Nov 10, 2023
Tso lus
ACHIEVE CHEM tau pab cov neeg siv khoom nyob sab Europe kom ua tiav cov tshuaj tiv thaiv ntawm distillation cais ntawm pentane thiab toluene hauv qhov project tsis ntev los no. Tom qab kev sib tham tob nrog pab pawg ACHIEVE CHEM, ib qho kev tawg-pov thawj stainless hlau reactor raug xaiv kom tau raws li cov neeg siv khoom xav tau.
Ua ntej pom zoo cov cuab yeej siv tshuaj sib xws, ACHIEVE CHEM tau ua tiav ob qhov kev sim ua tiav los ua kom pom nws qhov kev xav:
Txheej txheem cov ntsiab lus ntawm 1st txheej kev daws teeb meem:
1. Kev sim npaj:
Ua ntej pib qhov kev sim, peb ua kom muaj kev nyab xeeb ntawm ib puag ncig ntawm chav kuaj thiab npaj txhua yam khoom tsim nyog thiab cov tshuaj reagents. Cov cuab yeej muaj xws li 50 litre explosion-proof stainless hlau reactor, distillation khoom, tus pas ntsuas kub, ntsuas siab, thiab lwm yam. Cov reagents muaj xws li toluene thiab tsim nyog auxiliary reagents.
2. Cov kauj ruam sim:
Peb yuav ntxuav lub 50 litre tawg-pov thawj stainless hlau reactor thiab ntxiv ib tug tsim nyog tus nqi ntawm toluene. Tom qab ntawd, peb tso lub reactor rau ntawm cov khoom siv distillation thiab pib cua sov. Thaum cov txheej txheem cua sov, peb saib xyuas qhov kev hloov pauv ntawm qhov kub thiab txias thiab tswj lawv nyob rau hauv qhov tsim nyog. Thaum lub boiling point ntawm toluene mus txog 110.8 degree, peb pib distillation sib cais.
3. Distillation sib cais:
Thaum lub sij hawm distillation txheej txheem, peb tswj qhov kub thiab txias stability thiab saib xyuas cov kev hloov ntawm cov distilled kua. Thaum toluene vapor condenses los ntawm lub condenser, nws tsim cov kua uas ntws rov qab mus rau hauv lub reactor, thaum pentane tawm hauv ib daim ntawv gaseous. Cov txheej txheem no txuas ntxiv mus txog thaum lub toluene nyob rau hauv lub reactor yog kiag li distilled thiab sib cais.
4. Kev txheeb xyuas qhov tshwm sim:
Tom qab distillation thiab sib cais, peb tau ntshiab pentane thiab toluene. Los ntawm kev tshuaj ntsuam xyuas tshuaj thiab spectral ntawm cov qauv sib cais, peb pom tias qhov purity ntawm cov khoom ua tau raws li qhov xav tau thiab tsis muaj kev cuam tshuam los ntawm impurities. Tsis tas li ntawd, peb kuj tau ntsuas thiab sau cov khoom siv lub cev ntawm cov khoom, xws li qhov kub thiab txias, qhov taw tes melting, thiab qhov hnyav molecular, thiab pom tias cov khoom no kuj ua raws li qhov kev cia siab. Los ntawm kev sim cov txheej txheem ntawm thawj cov tshuaj, peb ua tiav cov tshuaj tiv thaiv ntawm distillation cais ntawm pentane thiab toluene, thiab tau txais cov khoom zoo.
Txheej txheem cov ntsiab lus ntawm 2nd txheej kev daws teeb meem:
1. Kev sim npaj:
Zoo li thawj qhov kev daws teeb meem, peb ua kom muaj kev nyab xeeb ib puag ncig hauv chav kuaj thiab npaj txhua yam khoom tsim nyog thiab cov tshuaj reagents ua ntej pib. Cov cuab yeej muaj xws li 50 litre explosion-proof stainless hlau reactor, distillation khoom, tus pas ntsuas kub, lub ntsuas siab, thiab lwm yam. Cov reagents muaj xws li pentane thiab tsim nyog auxiliary reagents.
2. Cov kauj ruam sim:
Peb yuav ntxuav lub 50 litre explosion-proof stainless hlau reactor thiab ntxiv ib tug tsim nyog tus nqi ntawm pentane. Tom qab ntawd, peb pib cua sov ntawm lub reactor. Thaum cov txheej txheem cua sov, peb saib xyuas qhov kev hloov pauv ntawm qhov kub thiab txias thiab tswj lawv nyob rau hauv qhov tsim nyog. Thaum lub boiling point ntawm pentane mus txog 36 degree, peb pib distillation sib cais.
3. Distillation sib cais:
Thaum lub sij hawm distillation txheej txheem, peb tswj qhov kub thiab txias stability thiab saib xyuas cov kev hloov ntawm cov distilled kua. Thaum pentane vapor condenses los ntawm lub condenser, nws tsim cov kua uas ntws rov qab mus rau hauv lub reactor, thaum toluene yog tawm nyob rau hauv ib tug gaseous daim ntawv. Cov txheej txheem no txuas ntxiv mus txog thaum lub pentane nyob rau hauv lub reactor yog kiag li distilled thiab sib cais.
4. Kev txheeb xyuas qhov tshwm sim:
Tom qab distillation thiab sib cais, peb tau txais ntshiab toluene thiab pentane. Los ntawm kev tshuaj ntsuam xyuas tshuaj thiab spectral ntawm cov qauv sib cais, peb pom tias qhov purity ntawm cov khoom ua tau raws li qhov xav tau thiab tsis muaj kev cuam tshuam los ntawm impurities. Tsis tas li ntawd, peb kuj tau ntsuas thiab sau cov khoom siv lub cev ntawm cov khoom, xws li qhov kub thiab txias, qhov taw tes melting, thiab qhov hnyav molecular, thiab pom tias cov khoom no kuj ua raws li qhov kev cia siab. Los ntawm kev sim cov txheej txheem ntawm kev daws thib ob, peb kuj tau ua tiav cov tshuaj tiv thaiv ntawm distillation cais ntawm pentane thiab toluene, thiab tau txais cov khoom zoo.
Kev sib piv ntawm cov kev daws teeb meem:
Hauv kev xaus, ob lub tswv yim muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Qhov kev xaiv ntawm lub phiaj xwm twg yog nyob ntawm cov kev xav tau tshwj xeeb, qhov kev sim, thiab lub hom phiaj ntawm qhov kev sim. Lub tswv yim muab los ntawm ACHIEVE CHEM yog tias cov tshuaj lom neeg uas xav tau kev sib cais distillation muaj cov ntsiab lus kub kub thiab tsis hnov tsw rau kev ua haujlwm kub, thawj cov tshuaj yuav tsim nyog dua. Tab sis yog hais tias cov tshuaj uas yuav tsum tau distillation thiab sib cais muaj qis boiling cov ntsiab lus thiab tsis rhiab rau qis-kub khiav hauj lwm, cov tshuaj thib ob tej zaum yuav haum dua.
Kev xaiv khoom siv sib xws:
Tom qab muab peb cov lus qhia tshaj lij rau cov neeg siv khoom, peb pom zoo kom ACHIEVE CHEM tawg-pov thawj stainless hlau tshuaj tiv thaiv kettle series kom tau raws li lawv cov kev xav tau. Yog vim li cas yog tias lub reactor no tau tsim tshwj xeeb los tswj cov tshuaj tiv thaiv tshuaj, uas tsis yog tsuas yog ua kom cov tshuaj tiv thaiv zoo xwb, tab sis kuj xav txog kev nyab xeeb tag nrho. Cov khoom tawg-pov thawj stainless hlau tuaj yeem tiv thaiv kev tawg thiab tshuaj lom neeg, muab qhov chaw ua haujlwm nyab xeeb rau cov neeg ua haujlwm.
