Acetic　acid　dehydration　is　significant　in　chemical　industry.　Pervaporation　has　attracted　increasing　attention　due　to　its　low　energy　consumption　and　environmentally　friendly　process.　However,　there　is　still　lack　of　efficient　membrane　materials　for　the　pervaporation　separation　of　acetic　acid/water　mixtures.　Therefore,　developing　new　material　to　prepare　pervaporation　membrane　is　currently　the　main　task.　In　this　study,　an　acid　stable　Zr-MOF　NH2-UiO-66　was　synthesized　and　incorporated　into　poly(ethyleneimine)　(PEI)　to　form　mixed　matrix　membranes　(MMMs)　for　separating　acetic　acid/water　mixtures.　The　NH2-UiO-66/PEI　MMMs　were　deposited　on　the　surface　of　NaA　zeolite　tubular　substrate　to　form　composite　membranes　using　dip-coating　method.　The　morphologies　and　structures　of　the　particles　and　composite　membranes　were　characterized　by　SEM,　EDX,　FTIR　and　contact　angle.　The　effects　of　membrane　preparation　conditions　on　the　separation　performance　were　investigated.　The　results　indicated　that　the　NH2-UiO-66/PEI　composite　membranes　showed　good　acetic　acid　dehydration　behavior,　because　of　the　high　porosity　and　hydrophilicity　of　the　particles.　Moreover,　the　particles　had　good　compatibility　with　polymer　and　strong　combination　with　substrate.　Therefore,　this　study　may　provide　a　new　material　and　facile　strategy　for　preparing　composite　membrane　in　the　separation　of　acetic　acid/water　mixtures.　(C)　2017　Elsevier　B.V.　All　rights　reserved.
