| Abstract: | Effects of reaction conditions, including WHSV, reaction temperature, N_2 content and time on stream, were studied on side chain alkylation of toluene with methanol over basic zeolite catalysts.Similar effects of reaction conditions on various zeolite catalysts were observed although the zeolites were different in properties.Based on the experimental results, a mechnism was proposed and discussed. |

| Keywords: | zeolite toluene methanol reaction condition side chain alkylation mechanism |
