Vapor Phase Synthesis of 3-Methylindole over a Ag/SiO2 Catalyst

Abstract

Abstract: Ag/SiO2 was used as an efficient catalyst for the vapor phase synthesis of 3- methylindole from aniline and 1,2-propanediol under atmospheric pressure. When Ag/SiO2 was calcined at 500 ℃ for 4 h and the molar ratio of H2O to H2 wa s 0.750 in the reaction, the yield of 3-methylindole was up to 35%. The Ag/SiO 2 catalyst with silver crystallites was active for the synthesis of 3-methyli dole.

Key words: silver, silica, supported catalyst, aniline, 1, 2-propanediol, 3-methylindole
