Abstract (en)

[origin: WO2014005846A1] The invention relates to a method for producing terephthalic acid derivatives from isobutene via p-xylene. The isobutene used is enzymatically produced isobutene, the higher purity of which improves the method and the properties of the produced p-xylene and of the terephthalic acid derivatives derived therefrom.
