THE ASSOCIATION OF i-BUTYRATE AND TRIMETHYLACETATE IONS IN WATER

The electric conductivities of sodium i-butyrate and trimethylacetate were measured in water at 25°C. It was shown that the molar conductivities of both solutions reach a maximum at a concentration of about 1 mol m−3 (McBain effect), and that the hydrophobic interaction of i-butyrate and trimethylacetate ions is so strong that these ions form a dimer.
