The Effect of Concentrated Salt Solutions on the Activity Coefficient of Acetyltetraglycine Ethyl Ester

“…Refractive index measurements on solutions of simple amides and such aromatic compounds as phenol, in water and other solvents, have suggested the existence of a 1:1 complex of the two solutes. 60 The nuclear magnetic resonance and infrared spectra of N-methylamides in nonaqueous solvents show changes in the presence of aromatic compounds which have been interpreted as evidence for complex formation.61 Neutral as well as anionic aromatic molecules bind to polyvinylpyrrolidone, and it has been suggested that the thermodynamic parameters of this binding indicate an exothermic interaction of the -electron systems of the aromatic and amide groups, in addition to hydrophobic binding in this system.470 Nylon and wool show a strong adsorption of phenol from aqueous solution and an adsorption of benzene from butanol solution, which suggests the existence of an interaction between the aromatic ring and the amide groups of the polymer, although hydrogen bonding may also be involved in the binding of phenol.62…”

Acid-Base Titrations in Nonaqueous Solvents

“…Jander and Kraffczyk (103) postulate ionic reactions for lithium hydride as a titrant in ethyl ether (see also 102). Conductometric titrations of the following in ethyl ether solutions with lithium aluminum hydride show inflections at the mole ratios indicated: acetone 4 to 1, ethyl acetate 2 to 1, acetonitrile 2 to 1, acetamide 2 to 1, nitrobenzene 1 to 1, silver perchlorate 1 to 1, zinc iodide 4 to 1 and 2 to l, gallium bromide 1 to 1, 2 to 1, and 3 to 1.…”
