Sol-gel encaged [(C8H17)3NCH3][RhCl4] catalyses the double bond isomerization in the flavoring agent 4-allylanisole in aqueous microemulsions. In order to provide optimal composition of the reaction medium water/n-propanol/surfactant/4-allylanisole micellar systems were formulated. The surfactants were sodium dodecyl sulfate, cetyltrimethylammonium bromide, sucrose monolaurate, and polyethylene glycol (7) glyceryl cocoate. The ratio (w/w) of n-propanol/surfactant equals 2/1. The extent of the microemulsions region as function of temperature was determined. The micellar systems were characterized by the volumetric parameters, density, excess volume, ultrasonic velocity and isentropic compressibility. The micellar densities increase with the increase in the water volume fraction. Ultrasonic velocities increase with the increase in water volume fraction up to 0.8 then decrease. Ultrasonic velocities increase with temperature for water volume fractions below 0.8 and decrease for water volume fractions above 0.8. Quantitative analysis of the volumetric parameters enabled the characterization of structural transition along the micellar phase. The particle hydrodynamic diameter of the oil-in-water systems was determined as function of temperature. The particle hydrodynamic diameter decreases in the case of the ionic surfactants while in the case of nonionic surfactants it increases.


Das in einem Sol-Gel eingeschlossene [(C8H17)3NCH3][RhCl4] katalysiert die Isomerisierungsreaktion an den Doppelbindungen des Aromastoffs 4-Allylanisol in wässrigen Mikroemulsionen. Mit dem Ziel, die optimale Zusammensetzung des Reaktionsmediums zu finden, wurden mizellare Systeme aus Wasser/n-Propanol/Tensid/4-Allylanisol formuliert. Bei den verwendeten Tensiden handelt es sich um Natriumdodecylsulfat, Cetyltrimethylammoniumbromid, Saccharosemonolaurat, und Polyethylenglykol-(7)glycerylcocoat. Das Verhältmis (w/w) von n-Propanol zu Tensid betrug 2:1. Die Größe des Mikroemulsionsbereiches wurde als Funktion der Temperatur bestimmt. Die mizellaren Systeme wurden anhand volumetrischer Parameter, der Dichte, des Überschussvolumens, der Ultraschallgeschwindigkeit und der adiabatischen Kompressibilität charakterisiert. Die mizellaren Dichten nehmen mit steigendem Volumenanteil des Wassers zu. Die Ultraschallgeschwindigkeiten steigen mit zunehmenden Volumenanteilen des Wassers an bis der Volumenanteil 0,8 beträgt, dann sinken die Ultraschallgeschwindigkeiten. Für Volumenanteile unterhalb von 0.8 steigen die Ultraschallgeschwindigkeiten mit der Temperatur und fallen bei Volumenanteilen von Wasser größer als 0,8. Mittels der quantitativen Analyse der volumetrischen Parameter konnte der Strukturübergang entlang der mizellaren Phase charakterisiert werden. Der hydrodynamische Partikeldurchmesser der Öl-in-Wasser-Systeme wurde als Funktion der Temperatur bestimmt. Der hydrodynamische Partikeldurchmesser nimmt bei Verwendung von ionischen Tensiden ab und bei Verwendung nichtionischer Tenside zu.
