C9 Aromatics

c9 main means of restructuring and catalytic cracker ethylene-containing by-product of the nine carbon atoms aromatic

Cumene is the main component, is C benzene, ethyl toluene and 1,3,5-side with three toluene, o 3 toluene, such as indinavir. 9 aromatic carbon restructuring aromatics about 80% to 90%, with three of 50% toluene, methyl benzene B 20% to 25%. The pyrolysis gasoline aromatics, nine aromatic carbon 20%, of which three toluene 4% to 6%. C9 aromatics complex distillate component, similar to the boiling point, the separation is difficult to January 1, mainly isolated partial three toluene and 1,3,5 system for trimellitic anhydride and Pyromellific anhydride, used in the coatings, such as synthetic resin. Carbon 9 aromatic fractions can be used directly in the oil resin system, the general fuel use.
