ALKYLIERUNG- UND ACYLIERUNGSREAKTIONEN |
摘要 |
<p>A process for the alkylation of aromatic substrates under supercritical or near-critical reaction conditions is described. In particular, a method for performing Friedel-Crafts alkylation reactions is disclosed under those conditions. Friedel-Crafts reactions may be effected using a heterogeneous catalyst in a continuous flow reactor containing a supercritical or near-critical reaction medium. Selectivity of product formation can be achieved by varying one or more of temperature, pressure, catalyst, flow rates and also by varying the ratios of aromatic substrate to alkylating agent.</p> |
