Qhov txawv ntawm p-Xylene thiab o-Xylene yog dab tsi?
1. Cov qauv sib txawv
p-Xylene thiab o-xylene yog ob qho tib si isomers ntawm dimethylbenzene, nrog rau cov tshuaj formula C₈H₁₀. Lawv lub ntsiab sib txawv nyob rau hauv txoj hauj lwm ntawm ob pawg methyl txuas rau lub nplhaib benzene.
Rau o-xylene (1,2-dimethylbenzene), ob pawg methyl nyob rau ntawm cov pa roj carbon atoms ntawm lub nplhaib benzene.
Rau p-xylene (1,4-dimethylbenzene), ob pawg methyl nyob rau ntawm cov pa roj carbon atoms ntawm lub nplhaib benzene.

3. Qhov sib txawv ntawm daim ntawv thov
p-Xylene feem ntau yog siv los ua terephthalic acid, uas yog ib qho tseem ceeb rau PET lub raj mis yas thiab polyester fibers.
O-xylene feem ntau yog siv rau hauv kev tsim phthalic anhydride, thiab nws yog tsim thaum roj av tawg.
