The deprotonation kinetics of the DEA--C02 and the DIPA-COZ zwitterions have been studied in aqueous blends of an&es at 298 K. Amine mixtures investigated were: DEA-TEA, DEA-MDEA. DEL-DMMEA, DEA-DEMEA, DIPA-TEA, DIPA-MDEA, DIPA-DMME~ DIPA-DEMEA. FOG each blend the zwitterion deprotonation constant of the additonal base present in solution (i.e. the tertiary amine) was determined. The observed d...

We present a new family of metal based ionic liquids (MetILs) for use in flow battery applications. These materials are synthesized in a single step by simply heating a metal salt in the presence of a ligand containing multiple polarizable functional groups. The utility of this reaction has allowed a wide range of metal cation, anion and ligand combinations to be prepared and electrochemically ...

The densities of aqueous mixtures of aminoethylethanolamine (CAS #000111-41-1) were measured over the entire compositional range at temperatures of 283.15-343.15 K. The results of these measurements were used to calculate excess molar volumes and isobaric thermal expansion coefficients, and partial molar and apparent molar volumes and excess isobaric thermal expansion coefficients were subseque...

Pyrolysis of waste tyres produces harmful hydrogen sulfide and other mercaptan compounds as by-products. The current study is concerned with the purification hydrogen-rich pyrolysis gas from that present in a great amount (up to 5.1% mol at 420 °C), mercaptans are also problematic impurities. method proposed absorption by alkanolamines which one most economical methods applied natural sweetenin...
