Pervaporation separation of ethyl butyrate and isopropanol with polyether block amide (PEBA) membranes

Silicalite‐Filled PEBA Membranes for Recovering Ethanol from Aqueous Solution by Pervaporation

“…Böddeker et al [8] found that PEBA40 membranes have a better permeability than other elastomeric membranes (e.g., silicone-based membranes) in the separation of butanol isomers and benzyl alcohol from water. The separation of a small amount of aroma compounds, such as n-butyl acetate, n-butanol, ethyl butyrate, and isopropanol from aqueous solutions, was studied using a PEBA membrane [9,10]. The potential of using PEBA membranes for acetone-butanol-ethanol (ABE) extraction from dilute aqueous solutions was also demonstrated by Liu et al [11] and Fouad and Feng [12].…”

“…Nomura et al [16] examined the transport phenomena of ethanol through intracrystalline and intercrystalline pathways of silicalite membranes separately, and an intercrystalline-intracrystal-line model was proposed. According to this model, ethanol was permselective from ethanol/water mixtures through intercrystalline pathways.…”

Fabrication of PEBA/Cu2O mixed-matrix membranes and their application in pyridine recovery from aqueous solution

“…PEBA membranes have been found to exhibit a considerably high affinity to aromatic compounds from water by pervaporation. 27,28 Furthermore, the preparation of PEBA-based membranes is very simple: dissolution-casting-evaporation without any cross-linking reaction, polymerization or stretching. These features are benecial for the industrial application of PEBA membranes.…”

Efficient recovery of high‐purity aniline from aqueous solutions using pervaporation‐fractional condensation system

“…The hard PA segments provide good mechanical strength, while the soft PE segments offer a better permselectivity. 30,31 PEBA was found to have exceptional selectivity for the separation of aromatic hydrocarbons from water by pervaporation. 32 The good selectivity of PEBA to aromatic compounds permeation derives from the strong affinity between the PE segments and aromatic compounds.…”
