Effect of Trace Impurities on a Bifurcation Structure in the Belousov-Zhabotinski Reaction and Preparation of High-Purity Malonic Acid

We have found that impurities on the ppm level in malonic acid are sufficient to alter dramatically a sequence of bifurcations in the Belousov-Zhabotinskii (BZ) reaction.Samples of malonic acid from 15 vendors were tested, and each was found to contain one or more of the following impurities that effect the reaction dynamics: iron, paraformaldehyde, ethanol, methanol, ethyl ester, and methyl ester.We describe a straightforward procedure for purifying malonic acid.Reproducible bifurcation structures can only be observed with the highly purified malonic acid.Measurements with varying amounts of the above-mentioned impurities added to purified malonic acid show the striking effect of impurities on the dynamics of the BZ reaction.

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.
