The solubilities of 1-hexanol, 1-octanol, 1-decanol, and 1-dodecanol in 1-propanol-water mixtures were measured. Solubility increased with rise in temperature and increasing concentration of 1-propanol. The slope of a plot of -1n (solubility) against 1/T became large as the 1-propanol concentration decreased. The dependence of solubility on the 1-propanol concentration increased in proportion to solute size.
