ABSTRACT

The solubilities of the fatty acids, tetradecanoic (myristic), hexadecanoic (palmitic), and octadecanoic (stearic), and of the triglycerides, glyceryl tridodecanoate (trilaurate), glyceryl trimyristate, glyceryl tripalmitate, and glyceryl tristearate, in 1-bromopropane were measured by the dynamic method from (280 to 350) K. The solubility of fatty acids decreased with the increase of molecular weight and was lower than ideal solubility. The systems triglycerides-1-bromopropane presented negative deviations of Raoult's law. The experimental data were correlated with Van Laar, Wilson, nonrandom two-liquid (NRTL), and universal quasichemical activity coefficient (UNIQUAC) equations.
