Notes:
Proton magnetic resonance dilution studies of acetone phenylhydrazone were carried out in n-heptane, carbon disulphide and hexachlorobutadiene solutions. Equilibrium constants and enthalpy values for the predominant self-associated species are reported. Linear trimeric aggregates predominate in n-heptane solutions. The monomeric units are associated by intermolecular hydrogen bonding of the NH proton to the iminic nitrogen. The enthalpy per hydrogen bond is 10.04 kJ (2.4 kcal). In carbon disulphide and hexachlorobutadiene solutions complexation of acetone phenylhydrazone with the solvent competes with self-association.
