Abstract:The 2-methylindole was synthesized by cyclization reaction from phenylhydrazine and acetone catalyzed by MCM-41 molecular sieves, which were supported ZnCl_(2) and other Lewis acids. Among AlCl_(3)/MCM-41, ZnCl_(2)/MCM-41 and FeCl_(3)/MCM-41 catalysts, ZnCl_(2)/MCM-41 which loading 4mmol/g show the best selectivity for the reaction, the yield of the product is 76.2%. |
Key words:molecular sieves; MCM-41; ZnCl_(2); AlCl_(3); 2-methylindole |
