Abstract
Certain acidic heterogeneous catalysts produce large yields of benzene, toluene and xylene from alkyl aromatics of at least nine carbon atoms by a mechanism different from the classical disproportionation reaction characteristic of acid catalysts. Typically, aromatic mixtures so derived from such stocks have unusually low content of ethyl benzene, thus greatly simplifying separation of xylene isomers.
