The distribution of normal alcohol (n-alcohol) on water and the stability of the alcohol distribution were investigated using molecular dynamics simulation for three types of 72-alcohol (n-propanol, C_3H_7OH ; n-heptanol. C_7H_<15>OH ; and n-undecanol, C_<11>H_<23>OH), four of five concentrations of alcohol. The simulation results reveal the following. The distribution of n-propanol on water is homogeneous at all n-alcohol concentrations studied here and the distribution of n-heptanol and n-undecanol on water is heterogeneous. The n-alcohol concentration at which fluctuations in the alcohol distribution begin to increase depends on the length of the hydrocarbon chain of the n-alcohol.
