The influence of bromide-based ionic liquids on solubility of {LiBr (1) + water (2)} system. Experimental (solid + liquid) phase equilibrium data. Part 2
(3)} ternary systems, with fixed IL to LiBr mass fraction w = 0.3 for all ILs and w = 0.1 and 0.2 for ammonium-based ILs and [MOR1,3SO3] have been performed by dynamic method. For all of the tested systems the transition point betweenlithium bromide dihydrate and monohydrate form was observed. Significant solubility enhancement of lithium bromide in water was obtained by adding ionic liquid, or zwitterionic

We present deuteronquadrupolecouplingconstants (DQCC) for hydroxyl-functionalized ionic liquids (ILs) in the crystalline or glassy states characterizing two types of hydrogen bonding: The regular Coulomb-enhanced hydrogen bonds between cation and anion (c-a), and the unusual hydrogen bonds between cation and cation (c-c), which are present despite repulsive Coulomb forces. We measure these sensitive

human diseases. In a pilot study, novel muscarinic antagonists were synthesized and used as chemicalprobes to obtain additional information of the muscarinic pharmacophore. The design of these ligands made use of current orthosteric and allosteric models of drug–receptor interactions together with chemical motifs known to achieve muscarinic receptor selectivity. This approach has led to the discovery
