Abstract
Vapor pressure determinations in a vacuum line were made first on varied compositions of acetone and pyridine and second on varied compositions of acetone and trimethylamine. These experiments were conducted in the hope of noting a negative deviation from Raoult's Law, which is indicative of adduct formation between the two substances. No such deviation was found in either case. Vapor pressure determinations were then made on varied compositions of 1) acetone and chloroform, 2) 4-heptanone and chloroform, 3) dicyclopropyl ketone and chloroform, and 4) diisopropyl ketone and chloroform. In each of these systems a negative deviation from Raoult's Law was found, and from these data values for the relative electronegatities of the propyl groups were obtained.
