제목 Silicon-polyvinyl alcohol hybrid pervaporation membrane for dehydration of ternary mixtures comprising highly reactive epichlorohydrin
초록 The membranes from hydrophilic polymer (PVA) and in organic cross linker tetra ethyl orthosilicate (TEOS) called Silicon- PVA hybrid membrane were prepared and employed in the pervaporation removal of water from the azeotropic water/isopropyl alcohol/ECH feed mixtures. At the final state of epoxy resin production process, the ECH/IPA/water remains along with final product, and the recovery of the ECH/IPA from the ternary mixture by the vacuum distillation is a very complex and energy consuming process. Therefore the Si-PVA hybrid membrane was used to pervaporative dehydration of water/isopropyl alcohol/ECH mixtures. FTIR characterization was technique was used to confirm the PVA and TEOS crosslinking reaction. In the pervaporation output with increased of the TEOS content in the PVA-TEOS hybrid membrane, the permeation flux was decreased from the 0.14 kg/m2h to 0.05 kg/m2h and separation factor remarkably increased from 2099 to 13320 were observed.
