Kub Muag 99% CAS1330-20-7 Mixed Xylene
Xylene yog ib qho tseem ceeb petrochemical uas tsim nyob rau hauv kev tsim cov thee coking rau hauv coke roj los ntawm kev hloov kho catalytic. Nws ua li ntawm 0.5-1% ntawm cov roj crude thiab pom nyob rau hauv me me nyob rau hauv roj av thiab dav hlau roj. Cov khoom tseem ceeb ntawm kev rho tawm los ntawm kev hloov pauv catalytic hu ua "reformate", xylene yog ib feem ntawm BTX aromatics (xylene, benzene, thiab toluene). Cov sib tov yog ib tug me ntsis oily, tsis muaj kob kua uas yog siv raws li ib tug hnyav.
