【Abstract】 The activity of the catalyst for methylation of cyclopentadiene was investigated. The results showed that the suitable reaction conditions are as follows: reaction temperature is 450 ℃, the ratio of cyclopentadiene(CPD) to methanol is 1∶2.5, the space velocity (ml·h \{-1\}/ml) is 1 200 h\+\{-1\}. Under the conditions the conversion for CPD is 60.6 %, the selectivity for methylcyclopentadiene (MCPD) 79.2 % and the yield of the MCPD 48.0 %.更多还原
