Solubility of the following 1-alkanols (1-dodecanol, 1-tridecanol, 1-tetradecanol, 1-pentadecanol, 1-hexadecanol and 1-octadecanol) in dipropyl ether or dibutyl ether are reported, They have been measured by the dynamic method from a temperature close to 0 degrees C up to the melting point. All systems exhibit positive deviations from ideal solubility. For all the alcohols, two transition points close to the melting temperature have been observed, The abilities of the Modified UNIFAC (Dortmund) and the DISQUAC models to predict these data have been tested.
