METHODS FOR PRODUCTION OF TEREPHTHALIC ACID FROM ETHYLENE OXIDE

The present invention provides methods for the production of terephthalic acid and derivatives thereof using ethylene oxide, carbon monoxide and furan as feedstocks. The process is characterized by high yields and high carbon efficiency. The process can utilize 100% biobased feedstocks (EO via ethanol, CO via biomass gasification, and furan via known processes from cellulosic feedstocks).

Noncovalent catch and release of carboxylates in water

Association constants of a bis-(acetylguanidinium)ferrocene dication to various (di)carboxylates were determined through UV-vis titrations. Association constant values greater than 104 M-1 were determined for both phthalate and maleate carboxylates to the bis-(acetylguanidinium)ferrocene salt in pure water. Density functional theory computations of the binding enthalpy of the rigid carboxylates for these complexes agree well with the experimentally determined association constants. Catch and release competitive binding experiments were done by NMR for the cation-carboxylate ion-pair complexes with cucurbit[7]uril, and they show dissociation of the ion-pair complex upon addition of cucurbit[7]uril and release of the free (di)carboxylate.
