摘要
The aggregation of some aldehydes in nonpolar solvents was investigated using the static dielectric method. The molecular association of acetone and two of its derivatives ( acetophenone and benzophenone) in cyclohexane solvent were also investigated by this method. Analysis of the static dielectric data for solution of these materials indicated a high molecular association. It was found that benzaldehyde and its derivatives have a strong tendency for antiparallel molecular association, whereas acetone and its derivatives have a tendency for parallel alignment. The experimental results show that there is a sensitive relationship between the molecular association and molecular structure of these materials. The influence of solvent on the molecular association of the solute molecules was studied and compared.
