Phase behavior of mixed systems of SOS and OSO

Abstract: Iyoda, T.; Ohtani, A,; Shimidzu, T.; Honda, K. Chem. L r r . 1986,687. (c) Yoneyama, H.; Hirai, T.; Kuwabata, S.; Ikcda, 0. Chem. Leu. 1986,1243. (d) Shimidzu, T.; Ohtani, A.; Iyoda, T.; Honda, K.The phase behavior of mixed systems of SOS (sn-1,3-distearoyl-sn-2-oleoylglycerol) and OS0 (sn-1.3-dioleoyl-sn-2stearoylglycerol) was studied with X-ray diffractometry and thermal analysis by using pure samples (>98.0%). A molecular compound was formed at the mixture of equal weight ratio, giving rise to two monotecti… Show more

“…In all the mixtures, the compound formation was observed at the 1:1 (w/w) concentration ratio, indicating specific molecular interactions through the acyl chain moieties. It is worth noting that oleoyl chains are commonly present in all the component TAG of the mixture systems as saturated-oleoyl mixed acid TAG (15)(16)(17).From a technological implication, the occurrence of crystallization and transformation of TAG in the metastable forms is the important process leading to the growth of hard and brittle crystals. Therefore, it is interesting to elucidate the molecular structures and kinetic properties of the mixture systems.…”

“…The formation of a molecular compound may be viewed as a special case of eutectic mixing systems that occurs as a result of specific molecular interactions between the component TAGs. Two examples are shown in Table 1.3: for an SOS/OSO mixture (Koyano et al, 1992) and for a POP/PPO mixture …”

“…For simplicity, multiple β and β forms (β 2 , β 1 , β 2 , β 1 ) are represented by β and β. Polymorphic forms with double or triple chain-length structure are presented as α-2, γ-3, β -2. a P: palmitoyl, S: stearoyl, O: oleoyl, R: ricinoleoyl, L: linoleoyl, E: elaidoyl (data based on previous research) 1,[13][14][15][16][17][18][19][20][21][22][23][24][25] arate leaflets, with stabilized aliphatic chain-chain interactions. With regard to POP/OOP, in case 1, it causes destabilization due to the coexistence of oleoyl and palmitoyl chains in both the leaflets.…”

“…1 a and b . In each mixture, the MC was formed at a concentration ratio of 1:1 13,14 . The most stable form of MC was the β form, The formation of MCs was also observed in some binary mixtures between symmetric and asymmetric saturatedoleic diacid TAGs, such as SOS/SSO 15 and POP/PPO 16 SSO: 1,2-distearoyl-3-oleoyl-rac-glycerol; PPO: 1,2-dipalmitoyl-3-oleoyl-rac-glycerol .…”
