(Lab) Kev Distillation

Kev taw qhia

Short-path distillation yog ib txoj kev sib cais tshiab uas ua rau cov teeb meem sib txawv uas tsis muaj kev sib txig sib txig sib xyaw. Cov kev sib txig ntawm txoj kab sib txawv yog qhov tseeb ntawm lub condenser nyob nruab nrab ntawm cov txuam zaj dab neeg, thiab cov khoom siv ua kua thiab cov txheej txheem yog ua tiav nyob rau hauv tib evaporation chamber.

Tus qauv thiab yam ntxwv

1.Nyob rau hauv lub hauv paus ntawm cov khoom pov thawj hauv tsev (scraper evaporator). Thaum cov dej sib tov sib xyaw ua ke mus rau ib qho chaw nrug tom qab pub mis sib xyaw, lub condenser yog condensed rau hauv cov kua thiab sib cais, thiab cov khoom hnyav faib hauv phab ntsa. Txij thaum lub teeb khoom vapor theem hauv condensed ntxiv hauv, qhov nqus siab nqus yog me me kom muaj lub siab nqus hauv cov cuab yeej.

2. Ua lub siab nqus

3. Qhov kub ntawm lub ntsuas kub yog qhov tsawg tshaj li qhov ntsuas ntawm qhov khoom

4. Cov khoom sib cais ntawm cov ntxhiab: Cov kev sib cais ntawm qhov sib tov yog pom tau vim qhov sib txawv ntawm txoj hauv kev sib txawv ntawm ntau hom kev molecular khiav kua ntws, thiab tsis tas yuav kub hnyiab, yog li qhov evaporation txias ntawm cov khoom nyob rau hauv evaporator yog ib nyuag qis tshaj qhov khoob qhov chaw.Lub theoretical boiling point ntawm cov khoom nyob rau hauv cov neeg mob.

5. Tshawb fais fab ntawm cov dej khov muaj sij hawm luv cua sov

6. Hloov tau huab hwm coj hloov thiab qhov hloov ntawm cov cua kub hloov

Zoo Tshaj Plaws

1.Huab nqus, sib txig sib txig sib luag, tsawg lub sijhawm nyob, ua kom muaj kev puaj phais, evnrhav nrig.

2. Rau qhov sib cais ntawm qhov siab, kev kub npau npau thiab cov cua kub thiab oxide yooj yim cov khoom, muaj kev ywj siab zoo los ntawm kev siv cov paib kom tau cov qoob loo thiab cov khoom zoo dua.

3. Cheem-txoj kev ua kom tsis zoo tsuas yog tshem tawm cov tshuaj tsis haum cov kua hauv cov dej, xws li cov organic solvents, ntxhiab, thiab lwm yam., Tiam sis kuj xaiv cov xim yam khoom kom tshem tawm lwm hom khoom, yog li nws yog ib qho kev tiv thaiv thiab cov khoom xa rov qab zoo.

4. Txwv tsis pub muaj kev sib to taub muaj peev xwm ua tau lub cev tsis muaj peev xwm ua tau los ntawm txoj kev sib cais ua ke. Yog li ntawd, nws yog siv los ua ib qho kev deodorization, decolorization thiab purification hauv kev sib cais ntawm qee cov khoom muaj nqi.

5. Lub phab ntsa ntawm cov evaporator yog nws tus kheej-tu, nrog tsawg pa phem thiab ntxuav yooj yim.
