Abstract

The effects of oil-water ratios (α) on the composition of the balanced interfacial layer and the optimum solubilization of microemulsions C16mimBr/butan-1-ol/oil (octane, decane, dodecane)/5% NaCl solution were investigated. As α increases, the alcohol solubility in water and oil phases (Sa) in the microemulsions also tends to increase. The reason is the relatively high solubility of the alcohol in the oil phase compared to the solubility in water. When α increases, the number of surfactant (nss) and co-surfactant (nas) molecules required to balance the interface layer and the proportion of alcohol in the interfacial layer (AS) increase but the solubilization capacity (SP*) decreases. When the total mass of water and oil is unchanged, the solubilization capacity of the microemulsion systems is lower the higher the relative content of oil is. The effects of different oils, salinity and temperature on the composition of the balanced interfacial layer and the solubilization of microemulsions were also investigated.

Kurzfassung

Die Einflüsse des Öl-Wasser-Verhältnisses (α) auf die Zusammensetzung der Grenzflächenschicht im Gleichgewicht und die optimale Solubilisierung der Mikroemulsionen C16mimBr/Butan-1-ol/Öl (Oktan, Dekan, Dodekan)/5 % NaCl-Lösung wurden untersucht. Mit zunehmendem α, nimmt auch die Alkohollöslichkeit in der Wasser- und Ölphase (Sa) in den Mikroemulsionen zu. Der Grund dafür ist die im Vergleich zur Löslichkeit in Wasser relativ hohe Löslichkeit des Alkohols in der Ölphase. Wenn α zunimmt, nimmt die Anzahl der Tensid (nss)- und Co-Tensid (nas)-Moleküle, die erforderlich sind, um die Grenzschicht und den Alkoholanteil in der Grenzschicht (AS) ins Gleichgewicht zu setzen, zu und die Solubilisierungskapazität (SP*) ab. Bei unveränderter Gesamtmasse von Wasser und Öl ist die Solubilisierungskapazität der Mikroemulsionssysteme niedriger, je höher der relative Gehalt an Öl ist. Die Wirkungen verschiedener Öle, des Salzgehalts und der Temperatur auf die Zusammensetzung der Gleichgewichtsgrenzflächen und die Solubilisierung von Mikroemulsionen wurden ebenfalls untersucht.
