Abstract
Official abstract text for this publication.
A process is described for making renewable para-xylene, comprising converting acetic acid to isobutene in the presence of a catalyst then converting the acetic acid-derived isobutene to a product composition including para-xylene. The catalyst can be a Zn x Zr y O z mixed oxide catalyst.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for making para-xylene, comprising converting acetic acid to isobutene in the presence of a mixed oxide catalyst comprising a formula of Zn x Zr y O z , wherein the ratio of x:y is from 1:100 to 10:1 and z is a stoichiometric integer for the mixed oxide catalyst, then converting the isobutene to a product composition including para-xylene. 2. The process according to claim 1 , wherein the conversion of the isobutene to the parax…
