Abstract: The catalytic performance of acidic ionic liquids on the isobutane/butene alkylation was investigated. The acidic strength of ionic liquids has been improved by modified cation, anion and liquid acid. The amount of TMP in the [MBSIM]OTf alkylate can reach to 69.8%. The reaction system can be used 8 times and no significant decrease in catalytic performance.
Key words: alkylation; ionic liquid; isobutane; catalyst
