Electrochemical Impedance Spectroscopy—A Simple Method for the Characterization of Polymer Inclusion Membranes Containing Aliquat 336
Electrochemical impedance spectroscopy (EIS) has been used to estimate the non-frequency dependent (static) dielectric constants of base polymers such as poly(vinyl chloride) (PVC), cellulose triacetate (CTA) and polystyrene (PS). Polymer inclusion membranes (PIMs) containing different amounts of PVC or CTA, along with the room temperature ionic liquid Aliquat 336 and plasticizers such as trisb...
متن کاملReactive Extraction of Propionic Acid with Aliquat 336 Dissolved in 1-Decanol and n-Dodecane
This paper deals with propionic acid extraction by Aliquat 336, a quaternary amine dissolved in ndodecane and 1-decanol. Chemical equilibrium experiments have been carried out to investigate the effect of modifier, 1-decanol on the extraction efficiency of Aliquat 336 in ndodecane at fixed initial acid concentration of 0.27 gmol/l. Extraction efficiency is determined in terms of distribution co...
متن کاملHeck reaction catalyzed by Pd/C, in a triphasic-organic/Aliquat 336/aqueous-solvent system.
The rate of the Pd/C catalyzed Heck coupling of Ar-I with CH(2)=CH-R is accelerated tenfold by the presence of Aliquat 336 (A336), a well known phase transfer catalyst, and an ionic liquid. Both when conducted in A336 as solvent, and in an isooctane/A336/aqueous triphasic mixture, the Heck reaction of aryl iodides with electron deficient olefins, catalyzed by Pd/C, proceeds with high yields and...
متن کاملKinetic Modeling of Chromium(iii) Extraction with Aliquat 336 from Alkaline Aqueous Solutions Containing Chlorides
The effects of time, composition and history of preparation of the aqueous phase on the liquidliquid extraction of chromium(III) with Aliquat 336 from the aqueous alkaline solutions containing chlorides were studied. At time far from the equilibrium the yield and initial rate of the chromium(III) extraction depend on NaOH concentration, ionic strength of the aqueous phase and the way of its pre...
متن کاملThe Effect of Surface Confined Gold Nanoparticles in Blocking the Extraction of Nitrate by PVC-Based Polymer Inclusion Membranes Containing Aliquat 336 as the Carrier
Clusters of gold nanoparticles (AuNPs) formed on the surface of PVC-based polymer inclusion membranes (PIMs) with a liquid phase containing Aliquat 336 as the carrier and in some cases 1-dodecanol or 2-nitrophenol octyl ether as plasticizers were found to inhibit the extraction of nitrate by the PIMs. This observation was based on gradually increasing the mass of AuNPs on the membrane surface a...
