In order to clarify the effect of molecular structure on states and properties of mixed monolayers, surface pressure-area(π-<I>A</I>) curves of the two-component surface films of long normal chain fatty acids with hexadecyl acetate were measured at various compositions and temperatures. By use of thermodynamic analysis, the phase diagrams and partial molar enthalpy changes were calculated. For four systems studied in the present paper it was found that the diagram and enthalpy change vary characteristically with the number of carbon atoms of acids, but the dependence on the chain length of acid in fatty acid–hexadecyl acetate systems was very different from that in fatty acid–ethyl hexadecanoate systems.
