Thermodynamics of aqueous potassium carbonate, piperazine, and carbon dioxide
TL;DR: In this paper, a thermodynamic model based on the electrolyte nonrandom two-liquid (ENRTL) theory was developed to describe the equilibrium behavior of the solvent, and it was shown that the carbamate stability of piperazine and PZ resembles primary amines and gave approximately equal values for the heats of reaction, ΔHrxn (18.3 and 16.5 kJ/mol).

Ju Weon Lee,Zoltán Horváth,Alexander G. O'Brien,Peter H. Seeberger,Peter H. Seeberger,Andreas Seidel-Morgenstern,Andreas Seidel-Morgenstern +6 more
TL;DR: In this article, a conceptual framework for analyzing and designing the coupling of flow synthesis and simulated moving bed (SMB) chromatography exploiting an integrated and continuously operated system was presented. And the reaction kinetics and the retention behavior in the chromatographic column were quantified in preliminary runs.

Structural Dynamics and Charge Transfer in Electronically Excited N,N′-Dimethylpiperazine
TL;DR: In this paper, the authors explore how the transfer of a (partial) charge is linked to the structural deformations of the molecular skeleton, showing that upon excitation to the 3p Rydberg level at 207 nm, only one of the initially symmetry-equivalent nitrogen atoms acquires the charge, creating an asymmetric molecular structure with a localized charge.
