Puas yog p-xylene (cas 106 42 3) zoo ib yam li xylene?
p-xylene (CAS 106-42-3)tsis zoo li xylene, tab sis nws yog ib qho ntawm peb isomers (ortho--xylene, meta-xylene, para-xylene).
p-Xylene (para-xylene) yog ib qho uas muaj ntxhiab hydrocarbon. Nws yog ib qho ntawm peb isomers ntawm dimethylbenzene hu ua xylenes. Lub p- sawv cev rau para-, qhia tias ob pawg methyl hauv p-xylene tuav cov diametrically opposite txoj hauj lwm 1 thiab 4. Nws yog nyob rau hauv txoj hauj lwm ntawm ob pawg methyl, lawv cov qauv hloov pauv, uas txawv ntawm lwm cov isomers, olen {{7} m-xylene. Txhua tus muaj tib yam tshuaj formula C6H4(CH3)2. Tag nrho cov xylene isomers yog cov xim tsis muaj xim thiab muaj cov nplaim taws heev. Cov ntxhiab tsw pib ntawm p-xylene yog 0.62 qhov chaw ib lab (ppm).
CAS Nr .: 106-42-3
Qauv:
qhov sib txawv ntawm xylene thiab p-xylene
| Feature | Xylene (Mixed Xylene) | p-Xylene (Para-Xylene) |
|---|---|---|
| Tshuaj Ntuj | Kev sib xyaw ntawm isomers (o-, m-, p-xylene) thiab feem ntau ethylbenzene. | Ib leeg, ntshiab tshuaj compound. |
