摘要：

Continuous Friedel-Crafts alkylation of mesitylene, C(6)H(3)Me(3), and anisole, C(6)H(5)OMe, with propene or propan-2-01 has been carried out in supercritical propene or CO(2) using a heterogeneous polysiloxane-supported solid acid Deloxan(R) catalyst in a small fixed bed reactor (10 ml volume); 100% selectivity for mono-alkylated products with 50% conversion could be obtained by adjusting the reaction parameters, e.g. temperature, pressure, flow rates, etc.
