o-Xylene (CAS 95-47-6) yog dab tsi?
Phthalic anhydride (C8H4O3) yog tsim los ntawm catalytic vapor-theem oxidation ntawmo-xylene (CAS 95-47-6)(C8H10) nrog cua, nqa tawm nyob rau hauv ib tug ruaj - txaj, multi-tubular reactor. Cov txheej txheem siv lub catalyst muaj xws li vanadium pentoxide (V2O5) thiab titanium dioxide (TiO2), ua haujlwm ntawm qhov kub ntawm 340-450 degree. Cov tshuaj tiv thaiv tseem ceeb yog:
C8H10+3O2→C8H4O3+3H2O
