Abstract: A method for purifying a reclaimed polypropylene is disclosed. In one embodiment, the method involves obtaining reclaimed polypropylene, contacting the reclaimed polypropylene with a first fluid solvent to produce an extracted reclaimed polypropylene; then dissolving the extracted reclaimed polypropylene in a solvent to produce a first solution comprising polypropylene. The first solution is settled and then filtered. A purer polypropylene is separated from the resulting solution.

Abstract: 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.
