Abstract

Pseudo-ternary phase diagrams of 1-butyl-3-methylimidazolium hexafluorophosphate (bmimPF6) /Tween 80 (polyoxyethylene sorbitan monooleate)/alcohol/toluene systems were constructed with different linear-chain alcohols. The phase diagrams demonstrate that an increase in the surfactant/alcohol weight ratio yields a larger microemulsion domain. The different chain lengths of the alcohols affected the extent of the microemulsion region. Alcohols having short-chain lengths were optimum cosurfactants in bmimPF6-based microemulsion. Moreover, the influence on the microstructure of the single-phase area as a function of the alcohol chain was investigated using electrical conductivity. Preliminary investigations suggested that the bmimPF6-in-toluene region of systems which contain ethanol was notably magnified, and increasing in alcohol chain length (n = 4 – 10) led to a shrinkage for alcohols with longer chain length.

Kurzfassung

Es wurden pseudo-ternäre Phasendiagramme von Systemen aus 1-Butyl-3-methyl-imidazoliumhexafluorophosphat (bmimPF6) /Tween 80 (Polyoxyethylensorbitanmonooleate)/Alkohol/Toluen erstellt. Es wurden lineare Alkohole mit unterschiedlichen Alkylkettenlängen verwendet. Die Phasendiagramme zeigen, dass der Anstieg des Tensid-Alkohol-Verhältnisses zu einem größeren Mikroemulsionsbereich führt. Die unterschiedlichen Kettenlängen der Alkohole beeinflussen die Größe der Mikroemulsionsregion und Alkohole mit kurzen Ketten waren optimale Co-Tenside in der Mikroemulsion auf bmimPF6-Basis. Außerdem wurde der Einfluss auf die Mikrostruktur des Einphasenbereiches als Funktion der Alkoholkette mittels der elektrischen Leitfähigkeit untersucht. Vorhergehende Untersuchungen deuten darauf hin, dass die bmimPF6-in-Toluen-Region der Systeme, die Ethanol enthalten, deutlich vergrößert war und dass ein Anstieg der Alkoholkettenlänge (n = 4 – 10) zu einer Verkleinerung bei Alkoholen mit längerer Kettenlänge führte.
