الملخص

Rice Husk (RH) are the natural sheathes that form on rice green during their growth and removed as waste during the processing of rice in the mill. The aim of this study is to investigate the benzylation of bromobenzene by benzyl chloride over a catalyst prepared from RH. In this study the catalyst rice husk ash-supported Fe +3 was prepared from rice husk ash (RHA) by dissolving it in NaOH and stirred for 24 h, then titrated against HNO3 contain Fe+3 ions until pH becomes 5 and aged for 24 h, filtered, washed and dried at 100 ˚C for 18 h. The prepared catalyst was used to investigate the benzylation of bromobenzene by benzyl chloride at different conditions. These conditions were temperatures (90, 80 or 70˚C), molar ratios (1:5, 1:15 or 1:25), and reaction times (0 hour, half hour, 1 hours, 2hours or 3hours). The reaction mixture were characterized by Gas Chromatography (GC) and compared with the result of benzylation of chlorobenzene at the same condition. The RHA-Fe showed no reactivity for the benzylation of bromobenzene at the studied reaction conditions. From this study it recommended to use another catalyst for this reaction instead of RHA-Fe.
