Short Path Vacuum Distillation

Txoj kev luv lub tshuab nqus tsev distillationyog ib qho kev siv tshuab sib cais, uas feem ntau yog siv rau kev sib cais thiab kev ua kom huv ntawm qhov kub kub los yog cov khoom kub-rhiab heev. Thaum tshav kub kub-sensitive tshuaj yog hais txog cov khoom uas qhia tau hais tias siab rhiab heev thiab yooj yim puas thaum rhuab. Cov tshuaj no yuav hloov lawv lub cev los yog tshuaj lom neeg thaum lawv kub los yog qis. Thaum tshav kub kub-sensitive tshuaj yuav muab faib ua ob pawg:

Cov ntaub ntawv kub-rhiab heev: Thaum cov khoom no raug cua sov, lawv lub cev lub cev yuav hloov pauv loj. Piv txwv li, cov xim kub-rhiab xim tuaj yeem hloov xim raws li qhov sib txawv ntawm qhov kub thiab txias thiab siv dav hauv qhov ntsuas kub thiab ntsuas. Lwm qhov piv txwv yog cov duab nco alloy, uas tuaj yeem hloov nws cov duab rov qab thaum nws raug cua sov, thiab tuaj yeem siv los tsim cov khoom siv uas tau hloov kho qhov kub thiab txias.

Thaum tshav kub kub-sensitive tshuaj: Thaum cov khoom no raug cua sov, lawv cov khoom siv tshuaj yuav hloov tau pom tseeb. Piv txwv li, qee cov organic tebchaw yuav raug tawg, polymerization lossis oxidation ntawm qhov kub thiab txias, ua rau muaj kev hloov pauv hauv cov qauv molecular. Cov yam ntxwv ntawm cov tshuaj tiv thaiv no tuaj yeem siv los npaj cov ntaub ntawv kub-rhiab, tswj tus nqi thiab cov khoom ntawm cov tshuaj tiv thaiv, thiab txawm siv rau kev xa thiab tso tawm cov tshuaj tiv thaiv tshav kub.

Txoj kev luv lub tshuab nqus tsev distillationyuav tsum tau ua nyob rau hauv kev txo qis rau cov laj thawj hauv qab no:

1. Txo qhov kub kub: Nyob rau hauv cov xwm txheej ntawm kev txo qis, lub ambient siab ntawm distillate yog txo, uas ua rau lub boiling point ntawm cov kua. Qhov no tuaj yeem zam qhov kev puas tsuaj ntawm qhov kub thiab txias rau cov khoom kub-rhiab heev thiab txo qhov kub ntawm qhov kub thiab txias. Los ntawm kev txo qhov kub ntawm qhov kub, cov khoom kub kub tuaj yeem sib cais tau zoo.

2. Tiv thaiv cov khoom kub-sensitive: Qee yam khoom tau yooj yim puas, degraded los yog decomposed los ntawm kub kub nyob rau hauv ib txwm siab. Los ntawm distillation nyob rau hauv qhov txo qis, kev sib cais tuaj yeem ua tiav ntawm qhov kub thiab txias, yog li tiv thaiv kev ncaj ncees thiab kev ua haujlwm ntawm cov khoom kub-rhiab.

3. Txo volatilization poob: Raws li kev txo qis, cov khoom tsis haum hauv cov kua yuav yooj yim dua evaporated thiab sau. Piv nrog rau distillation nyob rau hauv ib txwm siab, lub tshuab nqus tsev distillation tuaj yeem txo qhov poob qis thiab txhim kho cov txiaj ntsig thiab purity.

4. Ceev cov txheej txheem sib cais: Lub siab qis yog saws nyob rau hauv lub tshuab nqus tsev distillation, uas ua rau luv luv fractionation txoj kev, me me kub gradient thiab ceev ceev. Qhov no pab txo qis kev sib cuam tshuam thiab kev sib kis ntawm cov khoom sib txuas thiab txhim kho kev sib cais thiab cov khoom purity.

Iav Short Path Distillation

Txoj kev luv lub tshuab nqus tsev distillationyog ib qho kev sib cais tshuab tau zoo, thiab feem ntau muaj ntau txoj hauv kev los sau cov khoom.

Condensation collection method: Qhov no yog ib txoj hauv kev siv ntau tshaj plaws. Nyob rau hauv ib lub tshuab distillation, cov roj evaporated los yog kua yog condensed rov qab mus rau lub xeev ua kua los ntawm ib tug condenser, thiab ces cov condensate yog sau los ntawm ib tug sau lub raj mis los yog thawv. Txoj kev no yog tsim rau cov khoom tsis muaj zog uas tsis tshua muaj kub kub.

Condensation collection method: Rau qee yam khoom uas muaj qhov kub kub los yog cov khoom yooj yim decomposed, condensation collection method yuav tsis haum. Hauv qhov no, txoj kev sau cov coagulation tuaj yeem siv tau. Los ntawm muab qhov chaw txias rau hauv lub condenser, cov roj evaporated lossis kua yog ncaj qha condensed hauv, thiab tom qab ntawd cov condensate tau sau. Nws tuaj yeem tiv thaiv kev ruaj ntseg ntawm cov khoom tsis zoo.

Kev ntxuav thiab sau cov txheej txheem: Rau cov khoom uas muaj qhov tsis muaj zog, kev ntxuav thiab sau cov txheej txheem yuav tsim nyog dua. Nyob rau hauv txoj kev no, cov kuab tshuaj los yog cov kua ua kom txias yog siv los ua ib lub tshuab ntxhua khaub ncaws los ntxuav cov roj los yog cov khoom ua kua rau hauv lub raj mis sau. Txoj kev no yog tsim rau cov tshuaj tsis haum tshuaj.

Khoom theem adsorption sau txoj kev: Rau cov khoom siv los yog cov khoom siv nrog cov khoom adsorption, cov khoom siv theem adsorption sau tuaj yeem siv. Nyob rau hauv txoj kev no, ib qho khoom adsorbent (xws li cov pa roj carbon activated) yog muab tso rau hauv cov khoom siv distillation luv luv, thiab cov khoom siv lub hom phiaj yog sau rau ntawm adsorbent los ntawm adsorption. Tom qab ntawd, lub hom phiaj cov khoom tuaj yeem raug rho tawm los ntawm adsorbent los ntawm centrifugation, hnyav elution thiab lwm txoj hauv kev.

Trap collection method: Qee zaum, lub ntxiab tuaj yeem siv los sau cov khoom distillation. Lub ntxiab feem ntau yog ib qho cuab yeej tsim tshwj xeeb rau kev ntes thiab sau cov pa evaporated lossis kua. Lub ntxiab tuaj yeem txuas nrog lub tshuab luv luv-txoj kev distillation kom ncaj qha sau cov khoom.

Txoj kev luv lub tshuab nqus tsev distillationtau tsim thawj zaug los daws cov teeb meem hauv kev sib cais thiab ntxuav cov tshuaj hauv qee thaj chaw tshuaj thiab lub cev.

Hauv kev sim tshuaj lom neeg thiab lub cev yav dhau los, feem ntau yuav tsum tau cais cov khoom sib txawv ntawm cov khoom sib xyaw lossis cov khoom sib xyaw nrog cov purity siab los ntawm cov khoom siv raw. Cov txheej txheem distillation ib txwm ua tsis tau raws li cov cai no hauv qee kis. Piv txwv li, qee yam khoom yuav muaj cov ntsiab lus kub kub, uas ua rau kub siab hauv cov txheej txheem distillation, thiab kub siab yuav ua rau cov tshuaj tiv thaiv decomposition; Los yog qee yam khoom muaj feem cuam tshuam rau cov teeb meem xws li tsis zoo volatility thiab yooj yim decomposition, uas ua rau cov nyhuv distillation nyob rau hauv lub siab tsis zoo.

Yuav kom kov yeej cov teeb meem no, lub tshuab nqus tsev distillation luv luv tau tsim. Cov cuab yeej no ua ke nrog lub tshuab nqus tsev thiab cov txheej txheem distillation, thiab txo qhov kub ntawm lub hom phiaj los ntawm kev txo qhov siab ntawm qhov system, uas yog, tsim kom muaj ib puag ncig qis hauv lub tshuab distillation. Nyob rau hauv txoj kev no, lub hom phiaj cov khoom tuaj yeem evaporated ntawm qhov kub thiab txias, uas txo qhov kev pheej hmoo ntawm thermal degradation thiab decomposition thiab accelerates tus nqi evaporation.

Txoj kev loj hlob ntawm txoj kev luv luv lub tshuab nqus tsev distillation yog sib cais los ntawm kev nce qib ntawm lub tshuab nqus tsev. Txoj kev loj hlob ntawm lub tshuab nqus tsev thaum ntxov tau ua rau cov kws tshawb fawb los tsim ib qho chaw tsis muaj zog, uas ntxiv dag zog rau kev ua tiav ntawm lub tshuab nqus tsev vacuum luv luv.

Qhov ntxov tshaj plaws luv luv lub tshuab nqus tsev distillation siab tshuab tuaj yeem los ntawm qhov kev thov rau kev sib cais nyuaj hauv kev sim tshuaj thiab lub cev, thiab nws tau pom los ntawm kev tshawb fawb tob thiab kev ua kom zoo ntawm lub tshuab nqus tsev thiab cov ntsiab lus distillation. Lub invention ntawm luv luv lub tshuab nqus tsev distillation muab ib tug npaum, muaj tseeb thiab tswj txoj kev sib cais thiab purifying tshuaj, uas plays ib tug tseem ceeb luag hauj lwm nyob rau hauv txhawb txoj kev loj hlob ntawm chemistry, physics thiab lwm yam hauj lwm.
