Abstract：

Cation　exchange　resin　as　catalyst　for　the　preparation　of　isobornyl　acetate　by　the　esterification　of　camphene　is　widely　used　in　industry.　However　this　type　of　catalyst　is　easy　to　lose　its　activity　during　the　reaction.　In　this　paper,　the　deactivation　mechanism　and　regeneration　method　of　the　catalyst　(CT800)　were　investigated.　It　showed　that　the　deactivation　of　catalyst　was　mainly　caused　by　the　overlay　of　polymer　byproducts　on　the　resin　activity　centers.　The　deactivated　catalyst　can　be　regenerated　by　washing　with　ethanol.　The　activity　of　the　regenerated　catalyst　is　close　to　that　of　fresh　one.　This　proves　that　this　generation　method　is　effective.
