Abstract
In the presence of dodecylbenzene sulfonic acid (DBSA), a part of the phase diagram of water, oleic acid, and n-octanol was constructed as a function of the temperaure dependent from DBSA-concentration. The liquid three-phases microemulsion region in the phase diagram was efficient for the esterification of oleic acid and n-octanol. The results exhibit that the shift of phase boundary contributed to product separation and catalyst recycling.
Kurzfassung
In Gegenwart von Dodecylbenzensulfonsäure (DBSA) wurde das Teilphasendiagramm von Wasser, Ölsäure und n-Octanol als Funktion der Temperatur in Abhängigkeit von der DBSA-Menge konstruiert. Der Bereich der flüssigen Dreiphasen-Mikroemulsion im Phasendiagramm war für die Veresterung von Ölsäure und n-Octanol wirksam. Die Ergebnisse zeigen, dass die Verschiebung der Phasengrenze zur Produkttrennung und zur Katalysatorrückgewinnung beitrug.
