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. |
