Abstract
Various phenomena of binary systems of (S) - (SSS), (S) - (PPP), (S) - (MMM) and (S) - (OOO) were examined by differential scanning colorimetry (DSC).
1) Endothermic and exothermic peaks obtained by measurement of the metastable and stable states of the binary systems by DSC were assignable to respective endothermic and exothermic peaks of the single component constituting the binary systems. Consequently, phase diagrams of the metastable and stable states can be prepared easily from DSC.
2) Metastable and stable states in the phase diagrams of these binary systems did not show solid solution. Consequently, these binary systems do not form solid solutions in the solid state and the modification points of the two components appear at different temperatures in the phase diagram. Similar phase diagrams were obtained for all these binary systems.
3) The two components constituting the system undergo transition separately, although the transition rate is strongly affected by the second component. Transition rate of (S) in the binary systems is markedly suppressed by (SSS) and (PPP), but accelerated by (MMM) and (OOO). On the other hand, the triglycerides in the binary systems are affected by (S), the transition rate of (SSS) becoming slower and that of (PPP) and (MMM) tending to become faster.
