| 제목 | A mult-fluid nonrandom lattice fluid theory for phase equilibria of (intra+inter) molecular associating systems |
| 초록 | Intramolecular associating bonds is an important contribution to the overall hydrogen bonding in amphipile systems, especially in systems of colloidal and biological interest. Glycol-ether compounds such as C1E1(2-methoxyethanol), C2E1(2-ethoxyethanol) and C4E1(2-butoxyethanol) form both intramolecular and intermolecular hydrogen bonds. This type of system (polyethoxyalcohols) is of direct interest on alkanol-alkane-ether systems as they involve the same type of interactions, and is of key importance in the study of non-ionic surfactants. The objective of this study is to present a multi-fluid nonrandom associating lattice model (MALF) for studying fluid systems with both intramolecular and intermolucular associating bonds in alkane + nonionic surfactant systems. Vapor liquid equilibria data for alkane + nonionic surfactant(C1E1, C2E1, C4E1) systems were correlated using intramolecular MALF equation of state. The MALF equation of state for both intramolecular and intermolecular hydrogen bonding for correlating parameters resulted in a better agreement with an experimental data than that for only intermolecular hydrogen bonding. |
