauv qab no qhia txog qhov sib txawv ntawm molecular distillation thiab txoj kev luv luv distillation.

Summary – Molecular Distillation vs Short Path Distillation

Qhov sib txawv tseem ceeb ntawm molecular distillation thiab txoj kev luv luv distillation yog tias molecular distillation siv lub tshuab nqus tsev tsis tshua muaj siab thiab nws yog ib hom kev luv luv distillation txheej txheem, hos txoj kev luv distillation yog cov txheej txheem kev tshuaj xyuas thiab ib hom distillation uas tso cai. tus qauv mus taug kev luv luv ntawm kev txo siab.
