Vapor permeation (VP) of water (H2O)/ acetic acid (AcOH) mixtures via bis(triethoxysily)ethane (BTESE) membranes
Bis(triethoxysilyl)ethane (BTESE)-derived organosilica membranes prepared using sol-gel processing, were used in vapor permeation (VP) to dehydrate aqueous acetic acid (AcOH) solutions. It was discovered that BTESE-derived membranes had outstanding stability and great permselectivity. BTESE-derived organosilica membranes showed a H2O/AcOH separation factor of 3000–5800 and a H2O/AcOH permeance ratio of 3000–5800 with the permeate flux of 12–28 kg m−2 h−1 for H2O/AcOH mixtures (AcOH: 50 wt%) under 120 °C and 100 kPaA. The superior durability of organosilica membranes was confirmed by long-term stability tests conducted in aqueous AcOH mixtures, which indicates that BTESE membranes maintained almost the stable flux and separation factors. A comparison with gas permeation properties indicates that the molecular sieving effect dominates the separation mechanism.
