Abstract:
The present invention relates to a method of producing terephthalic acid derivatives from isobutene via p-xylene. The isobutene is fermentatively produced isobutene, the higher purity of which improves the method and the properties of the produced p-xylene and the terephthalic acid derivatives derived therefrom.
