Qhov txawv ntawm xylene thiab p-Xylene yog dab tsi?

Xylene yog ib qho organic compound. Nws yog ib qho ntawm peb isomers ntawm dimethylbenzene. Nws muaj ob pawg methyl txuas rau lub nplhaib benzene ntawm ntau txoj haujlwm. Cov tshuaj formula ntawm xylene yog (CH₃)₂C₆H₄. Peb lub isomers ntawm dimethylbenzene yog ortho-xylene,para-xylene (CAS 106-42-3)thiab meta-xylene.

Qhov txawv ntawm xylene thiab p-Xylene yog dab tsi?

Xylene yog ib qho sib xyaw ntawm peb tus qauv isomers.

• p-Xylene (para-xylene, CAS 106-42-3): Ob pawg methyl nyob ntawm 1,4-txoj hauj lwm (piv txwv li ntawm lub nplhaib benzene).
• o-Xylene (ortho-xylene, CAS 95-47-6): Ob pawg methyl nyob ntawm 1,2-txoj hauj lwm (nyob ib sab).
• m-Xylene (meta-xylene, CAS 108-38-3): Ob pawg methyl nyob ntawm 1,3-txoj hauj lwm (sib cais los ntawm ib tug carbon atom).

Daim ntawv thov

Xylene (mixed isomers):

Feem ntau yog siv los ua ib qho dav dav -lub hom phiaj organic hnyav hauv kev lag luam xws li txheej, luam ntawv, roj hmab, thiab ntxuav hlau. Nws kuj yog ib qho tshuaj reagent nyob rau hauv chav kuaj ua qauv npaj.

p-Xylene:

Cov isomer tseem ceeb tshaj plaws hauv tsev neeg xylene, tshwj xeeb rau kev tsim cov ntaub ntawv polyester. Para Xylene P-Xylene yog oxidized rau terephthalic acid (TPA), uas yog cov khoom siv tseem ceeb rau polyethylene terephthalate (PET) - cov khoom siv rau lub raj mis yas, polyester fibers, thiab cov khoom ntim zaj duab xis.
