Daim ntawv thov:
Kev siv loj tshaj plaws ntawm meta-xylene yog nyob rau hauv kev tsim cov isophthalic acid, uas yog siv los ua copolymer los hloov cov khoom ntawm polyethylene terephthalate. Kev hloov pauv ntawm meta-xylene rau isophthalic acid yuav tsum tau catalytic oxidation. Meta-xylene kuj tseem siv rau hauv kev tsim khoom ntawm 2,4- thiab 2,6-xylidine, nrog rau ntau yam tshuaj me me. [8] [6] Amoxidation ntawm meta-xylene tsim isophthalonitrile.
