Physical Properties of Para Xylene

Para xylene (CAS 106-42-3) yog dab tsi?

Para Xylene yog cov kua tsis muaj xim, pob tshab nrog cov ntxhiab tsw ntxhiab tsw. Chemically, nws belongs rau tsev neeg muaj ntxhiab hydrocarbon, nrog ib tug qauv molecular muaj yim carbon atoms thiab kaum hydrogen atoms. Ntawm qhov ntsuas kub thiab qhov siab, p-xylene yog qhov hloov pauv tau yooj yim, insoluble hauv dej, tab sis miscible nrog ntau cov kuab tshuaj organic. Hauv kev lag luam, nws feem ntau yog muab rho tawm los ua ib feem ntawm cov roj av lossis cov thee tar sib tov, xav tau kev sib cais thiab kev ua kom huv si kom ua tiav cov khoom siab tshaj -purity.

Hauv qhov xwm txheej, p-xylene tsis dav dav thiab feem ntau yog los ntawm cov txheej txheem hluavtaws. Nws feem ntau ua ke nrog peb lwm xylene isomers (o-xylene, m-xylene, thiab n-xylene).

Para xylene (CAS 106-42-3) ua li cas?

Kev tsim cov p-xylene feem ntau yog nyob ntawm cov roj av refining thiab chemical processing. Cov roj Crude undergoes distillation thiab cracking los tsim cov khoom nruab nrab uas muaj ntau yam aromatic hydrocarbons. Cov intermediates no tom qab ntawd ua tiav los ntawm kev hloov pauv catalytic lossis chav tawg kom tsim cov xylenes sib xyaw. Vim yog cov ntsiab lus kub kub heev ntawm plaub xylene isomers, cov txheej txheem distillation ib txwm tawm tsam kom ua tiav kev sib cais zoo. Yog li ntawd, kev ua kom huv ntawm p-xylene feem ntau siv crystallization lossis adsorption kev sib cais.

Ntawm cov no, kev sib cais adsorption yog ib qho ntawm cov txheej txheem siv dav tshaj plaws. Txoj kev no siv cov adsorbents tshwj xeeb los xaiv adsorb para-xylene, ua raws li cov kauj ruam desorption kom tau txais cov khoom siab tshaj -purity. Tag nrho cov txheej txheem tsim khoom yuav tsum nruj tswj qhov kub, siab, thiab cov khoom sib piv kom ntseeg tau tias kev ua haujlwm siab thiab kev txuag hluav taws xob.

Para xylene (1 4 dimethylbenzene) siv rau dab tsi?

Kev tsim khoom ntawm Terephthalic Acid (PTA)
Tshaj 99% ntawm lub ntiaj teb p-xylene yog siv los tsim PTA, cov khoom siv tseem ceeb rau:
