Puas yog para-xylene (p xylene) soluble hauv dej?
Para-Xylene (P-Xylene)yog insoluble hauv dej tab sis miscible nrog ethanol, diethyl ether, chloroform, acetone, benzene, thiab feem ntau lwm cov organic solvents.
P-Xylene feem ntau yog siv los ua cov khoom siv los ua cov polyester fibers, resins, coatings, dyes, thiab tshuaj tua kab. Nws kuj ua hauj lwm raws li tus qauv tshuaj thiab hnyav rau chromatographic tsom xam thiab yog ua hauj lwm nyob rau hauv cov organic synthesis.
Cov khoom ntawm Para-Xylene (P-Xylene)
Para-Xylene (PX) yog cov kua tsis muaj xim, pob tshab nrog cov ntxhiab tsw ntxhiab, cais ua cov tshuaj tsw qab hydrocarbon. Nws cov qauv tshuaj yog C8H10, muaj ob pawg methyl thiab lub nplhaib benzene hauv nws cov qauv molecular. PX nthuav tawm cov ntsiab lus siab melting thiab boiling ntawm 13.2℃thiab 138.4 degree, feem. Nws yog insoluble hauv dej tab sis soluble hauv organic solvents.
Kev tsim cov txheej txheem ntawm Para-Xylene (P-Xylene)
Muaj ob txoj hauv kev tseem ceeb rau kev tsim Para-Xylene: ib qho yuav tsim cov tshuaj tsw qab los ntawm kev hloov pauv catalytic ntawm naphtha, ua raws li kev sib cais P-Xylene los ntawm cov khoom sib xyaw; lwm tus tsim P-Xylene los ntawm cov tshuaj tiv thaiv tsis sib xws ntawm toluene. Tam sim no, cov txheej txheem naphtha catalytic hloov kho yog txoj hauv kev ntau lawm. Txawm li cas los xij, vim muaj qee qhov chaw ntawm naphtha feedstock thiab kev siv lub zog siab thaum lub sij hawm tsim khoom, txoj kev toluene disproportionation tau txais kev saib xyuas.
