英文摘要: Abstract(#br)Membrane pervaporation has gained much attraction for high level purity of acetic acid from water because of energy saving and ecofriendly operation compared with distillation and extraction. However, fabricating membranes with high stability, selectivity and permeation flux for dehydration of acetic acid by pervaporation is highly demanded. In this work, hybrid silica membranes were fabricated using bis(triethoxysilyl) ethane (BTESE) as a precursor through sol gel route. Further modification was done as solid post HCl treatment for the synthesized BTESE membrane aiming to improve separation performance of the BTESE membranes for dehydration of acetic acid. The effect of HCl exposure time (30, 100, and 150 min) to the synthesized BTESE membranes was investigated to get...
