A　class　of　Bronsted-Lewis　acid　bifunctionalized　ionic　liquids　based　heteropolyacid　hybrid　(BLA-ILs-HPA)　solid　acids　were　developed　by　combining　the　double　sulfonic　groups　grafted,　ionic　liquids　based　heteropolyacid　hybrid　with　Lewis　acidic　centers　(M　=　Zn,　Co,　Fe,　Ni,　Cu).　The　prepared　BLA-ILs-HPA　show　both　Bronsted　and　Lewis　acidic　sites　with　extremely-high　acid　strength　and　enhanced　stabilities,　as　determined　by　FT-IR,　Py-IR,　TG,　XPS　and　P-31　solid　state　NMR　results.　BLA-ILs-HPA　were　successfully　applied　in　esterification　camphene　with　acetic　acid　to　produce　isobornyl　acetate,　and　dehydration　of　glucose　to　produce　5-hydrozymethylfural.　BLA-ILs-HPA　show　enhanced　catalytic　activities　in　comparison　with　various　acid　catalysts.　The　effects　of　reaction　temperatures,　initial　reactant　molar　ratio,　catalyst　dosage,　and　reaction　time　were　studied　in　detail.　The　optimal　reaction　conditions　were　obtained,　and　the　experimental　data　was　successfully　correlated　by　a　pseudohomogeneous　(PH)　reaction　kinetic　model　in　the　temperature　range　of　313.15-333.15　K.　The　calculated　values　obtained　by　the　reaction　kinetic　model　were　in　good　agreement　with　the　experimental　data.　Moreover,　as　a　heterogeneous　reaction　catalyst,　BLA-ILs-HPA　can　be　recovered　by　simple　treatment.　After　six　times　cycling,　the　decreasing　in　the　catalytic　activity　of　BLA-ILs-HPA　could　not　be　observed　significantly,　suggesting　their　good　reusability.　(C)　2020　The　Korean　Society　of　Industrial　and　Engineering　Chemistry.　Published　by　Elsevier　B.V.　All　rights　reserved.
