Abstract
![]()
Wide-angle X-ray
scattering patterns were recorded for a series
of aliphatic butanol isomers (n-, iso-, sec-, tert-butanol) and their
phenyl derivatives (4-phenyl-1-butanol, 2-methyl-3-phenyl-1-propanol,
4-phenyl-2-butanol, and 2-methyl-1-phenyl-2-propanol, respectively)
to determine their atomic-scale structure with particular emphasis
on the formation of supramolecular clusters. In addition, molecular
dynamics simulations were carried out and yielded good agreement with
experimental data. The combination of experimental and theoretical
results allowed clarification of the origin of the pre-peak appearing
at low scattering angles for the aliphatic butanols and its absence
for their phenyl counterparts. It was demonstrated that the location
of the hydroxyl group in the molecule of alkyl butanol, its geometry,
and rigidity determine the morphology of the supramolecular clusters,
while the addition of the aromatic moiety causes more disordered organization
of molecules. The phenyl group significantly decreases the number
of hydrogen bonds and size of the supramolecular clusters formed via
the O–H···O scheme. The lower association ability
of phenyl alcohols via H-bonds is additionally attenuated by the appearance
of competing π–π configurations evidenced by the
structural models.

Abstract
Despite butanol isomers such as n-butanol, sec-butanol, isobutanol and tert-butanol having the same chemical formula, their liquid-liquid phase diagrams are distinct. That is, tert-butanol is miscible in water at all concentrations, while the other three butanol isomers are partially miscible under ambient conditions. The molecular shape of tert-butanol is close to globular and differs from the other three butanol molecules with a relatively long carbon chain. By performing molecular dynamics simulations and graph theoretical analysis of the four water-butanol isomer mixtures at varying concentrations, we show how distinct butanol aggregates are formed which depend upon the molecular shape and affect the water H-bond network structure and phase diagram in the binary liquid. The three butanol isomers of n-butanol, sec-butanol and isobutanol at concentrated solutions form chain-like alcohol aggregates, but tert-butanol forms small aggregates due to the distinct packing behavior caused by its globular molecular shape. By employing the graph theoretical analysis such as the degree distribution and the eigenvalue spectrum from the adjacency matrix in the graphical representation of the alcohol H-bond network, we show that the tert-butanol aggregates have a different morphological structure from that of the other three butanol isomers in aqueous solution. The graph theoretically distinct butanol aggregates are categorized into two groups, water-compatible and water-incompatible, depending upon the interaction between the alcohol and water molecules. Based upon our observations, we propose that the water-incompatible networks of n-butanol, sec-butanol and isobutanol aggregates do not change the water structure significantly, forming two separate liquid phases that are alcohol-rich and water-rich. However, the water-compatible network of tert-butanol aggregates has a considerable interaction with the water molecules and causes significant disruption of the water H-bond network, forming a homogeneous solution. Understanding the alcohol aggregation behavior and water structure in butanol-water mixtures provides a critical clue in appreciating fundamental issues such as miscibility and phase separation in aqueous solution systems.
