“…where 𝑥 𝑝 is the concentration of the aqueous solution at the special point of the corresponding alcohol. The further analysis of the concentration behavior of the clustering degree of alcohols is performed according to the density of their aqueous solutions: methanol [31], ethanol [32], 1-propanol [33], and 1-butanol [34], depending on the normalized concentration (see Fig. 1).…”

“…4) 1-butanol. The solution densities were taken from [31] for methanol, [32] for ethanol, [33] for 1-propanol, and [34] for 1-butanol. The concentration is determined by formula (11) The exclusive position of 1-butanol solutions (see Fig.…”
