Raws li ib qho ntawm cov kws tshaj lij manufacturers ntawm nto moo hom '4A Molecular Sieve, peb sov siab txais tos koj mus yuav cov 4a molecular sieves rau purification ntawm cov kab dej hauv n-hexanol hnyav hauv Tshuag los ntawm peb. Tus nqi qis thiab kev pabcuam zoo tom qab muag yuav raug muab.

molsieve-2

N-hexanol yog cov kua tsis muaj xim thiab pob tshab nrog lub aroma tshwj xeeb. Nws cov qauv molecular yog CH3 (CH2) 5OH. Nws yog siv los ua cov organic hnyav thiab cov organic synthesis raw khoom, kev tsim tshuaj thiab kev npaj tsw.

Yuav kom tau txais anhydrous n-hexanol, cov kev siv feem ntau yog:

1. Distillation: Ua kom zoo dua qhov sib txawv ntawm qhov kub ntawm n-hexanol, uas yog hais txog 157.88 degree thiab lub boiling point ntawm lwm yam impurities, nws yog sib cais los ntawm ib tug distillation ntauwd kom tau n-hexanol nrog me ntsis siab purity.

2. Kev kho Molecular sieve: Siv cov khoom adsorption ntawm molecular sieves, kab dej hauv n-hexanol raug tshem tawm. Txoj kev no tuaj yeem tau txais anhydrous n-hexanol nrog purity siab heev.

Cov lus ceeb toom ntawm kev siv molecular sieves:

1. Xaiv molecular sieves: Ua ntej, koj yuav tsum xaiv ib tug haum molecular sieve. Rau kev tshem tawm dej los ntawm n-hexanol, feem ntau sivmolecular sievehom muaj xws li 3A thiab 4A, uas muaj peev xwm adsorption siab, tshwj xeeb tshaj yog rau cov dej molecules.

2. Tsim kom muaj ib qho system: Raws li kev sim lossis kev tsim khoom, tsim kom muaj lub kaw lus nrog rau n-hexanol cia tank, molecular sieve adsorption kem, ib lub thawv ntim khoom, thiab cov kav dej thiab li qub. Xyuas kom tseeb tias txhua qhov chaw txuas nrog nruj yam tsis muaj qhov xau.

3. Filling molecular sieve: Sau cov molecular sieve tusyees thiab nruj nreem rau hauv adsorption kem kom nws cov nyhuv adsorption.

4. n-hexanol pub mis: maj mam qhia n-hexanol rau hauv kab adsorption los ntawm cov kav dej. Thaum lub sij hawm inflow txheej txheem, tus nqi ntws yuav tsum tau tswj kom tsis txhob muaj lub sij hawm sib cuag ntawm n-hexanol thiab molecular sieve yog luv luv los yog ntev dhau lawm, uas yuav cuam tshuam rau cov nyhuv adsorption.

5. Cov txheej txheem adsorption: Thaum n-hexanol dhau los ntawm kab adsorption, cov kab dej hauv nws yuav raug adsorbed los ntawm molecular sieve. Raws li lub peev xwm adsorption ntawm molecular sieve thiab cov ntsiab lus dej hauv n-hexanol, lub sij hawm sib cuag ntawm n-hexanol thiab molecular sieve yuav tsum tau khaws cia rau ib lub sij hawm.

6. Sau anhydrous n-hexanol: Tom qab adsorption los ntawm molecular sieve, feem ntau ntawm cov dej nyob rau hauv n-hexanol raug tshem tawm, thiab anhydrous n-hexanol tuaj yeem sau tau rau lub sijhawm no.
