1. Salts of amino acids with alkylsulfonic acids form dimers in nonpolar solvents. In the case of α-amino acids, the carboxyl groups form a mutual H-bond, with NH3+ and SO3−. e-Amino acids associate just like carboxylic acids. 2. The OH groups of

1. In gas-liquid chromatography on a polar phase-1,2,3-tris-(2-cyanoethoxy)propane, in addition to the partitioning effect, there is adsorption at the gas-liquid and liquid-solid interfaces. Adsorption at the surface of the liquid phase occurs both f

1. The interaction of alkali metal ions with the SO 3 − group leads to a broadening of the bands of the valence vibrations of the latter and an increase in their frequencies. In dimethyl sulfoxide and water, this interaction is weakened. 2. Trisubs

1. During thermal (⩾ 230‡C) and p-toluenesulfonic acid-catalyzed (60–98‡C) cleavage of 4,4′-bis(1-acetoxyethyl)diphenyl ether, a mixture of 4-vinyl-4′-(1-acetoxyethyl)diphenyl and 4,4′-divinyldiphenyl ethers and the products of their ol

1. 1,2,3-Tris (2-cyanoethoxy)-propane is a selective phase for cis-trans. isomers of oxygen-containing compounds and hydrocarbons. 2. In many cases the separating efficiency of the column with the liquid phase studied increases with an increase in th
