Five　Bronsted　acidic　ionic　liquids　(ILs)　were　prepared　and　characterized　by　FT-IR,　H-1　NMR　and　(CNMR)-C-13.　Their　catalytic　activities　for　the　synthesis　of　2-propanol　(IPOH)　via　transesterification　of　isopropyl　acetate　(IPAc)　with　methanol　(MeOH)　were　investigated.　Among　all　the　tested　ILs,　[Ps-mim]HSO4　performed　best　and　was　used　as　catalyst　for　further　studies.　The　reaction　kinetics　were　carried　out　to　correlate　the　parameters　in　a　homogeneous　second　order　kinetic　model.　It　has　been　found　that　there　is　close　agreement　between　the　calculated　and　experimental　values.　The　high-pressure　batch　reactive　distillation　experimental　apparatus　was　set　up　in　order　to　enhance　the　conversion　of　IPAc.　A　high　conversion　of　IPAc　of　99.4%　was　obtained　under　the　optimal　reaction　conditions.　The　catalyst　[Ps-mim]HSO4　can　be　recycled　easily　by　a　rotary　evaporator　and　reusedwithout　any　further　treatment.　The　catalyst　had　been　repeatedly　used　for　four　times　and　no　obvious　changes　in　the　structure　of　catalyst　could　be　observed.　(C)　2016　The　Chemical　Industry　and　Engineering　Society　of　China,　and　Chemical　Industry　Press.　All　rights　reserved.
