Abstract
A number of binary systems have been studied, each involving a 1-monoglyceride. Included was the binary system of 1-monopalmitin (1P)-1-monostearin (1S). Other systems involved 2-monoglycerides, 1,3-diglycerides and triglycerides as follows: 2P-1P, 2S-1S, PP-1P, SS-1S, PPP-1P, SSS-1S. A general principle running through the observed behavior is that the more chemically similar the components, the greater is the interaction or solid solution formation. Thus 1P-1S showed continuous solid solution in both stable and metastable states with “compound formation” in the stable state. The systems 2P-1P and 2S-1S showed α (sub α) stability in a single solid solution phase for the range 20–80% 1-monoglyceride. The system PP-1P and SS-1S showed extensive solid solution formation in an α state but little or none in the stable state. There was essentially no solid solution formation observed for stable states of PPP-1P and SSS-1S; experimental limitations made it difficult to draw certain conclusions about the metastable state, but here, too, it is believed, solid solution formation was negligible.
