Three　supported　ionic　liquids　(SILs)　were　synthesized　and　characterized.　And　the　catalytic　activity　for　the　preparation　of　ethylene　glycol　diacetate　(EGDA)　via　the　esterification　of　ethylene　glycol　(EG)　and　acetic　acid　were　studied.　Among　them,　[Silica-Ps-im]HSO4　performed　best　and　was　chosen　as　catalyst　for　further　study.　The　reaction　kinetics　experiments　were　carried　out　to　correlate　the　parameters　in　a　pseudo-homogeneous　second　order　kinetic　model.　It　has　been　found　that　there　is　good　agreement　between　the　calculated　values　and　experimental　data.　In　order　to　enhance　the　conversion　of　EG　and　yield　of　EGDA,　a　batch　reactive　distillation　experimental　apparatus　was　set　up.　A　high　conversion　of　EG　of　100%　and　yield　of　EGDA　of　99.14%　were　obtained　under　the　optimal　reaction　conditions.　The　reusability　test　shows　that　[Silica-Ps-im]HSO4　catalyst　has　excellent　utility　for　repeated　use,　the　ease　of　its　isolation　from　reaction　mixture　by　simple　filtration　is　beneficial　from　an　economical　point　of　view.　(C)　2015　Elsevier　B.V.　All　rights　reserved.
