Abstract
Summary: A study of binary systems involving SSS with PPP, PSP, LLL, SOS, or OOO, also SOS with OOO shows, for these triglycerides, agreement of liquidus position with the Hildebrand solubility law. Solid solution is essentially absent in LLL‐SSS and OOO‐SSS and OOO‐SOS but definitely occurs with PPP‐SSS, PSP‐SOS, and SOS‐SSS, where it is clearly shown by x‐ray and dilatometric evidence. Solid solutions are particularly evident with metastable forms. Possibility of wide departure from equilibrium behavior is shown for “stabilized” samples in the SOS‐SSS case; low melting components melted out of solid solution below the system's complete melting point are able to reenter the solid solution phase only to a limited extent.Keywords
