PRODUCTION OF TEREPHTHALIC ACID VIA REDUCTIVE COUPLING OF PROPIOLIC ACID OR PROPIOLIC ACID DERIVATIVES

A method of making terephthalic acid via reductive coupling of two molecules of propiolic acid or propiolic acid derivatives is presented. The reductive coupling can be catalyzed by compounds comprising metals, and propiolic acid or propiolic acid derivatives can be produced from acetylene and carbo...

Summary:A method of making terephthalic acid via reductive coupling of two molecules of propiolic acid or propiolic acid derivatives is presented. The reductive coupling can be catalyzed by compounds comprising metals, and propiolic acid or propiolic acid derivatives can be produced from acetylene and carbon dioxide. At least 4 of the 8 carbons in the terephthalic acid are non-fossil-derived.
