Peculiar points of aqueous solutions of mono-hydrogen alcohols

[Display omitted] •The peculiar points in aqueous solutions of mono-hydrogen alcohols were study.•The solution at a peculiar point has a cellular structure formed by hydrate complexes or elementary clusters.•The volume and heat of dissolution per one cluster are determined.•The instability of elementary clusters near a peculiar point is considered. The work is devoted to the detailed study of the peculiar points in aqueous solutions of mono-hydrogen alcohols. The main attention is focused on water-methanol and water–ethanol solutions for which there are numerous experimental data. It is taken into account that H-bond interaction between alcohol and water molecules stimulates the formation of hydration complexes or elementary clusters, stable for temperatures: T
